Fukushima and the Future: My Standpoint

— Posted inFukushima, Personal — 2 min read

My political and ideological position on Fukushima, nuclear power, and atomic energy.

I am neither fundamentally anti-nuclear nor an anti-government activist, nor do I seek to replace the ruling Liberal Democratic Party. At present, I hold no political stance advocating changes to Japan’s nuclear policy, for I lack the requisite knowledge to make informed assertions or take action on the matter.

Why did Japan become so deeply invested in nuclear energy?
Why have we continued to operate nuclear power plants without first establishing a final disposal site for nuclear waste?

These are questions that weigh on my mind, but I shall refrain from assigning blame here.

Regarding the meltdown following the Great East Japan Earthquake, I do not intend to condemn TEPCO, nor will I criticise the response of TEPCO and the government in the aftermath of the disaster. The reality is that Japan, complacent in its peace, had never faced an existential threat akin to an attack by Godzilla or an Angel. Until 3.11, our nation had neither the crisis response mechanisms nor the specialised organisations required to address such catastrophes at a governmental level. As a Japanese citizen, I find this regrettable—but it is a fact. Blame and recrimination will not propel us forward. We must tackle these challenges as one nation, united in purpose.

I was among those affected by 3.11, exposed to radiation in the immediate aftermath, and for the past fourteen years, I have continued to live in Fukushima, subjected to low-dose radiation exposure—a reality that will persist.

Is my declining health a consequence of this prolonged exposure?
Did my 81-year-old mother develop breast cancer four years ago due to radiation?

There is no scientific evidence to substantiate such claims, yet the thought lingers in my mind. As an ordinary citizen of Fukushima, I wish to share my thoughts, experiences, and doubts—engaging in discourse with the Fediverse. I want to hear your views.

My wish is singular:
That there shall never be another Fukushima.
That we shall leave no further burdens of this nature to future generations.

I ask you all—lend me your wisdom and strength.

“The Tale of Genji” and Me

— Posted inFamily, Literature, Personal, Philosophy — 8 min read

When I was young, my grandmother and father taught me a daily value:
“Do not behave in such a way that others would point at you behind your back.”
“Do not do anything that would become the subject of mockery.”
This teaching, passed down through generations, shaped the way I viewed my actions and their impact on others.

This mindset is reflected in The Tale of Genji, specifically in the Ninth Chapter, Aoi. The Emperor Kiritsubo, Genji’s father, rebukes his son for his reckless behaviour, warning him:

“Your lady was someone whom the late Crown Prince cherished dearly, but you are treating her as if she were an ordinary woman. This is truly regrettable. I consider those in the Saigū to be of the same importance as my own daughters, so you must not treat her with neglect, regardless of the circumstances. If you continue to behave whimsically and indulge in such infidelity, you will surely face harsh criticism from the public.”

This passage highlights the importance of maintaining one’s honour and awareness of how one’s actions are perceived. It aligns with the values instilled in me by my family: “cherishing one’s name”—to live with dignity and avoid shameful conduct.

As I grew up, I was continually reminded to act with consideration for how my behaviour reflected on both my family and myself. One of the lessons I took most to heart was to “live as a Samurai descendant, and behave as a Samurai.” The teachings of my father and grandmother instilled in me a sense of duty to preserve my family’s honour, both in personal conduct and in the broader societal context.

The Lineage and Culture of the Utsunomiya Family

The Utsunomiya family inherited prestigious bloodlines, including the Imperial family, the Fujiwara clan of the Five Regents, and the Uda Genji, and was deeply involved in the central power of the Kamakura Shogunate. Although not a direct descendant of Murasaki Shikibu, the family was able to align with the aristocratic values in The Tale of Genji, integrating them as part of their survival strategy. The value of “cherishing one’s name” became a guiding principle, which helped embed them within the broader Samurai society.

The Utsunomiya family strengthened its political position within the Shogunate through deep trust with the Genji, particularly Minamoto no Yoriyoshi, and through its connections with the Hojo and Hiki families. Their success was built on the ability to merge aristocratic traditions with warrior values, thus navigating the intense power struggles of the time and securing their influence.

1. The Aristocratic Lineage and Political Strategy Supporting Utsunomiya’s Prestige

Fujiwara no Kanetaka, the second son of the regent Fujiwara no Michikane, was a noble of the Fujiwara Five Regents. His primary wife was the daughter of the prestigious Uda Genji, Minamoto no Fuyoshi. Minamoto no Fuyoshi was the fourth son of the left minister Minamoto no Masanobu, whose lineage can be traced back to Emperor Uda. Masanobu’s daughter, Rinko, was the wife of Fujiwara no Michinaga and the mother of Empress Shoshi, consort of Emperor Ichijo. Thus, Kanetaka’s wife, a daughter of Minamoto no Fuyoshi, was a relative of Fujiwara no Michinaga and Rinko, making the Utsunomiya family heirs to the highest echelons of the imperial court, closely connected to the Fujiwara Five Regents, the Uda Genji, and the Ichijo Imperial family.

2. The Relationship between the Utsunomiya Family and “The Tale of Genji”

Fujiwara no Kenko (Daishōsanmi), the daughter of Murasaki Shikibu, served as a lady-in-waiting to Prince Atsuyasu, the fourth son of Emperor Ichijo. She is also remembered in works such as Teimon Chūnagon Monogatari, Go-Shūi Wakashū, and Hyakunin Isshu, fulfilling the role of a cultural heir to the courtly literary tradition. Considering the accounts in Eiga Monogatari, Fujiwara no Kenko married Fujiwara no Kanetaka and had a daughter, who later became the wife of Minamoto no Yoshimune. This connection between Fujiwara no Kenko and Kanetaka, although not a direct inheritance of Murasaki Shikibu’s bloodline, strongly influenced the Utsunomiya family, tying them to the literary and cultural values encapsulated in The Tale of Genji.

3. Utsunomiya Sōen and the Development of the Utsunomiya Family

Utsunomiya Sōen, the grandson of Fujiwara no Kanetaka, laid the foundation for the Utsunomiya family. His deepening trust with the Genji during the Heian period significantly influenced the rise of the Utsunomiya family’s power.

The Battle of the Tohoku (1051–1062), known as the Zenkunen War, was a pivotal conflict in the Mutsu Province (nowadays, Tohoku), where Minamoto no Yoriyoshi and his son Minamoto no Yoshiie led the Imperial forces against the Abe clan. This war was crucial for the Minamoto clan’s establishment as the leading warrior family, marking a turning point in their rise to prominence. The victory in the Battle of the Tohoku solidified the Minamoto clan’s position in the warrior society and laid the foundation for their future role in Japanese history, eventually leading to the establishment of the Kamakura Shogunate.

The Utsunomiya family’s connection to the Minamoto clan dates back to this war. Fujiwara no Sōen, the ancestor of the Utsunomiya family, played an important role in supporting Minamoto no Yoriyoshi and Yoshiie during the conflict. Sōen, a descendant of Fujiwara no Hidesato (Tawara Tōda), allied himself with the Minamoto forces, helping them secure their dominance in the region. This cooperation between the Utsunomiya family and the Minamoto was instrumental in the Utsunomiya family’s establishment as a prominent force in the Kanto region.

The impact of the Zenkunen War was not only limited to the Minamoto clan’s rise but also had a significant influence on the formation of the Utsunomiya family. The close relationship between the Utsunomiya family and the Minamoto continued to shape the family’s future, particularly during the Kamakura Shogunate, where the Utsunomiya family would play a vital role as loyal vassals.

4. Utsunomiya Yoritsuna and the Kamakura Shogunate

Utsunomiya Yoritsuna strengthened his influence within the Shogunate through his marriage to the half-sister of Hojo Masako, thus forging a closer connection with the Hojo family. Having been raised by the wet-nurse of Minamoto no Yoritomo, he also fostered strong relations with the Hiki family, consolidating his power within the Shogunate. Through these alliances, the Utsunomiya family grew from mere retainers to becoming one of the key figures in the Shogunate’s governance.

5. The Utsunomiya Family’s Political Influence within the Shogunate

The Utsunomiya family’s political standing was further solidified when they were granted the kanji “Yor” by Yoritomo, demonstrating the deep trust and bonds formed. Utsunomiya Yoritsuna was one of Yoritomo’s most trusted vassals, and through his connections with the Hojo family, he secured a prominent position as a relative of the Hojo clan’s ruling faction. The strengthened ties with the Hiki family played a significant role in expanding the Utsunomiya family’s influence within the Shogunate, consolidating their political power.

For Yoritomo, his brothers, including Minamoto no Yoshitsune, were rivals for the leadership of the Genji clan. However, through the presence of their wet-nurse, particularly Utsunomiya Yoritsuna, who was a trustworthy figure, he played an important role in strengthening Yoritomo’s position.

6. After the Fall

The Utsunomiya family fell into decline around 400 years ago and disappeared from the historical stage. However, the values from The Tale of Genji and the philosophy of “cherishing one’s name” still live on as a spiritual pillar for me and my family.

“The Zenkunen War” (The Battle of the Tohoku, 1051–1062)

The Zenkunen War (前九年の役, 1051–1062) was a critical conflict that occurred in the Mutsu Province (modern-day Tohoku). It was fought between the forces of the Minamoto clan, led by Minamoto no Yoriyoshi and his son Minamoto no Yoshiie, and the Abe clan, who held control over the region. The war was triggered by the unrest caused by the Abe clan’s refusal to submit to the Imperial Court’s authority.

Minamoto no Yoriyoshi was appointed by the court to quell the rebellion. His success in the campaign, particularly his decisive victory at the Battle of the Tohoku, solidified the Minamoto family’s status as the preeminent warrior family in Japan. The victory also marked the beginning of the Minamoto family’s rise to power, which would later play a crucial role in the establishment of the Kamakura Shogunate.

The war not only contributed to the consolidation of the Minamoto clan’s power but also had a lasting impact on the political landscape, shaping the future of the warrior class. The Utsunomiya family’s involvement in supporting the Minamoto during this time set the foundation for their rise to prominence in the Kanto region.

Rising Sea Levels and the Threat to Japan’s Nuclear Plants

The Risks: Rising Seas and Nuclear Infrastructure

There is an undeniable truth that many people are aware of but few dare to address: the threat that rising sea levels, driven by global warming, pose to Japan’s nuclear power plants. While the risks are evident to anyone who has paid attention to the mounting evidence of climate change, the conversation around it remains conspicuously absent. It is as though everyone knows the threat is real, but no one wants to say it aloud. This is not just a matter of scientific conjecture; it is a clear and present danger. The real question is why this topic is not being discussed more openly and why action seems to be delayed or avoided. Are we simply ignoring the problem, or are we afraid of the uncomfortable truths that might follow?

The majority of Japan’s nuclear facilities are situated between 5 and 15 metres above sea level. Historically, this may have been deemed acceptable, but with the rapid acceleration of climate change, such assumptions are no longer reliable. The Intergovernmental Panel on Climate Change (IPCC) forecasts that global sea levels will rise between 0.28 and 1.01 metres by the end of this century, with a potential rise of 2 to 3 metres over the coming millennia. Despite this, we continue to ignore the implications for nuclear power plants situated on low-lying coastal areas, in full knowledge of the looming threat. When the next great earthquake or super typhoon strikes, will we be caught unprepared? Why is this not at the forefront of our national conversation?

The evidence is there, but the question remains: why isn’t it being discussed? This is a scientific issue, but it is also a moral and political one. We must confront it openly. We can no longer pretend this problem does not exist simply because it is inconvenient or uncomfortable.

Lessons from History: The Heian Period and Rising Seas

History offers ample warnings regarding the dangers of underestimating nature’s immense power. During the Jomon Transgression, vast stretches of what are now the Osaka and Kanto plains were submerged. In the Heian period, what are today Japan’s economic and political epicentres—Tokyo, Yokohama, and Kawasaki—were little more than vulnerable coastal lowlands, frequently inundated. Ancient chronicles, such as the Wamyō Ruijushō and the Sarashina Nikki, attest to the profound shifts in Japan’s shoreline geography over the centuries. These are not abstract possibilities but rather concrete historical precedents. To disregard them is not only irresponsible; it is profoundly perilous.

The Imperative of Transparent Discourse

Having witnessed firsthand the devastation wrought by the Great East Japan Earthquake in Fukushima, my concern for nuclear safety—particularly with respect to the existential threat posed by rising sea levels as a consequence of global warming—transcends personal apprehension. This is a matter of profound significance, not only for those who have endured such calamities but for society at large. The central question is not merely whether rising seas will imperil nuclear power plants along Japan’s coastline, but whether we, as a society, possess the fortitude to confront this impending crisis with both scientific acuity and the democratic spirit that upholds free speech and reasoned dialogue.

In truth, it is entirely plausible that the relevant authorities are already taking effective measures, and as a private citizen, I may simply be unaware of these actions or lack the requisite knowledge to be fully informed. Nevertheless, the pressing challenge remains: we must engage in transparent discourse. We must scrutinise the evidence, weigh the risks, and ensure that all voices are heard so that informed, collective decisions may be reached. Our commitment must lie in a democratic process founded on intellectual honesty—where differences are resolved through dialogue rather than coercion—and in a continual effort to overcome prejudice and injustice. As we face these challenges, let us do so with courage and resolve, ensuring that we leave no negative legacy—be it in the long-term storage of nuclear waste or the perpetuation of societal injustices—and that we remain steadfast in building a better future for the generations to come.

Review | Lectin-Free Diet: Nov 2023 – Feb 2025

— Posted inHealth & Fitness — 5 min read

I am neither a doctor nor a researcher, and I lack expertise in medicine or healthcare. I am simply an ordinary citizen. My practice of the lectin-free diet is based on Dr. Steven R. Gundry’s books, “The Plant Paradox” and “Gut Check.” For a detailed understanding of the theory, I encourage you to refer to these books.

At present, I am following Phase 2. In line with the book’s recommendations, I am avoiding rushing into Phase 3. Until my symptoms—such as allergies, neuralgia, arthritis, and chronic sinusitis—improve further, I intend to adhere strictly to the Phase 2 dietary guidelines. For more details, I highly recommend reading the book.

Dietary Considerations:

Carbohydrate Restriction: To avoid blood sugar spikes, I am carefully limiting carbohydrate intake. For example, as of 10 February, I still have leftover New Year’s mochi. In previous years, I would consume an entire box within three days, but this year, I am restricting myself to two pieces per meal.

Consumption of High-Quality Fats: To promote fat metabolism, I am incorporating quality fats into my diet while ensuring I consume the necessary minerals to support mitochondrial function.

Fibre Intake: As a Japanese individual, I actively include seaweed in my diet.

Selection of Animal Protein: Following Dr. Gundry’s guidelines, I consume wild-caught fish, with occasional meat and eggs.

Dairy Products: I opt for goat’s cheese when available. Although expensive, it is a delicious choice.

Avoidance of Additives: To protect my kidneys, I minimise my intake of food additives.

Lectin-Free Practice: Avoiding lectins is a fundamental rule I strictly adhere to.

Fruit Restriction: Due to carbohydrate limitations, I consume fruit only a few times a month. While avocados are costly, I would like to include them in my salads.

Lifestyle Adjustments:

Beyond diet, I have realised the importance of getting more than eight hours of sleep, maintaining a regular routine, and engaging in moderate exercise. While challenging, I aim to incorporate these habits into my daily life.

Changes in Meal Patterns:

My mum, 81-year-old, who has schizophrenia, is responsible for meal preparation in our household. Due to her declining health, our meal frequency has reduced to two per day since last year. To compensate for the lost meal, I snack on nuts to supplement my intake of healthy fats. With the winter cold further affecting my mum’s health, preparing elaborate meals has become difficult. I hope to cook buri daikon and miso oden with her at least once this winter.

Achievements and Health Improvements:

Significant Reduction in Chronic Inflammation: Severe pain and inflammation have diminished, greatly improving my quality of life. My need for painkillers has completely disappeared, and joint pain has nearly resolved.

Improved Well-being: Brain fog has almost cleared, my skin has improved, and I no longer require sleeping aids. My weight has stabilised, and I am finding a better balance in my food intake before and after exercise. My gut condition has improved, evident in changes in my bowel movements, exactly as described in the book. The reduction of harmful gut bacteria and the increase in beneficial bacteria appear to be taking effect.

A Copernican Shift:

Surprisingly, I can live without rice without any issues. It makes me question the significance of Japan’s 2,000-year history of rice cultivation. My perspective has completely shifted.

Nutritional Realisation: Naturally, muscle and weight will not increase without strength training. However, through daily tracking of my weight and body fat, I have realised that the amount of protein required for muscle growth drastically decreases once gut health improves. My digestive absorption has enhanced. This aligns with what the book suggests. Looking back, my struggle to consume 100–140g of protein daily seems unnecessary. I spent so much on protein supplements, amino acids, milk, and yoghurt—only to discover that much less was required. This truly feels like a Copernican shift in my understanding of nutrition.

Dietary Challenges and Expenses:

Increased Food Costs: Eating healthily is expensive. Ironically, those looking to lose weight must spend more money to reduce fat. While I have cut down on expenses related to amino acids and protein supplements, my grocery bills remain high, and I feel the financial strain.

Guideline Adherence: I was unable to fully comply with recommendations regarding water, meat, and eggs. Dr. Gundry advises avoiding meat and eggs from grain-fed livestock, but in Japan, it is nearly impossible to find pork, beef, chicken, or eggs that do not come from grain-fed sources.

Water Issues: The guidelines recommend tap water, but the tap water in my old apartment is not drinkable. I purchase mineral water, selecting brands that resemble the water quality of my hometown, the Rokko Mountain range.

Conclusion:

The lectin-free diet has significantly improved my health, transforming my life by reducing pain and inflammation, improving sleep quality, and enhancing digestion. However, increased food costs remain a challenge, and I hope to expand my repertoire of meals. While it is difficult to adhere perfectly to the guidelines, I believe that true freedom lies within these constraints. To safeguard my health, I will continue this journey with enthusiasm. I hope everyone on the Fediverse will continue to watch over me with warmth and encouragement.

The Analects of Confucius

— Posted inLiterature, Personal, Philosophy — 2 min read

Though not a part of my family’s teachings, a passage from the Analects of Confucius has nevertheless shaped me profoundly.
Written in ancient Chinese over 2,000 years ago, the original text is complex, with interpretations varying across different editions. These differences are especially notable between the Japanese and English translations.
In my readings of the Analects, I have always focused on comparing several translations by different scholars, deepening my understanding with each version. However, I acknowledge that I am still far from fully grasping and embodying its teachings.
I intend to continue revisiting the text, hoping that its lessons will gradually become ingrained in me, like blood and flesh. It is a book I will learn from throughout my life.

Below is a passage that resonates with me deeply.

Book 1: Learning and Practising

1. The Master said, “Study, and at the proper time, revise—it is indeed a joy to the heart! With every revision, your understanding deepens, and you continue to improve.”

4. Zengzi said:
“I examine my conduct repeatedly each day:
When considering the needs of others, have I acted with a genuine heart?
In my associations with friends, have I been sincere?
And when sharing knowledge, have I truly understood it, or have I merely parroted it?”

Recipe for Sanbaizu

— Posted inFood, Health & Fitness — 4 min read

Sanbaizu is not only delicious, but also packed with health benefits that help maintain your well-being and energize you from the inside. It’s a condiment we incorporate into our daily meals for its positive effects, and it’s also a perfect choice for those avoiding lectins!

Ingredients:

  • Soy sauce (light soy sauce): 4 tablespoons
  • Mirin (hon-mirin): 4 tablespoons
  • Black vinegar (Gifu-produced black vinegar): 4 tablespoons

Instructions:

  1. In a bowl, combine 4 tablespoons of soy sauce, mirin, and black vinegar.
  2. Mix thoroughly, and it’s ready to serve!

Since this recipe doesn’t require heating, the flavors of the condiments remain intact. If you wish to remove the alcohol from the mirin, cover the bowl with plastic wrap and microwave it for 30 seconds to 1 minute at 500W. This will gently enhance the sweetness of the mirin.

Quality Condiments Are Key to Delicious Cooking Using only the highest quality soy sauce, mirin, and black vinegar is the secret to my cooking. When you choose the finest ingredients for your everyday condiments, the depth and umami of your dishes improve dramatically. Investing in quality condiments not only makes your meals tastier but also has a positive effect on your health.

Even if the ingredients cost more, I believe they are worth the investment. We save money in other areas of life but never skimp on the quality of our cooking. We prioritize investing in our meals, and that mindset is essential to our household. Spending on premium ingredients enriches our daily meals and nourishes our hearts.

Health Benefits of Sanbaizu Sanbaizu combines black vinegar, mirin, and soy sauce, each offering excellent nutritional value and health benefits.

  • Black vinegar is rich in amino acids, B vitamins, and citric acid. It helps with fatigue recovery, promotes metabolism, and improves blood circulation. It also works to balance the gut microbiota, aids digestion, and supports overall health. Additionally, black vinegar’s antioxidant properties boost immunity and help prevent aging.
  • Mirin adds natural sweetness without using sugar, thanks to the fermentation of rice and koji. It’s packed with umami, amino acids, and B vitamins, and helps with digestion. Even without heating, it gives a mellow sweetness, adding depth to your cooking.
  • Soy sauce (especially light soy sauce) is lower in salt, enhances the natural flavor of ingredients, and provides a refined umami. Tatsuno’s light soy sauce is low-sodium but still offers rich flavor, promoting a healthy diet.

Additional Health-Boosting Ingredients for Sanbaizu Adding these ingredients to Sanbaizu can amplify its health benefits:

  • Extra virgin olive oil (cold-pressed) is rich in polyphenols with strong antioxidant properties, supporting cardiovascular health. It improves blood flow and is effective in preventing arteriosclerosis. The oleic acid in olive oil helps lower bad cholesterol and maintain healthy cholesterol levels.
  • Black pepper promotes metabolism and aids fat burning, thanks to piperine. Combined with ground sesame seeds, which are high in antioxidant sesamin, this combination boosts digestion and immunity.
  • Ground sesame is rich in B vitamins and minerals, which assist energy production and contribute to the health of your skin and hair.

Our Heroes, Our Turn to Give Back

— Posted inFukushima, Personal, Uncategorized — 6 min read

Learning about the Operation Tomodachi lawsuit hit me hard. The very soldiers who came to our aid have suffered radiation exposure and now endure chronic health issues. I’m ashamed I didn’t know this sooner.

Back then, in the wake of the disaster, we lived in constant fear. Yet, their courage moved us beyond words. Eighty years ago, Japan and the US were locked in brutal battles across the Pacific. But we overcame that bloodshed and became friends—true friends. It felt like we had set an example for a world still trapped in cycles of war and hatred.

And now, those very soldiers are suffering. Knowing this, how can we stand by and do nothing? Fukushima cannot remain a perpetual victim, forever on the receiving end of aid. It’s my turn. This time, we give back.

The US lacks a universal healthcare system like Japan’s. Medical costs are crippling—are these soldiers getting the care they need? If radiation exposure forced them out of service, what became of their lives? Their families?

First, I need to gather information and assess what can be done. Perhaps a crowdfunding campaign, reaching out to those who were helped in 2011, channelling support through aid organisations to cover medical expenses and daily needs. There must be something we can do.

They stood by us when we needed them most. Now, it’s our turn to stand by them.
Another mission has found its way into my life.

Operation Tomodachi

Operation Tomodachi was a large-scale humanitarian aid and disaster relief operation conducted by the United States military in response to the Great East Japan Earthquake, which struck on March 11, 2011.

Overview of the Operation
Duration: March 12, 2011 – May 4, 2011
Participating Units:
U.S. Forces in Japan (U.S. Navy 7th Fleet, U.S. Air Force, U.S. Marine Corps, U.S. Army)
Fleet centred around the aircraft carrier USS Ronald Reagan
Approximately 24,000 U.S. military personnel
About 24 ships and 140 aircraft

Primary Activities:
Transportation of supplies (food, water, medical supplies, fuel, etc.) to the affected areas
Search and rescue operations for missing persons
Debris removal and recovery support
Monitoring and assisting with the Fukushima Daiichi Nuclear Power Plant crisis

Main Support Activities
1.Support from USS Ronald Reagan

Immediately following the earthquake, the 7th Fleet responded swiftly at the request of the Japanese government.
The USS Ronald Reagan deployed to the waters off the coast of Iwate and Miyagi Prefectures, where it conducted helicopter missions to transport relief supplies.
U.S. military aircraft carried out air bridges, delivering water, food, blankets, and fuel to the affected regions.


2.Marine Corps Landing and Support Operations

The U.S. Marine Corps (including the 3rd Marine Expeditionary Force based in Okinawa) landed on the coastlines of Miyagi and Iwate Prefectures to deliver supplies and engage in recovery work.


3.U.S. Air Force and Army Transport Operations

C-130 transport planes and helicopters were used to airlift supplies to isolated regions.
Army units provided infrastructure and road recovery support.

4.Support for the Fukushima Daiichi Nuclear Crisis

Unmanned aerial systems were employed to monitor radiation levels.
U.S. personnel assisted with the injection of cooling water.
Radiation data was collected in the vicinity of Fukushima.


Challenges and Issues
Exposure of U.S. Military Personnel
Some members of the crew aboard USS Ronald Reagan, who operated off the coast of Fukushima, were exposed to radiation.
Subsequently, several of these personnel filed lawsuits seeking compensation from Tokyo Electric Power Company, claiming health issues related to the exposure (the “Tomodachi Operation lawsuit”).

The Tomodachi Operation Lawsuit

The “Tomodachi Operation Lawsuit” concerns the legal action taken by U.S. military personnel, who, after the Great East Japan Earthquake in 2011, were exposed to radiation while assisting with the Fukushima Daiichi nuclear disaster. These servicemen filed a lawsuit against Tokyo Electric Power Company (TEPCO), seeking compensation for health damage.

Background
In the aftermath of the disaster, the United States military swiftly initiated “Operation Tomodachi”, which included the nuclear-powered aircraft carrier “USS Ronald Reagan” operating off the coast of Fukushima. However, complications arose when the ship took in contaminated water, which was processed by its water filtration systems, resulting in radiation exposure to some of the crew.

The Lawsuit’s Progression
In December 2012, eight servicemen filed a lawsuit in a federal court in California. The number of plaintiffs subsequently grew to around 400 by 2020.
Their claim was straightforward: TEPCO underestimated the effects of the radiation, failing to provide adequate information. They further argued that exposure to the radiation had caused severe health issues, including cancer, thyroid disorders, and infertility, and sought compensation exceeding $1 billion (approximately 150 billion yen).

Legal Developments
TEPCO has denied the existence of a causal link between the radiation exposure and the health damage, asserting that no such direct connection has been proven. The Japanese government has also maintained that the radiation levels were not harmful.
In 2020, the California court decided to continue the trial, though no final verdict has yet been reached.

Impacts and Debate
Relations between the U.S. Military and the Japanese Government
Initially, both the Japanese government and the U.S. military downplayed the risks of radiation exposure. However, this lawsuit has brought the health risks into sharper focus.

Health Damages to U.S. Military Personnel
Many of the servicemen involved in the lawsuit suffer from severe health conditions, with support organisations actively campaigning for compensation.

Responsibility of Tokyo Electric Power Company
The Fukushima Daiichi disaster remains the subject of numerous lawsuits both domestically and internationally, with this case becoming a key point of scrutiny in determining the responsibility of TEPCO.

The Roots of Suffering: Ignorance, Delusion, and Wrong View in Buddhist Philosophy

— Posted inLiterature, Personal, Philosophy — 2 min read

This is my personal admonition:Ignorance (avidya) and delusion (mūnyō) manifest as the veils that obscure our perception of truth, steering us toward suffering. The concept of “wrong view” (jaken) refers to perceiving the world in a misguided way, often at odds with reality. These erroneous views spring from ignorance or delusion, leading to misapprehensions about causality, the nature of phenomena, and the adoption of false beliefs.

Ignorance is the absence of knowledge, while delusion represents the failure to grasp the truth. Conversely, wrong view signifies the state of holding misguided beliefs, whether intentionally or unknowingly. An example of this is the false belief that “happiness can be attained through wealth.” Such views only serve to reinforce actions and judgments rooted in illusion and misunderstanding.

In essence: ignorance is “not knowing,” delusion is “losing sight of the truth,” and wrong view is “holding distorted perceptions.”

These teachings are grounded in several Buddhist scriptures, each offering insights into the interconnected nature of these concepts:

The Lotus Sutra
This scripture expounds on how wrong views, delusion, and ignorance serve as the root causes of suffering. It specifically addresses the “Four Wrong Views” (shijaken), providing a clear understanding of how these erroneous perspectives shape our experience.

The Pure Land Sutra
Here, the emphasis is placed on ignorance and delusion as the primary sources of suffering. The path to liberation is offered through the rebirth in the Pure Land, where one can overcome these afflictions and attain enlightenment.

The Alaya-Vijnana Sutra
Through the concept of Alaya-Vijnana (the “storehouse consciousness”), this sutra illuminates how ignorance and delusion infiltrate the mind, fostering wrong views and misleading perceptions.

The Madhyamaka Karika (Nāgārjuna’s Middle Way)
In this profound text, Nāgārjuna offers a theoretical analysis of how delusion, wrong views, and defilements lead beings astray, reinforcing their suffering. It further highlights how ignorance obstructs the path to liberation, particularly through the doctrine of emptiness (śūnyatā).

These scriptures intimately weave together the concepts of delusion, ignorance, and wrong view, positioning them as fundamental sources of suffering within Buddhist philosophy.

The Gray Rhino Strikes:Our Millennia-Long Responsibility

— Posted inFukushima, Science, Technology — 5 min read

If a caldera eruption were to occur in proximity to the Fukushima Daiichi Nuclear Power Plant, the consequences would be nothing short of catastrophic. The volcanic ash would not merely fall upon the surrounding regions of Fukushima, obstructing the cooling mechanisms of the nuclear reactors, but the fusion of radioactive materials with the ash would exacerbate the risk of widespread dispersion. In such a scenario, it is highly probable that nations across the Northern Hemisphere would face direct repercussions, rendering them far from unaffected.

Dispersal of Radioactive Materials
Should a nuclear accident transpire, radioactive substances such as iodine, caesium, and strontium would be released into the atmosphere, and owing to prevailing wind patterns and atmospheric conditions, these materials would disperse over vast expanses. With strong winds or atmospheric disturbances in play, radioactive substances could travel hundreds of kilometres. In the most extreme of circumstances, the effects could reach across the entire Northern Hemisphere, with regions experiencing high concentrations of radiation potentially being impacted even thousands of kilometres from the source. The IAEA’s reports have outlined the trajectory of radioactive materials and the influence of meteorological conditions on such dispersion (source: IAEA, Preparedness and Response for a Nuclear or Radiological Emergency, 2011).

The Scope of Impact
In the aftermath of the Chernobyl disaster in 1986, radioactive materials were carried throughout Europe and North America due to prevailing winds. Within mere days of the incident, radiation spread to regions thousands of kilometres away, with particularly severe effects in Russia, Ukraine, Belarus, and parts of Western Europe. Thus, in the worst-case scenario, radioactive materials could be dispersed across the entire Northern Hemisphere, leading to widespread contamination and severe radiation exposure.

Risk of Acute Radiation Exposure
As radioactive materials spread over such vast distances, the risk of acute radiation exposure becomes alarmingly significant, particularly for neighbouring countries or even distant continents. If radiation were to descend in concentrated doses, regions exposed to over several hundred millisieverts could witness residents suffering from acute radiation sickness, manifesting as nausea, vomiting, diarrhoea, and immune system deficiencies. According to IAEA guidelines, health effects become apparent with exposure to more than 100 millisieverts of radiation (source: IAEA, Safety of Nuclear Reactors, 2018), and in the direst of circumstances, these effects could manifest over vast swathes of the globe, leading to extensive health consequences across the Northern Hemisphere.

The Risk of Caldera Eruptions in Japan
Japan, an archipelago blessed with many active volcanoes, faces an especially dire risk from caldera volcanoes, capable of causing catastrophic damage. Historical records reveal frequent caldera eruptions, particularly in the Kyushu region, where the Aso and Kikai calderas pose significant risks of re-eruption. Furthermore, caldera volcanoes are also found in the Tohoku and Hokkaido regions, where large eruptions have occurred in the past.

Indeed, the caldera risk in the vicinity of the Fukushima Daiichi Nuclear Power Plant epitomises the “gray rhino” phenomenon.
The “gray rhino” metaphor, coined in the work The Gray Rhino: How to Recognize and Act on the Obvious Dangers We Ignore (2016) by economist Michele Wucker, explores the theme of how societies tend to overlook imminent and conspicuous risks—represented by the “gray rhino”—until they become insurmountable crises. She underscores the challenge of recognising and responding to unavoidable dangers that we too often ignore (source: Michele Wucker, The Gray Rhino: How to Recognize and Act on the Obvious Dangers We Ignore, 2016).

According to research conducted by Professor Yoshiyuki Tatsumi and Associate Professor Keiko Suzuki at the Graduate School of Science, Kobe University, the likelihood of a caldera eruption of significant magnitude within the Japanese archipelago in the next century is approximately 1% (source: Kobe University, KOBE-U.AC.JP).
This study was published in the Proceedings of Japan Academy, Series B, Physical and Biological Sciences on November 11, 2014 (source: Kobe University, KOBE-U.AC.JP).

Long-Term Management of Radioactive Waste
Amid the ongoing decommissioning of the Fukushima Daiichi Nuclear Power Plant, the management of radioactive materials with exceptionally long half-lives, such as Plutonium-239 (Pu-239), over an astonishing period of approximately 24,000 years, presents an unfathomable challenge. Within this vast timespan, humanity will inevitably face numerous natural disasters and unforeseen risks. The caldera eruption risk surrounding Fukushima Daiichi stands as the quintessential embodiment of the “gray rhino.”

Should such a massive caldera eruption transpire, the resultant volcanic ash and radioactive materials would merge, dispersing contamination over vast territories. Were this risk to materialise, the management of the radioactive waste at Fukushima Daiichi would become all the more challenging, triggering further health risks and environmental repercussions. This scenario would only serve to underscore the complexity and difficulty of managing safety over the long term, placing a profound and enduring responsibility on future generations across millennia.

Thus, risk management surrounding Fukushima Daiichi is not merely a contemporary issue but a monumental responsibility extending far into the future, encompassing multiple generations and demanding our collective foresight and action.

Neglecting this issue is not an option.

The Reality of Fukushima Daiichi Decommissioning – Is This Merely Japan’s Concern?
The decommissioning of the Fukushima Daiichi Nuclear Power Plant is projected to take 30 to 40 years. This process entails the removal of spent nuclear fuel, the dismantling of structures, and the reduction of radiation levels—an undertaking of immense complexity and duration. However, throughout this period, the risk of a catastrophic accident remains ever-present.

How many people truly acknowledge this reality?

The extraction of spent nuclear fuel from storage pools and the dismantling of damaged infrastructure are particularly hazardous operations, conducted under extreme radiation exposure and harsh conditions. Furthermore, the risks involved today may well exceed those of the previous disaster.

Within the ruined reactor cores, vast quantities of highly radioactive molten fuel debris (corium) remain inaccessible. These materials emit radiation so intense that mere exposure could prove fatal. The very act of attempting to remove them introduces a precarious scenario:

What if complications arise during fuel retrieval?
What if an unforeseen earthquake or tsunami strikes once again?
The 2011 disaster resulted in the widespread dissemination of radioactive contaminants through the atmosphere and the ocean, impacting nations far beyond Japan’s borders. To this day, treated but still radioactive water continues to be released into the Pacific.

Is this truly a distant issue of no concern to the rest of the world?

Despite advancements in risk management, absolute safety remains unattainable. Should global attention wane, the next accident could surpass the scale of Fukushima.

This is not merely Japan’s predicament.
This is a matter that concerns the future of us all.

Long-Term Management of Nuclear Waste and Plutonium-239 (Pu-239)

Latest Update: 24 February 2025

1. 240,000 Years—A Legacy We Cannot Ignore

Plutonium-239 (Pu-239) is an exceptionally dangerous radioactive substance produced during nuclear fission reactions. Its half-life is approximately 24,000 years, meaning that it will take at least 240,000 years—ten times its half-life—for its radioactivity to diminish to 1/1000 of its original level and become effectively harmless to the human body. This immense timescale underscores the fact that the management of Pu-239 is a challenge far beyond any single generation.

The number 240,000 years is also the origin of this blog’s title. It serves as a stark reminder that this issue transcends human time perception, extending far beyond the scope of recorded history and human civilisation as we know it. The decisions made today will not only impact the present generation but will leave consequences that stretch across an almost inconceivable span of time.

2. The Necessity of Long-Term Management

To safely manage the radioactivity of Pu-239, long-term monitoring and containment are absolutely essential. Geological disposal is considered the most promising method, which involves burying radioactive waste deep within stable geological layers to prevent radiation from reaching the surface. Given that Pu-239 will continue to emit radiation over millennia, it is imperative to isolate it in a secure underground repository to mitigate its impact on human health.

3. The Cost of Long-Term Management

The construction and maintenance of geological disposal facilities incur enormous costs. For example, Finland’s Onkalo facility has a construction cost estimated at around 1 trillion yen (8 billion euros). This figure not only covers the building of the facility but also its long-term maintenance, which will require monitoring and upkeep over hundreds, even thousands of years. The annual costs for surveillance and maintenance could reach several hundred billion yen.

In Japan, the management of radioactive waste, including Pu-239 from the Fukushima Daiichi Nuclear Disaster, is expected to require a similar level of investment. Although specific construction and operational costs remain undetermined, long-term management is anticipated to cost trillions of yen.

4. Responsibility to Future Generations

The disposal of radioactive materials presents challenges that cannot be fully resolved with current technology. Nevertheless, it is our responsibility to ensure that the burden is not placed on future generations. It is imperative to develop long-term management plans and implement measures that minimize the risks. What we do now will have a lasting impact on future generations.

The choices we make today will determine the risks borne by those yet to be born. It is our duty to prevent passing this burden onto the next generation without ensuring a proper solution. Our current decisions will shape the future.

Everyone, I ask you all—lend me your wisdom and strength.

Further Considerations

The radioactive decay of Pu-239 follows a predictable pattern. With a half-life of 24,000 years, its radioactivity will decrease by half over that period, then continue halving to 1/4, 1/8, and so on. To reach 1/1000 of its original level, it will require approximately ten times its half-life. This underscores the immense timescale required before Pu-239 can be deemed safe.

Minority Report

“Akko-chan,” my mum, aged 81, schizophrenia, is gradually growing weaker. It may not be today or tomorrow, and probably not even a year from now, but the day of saying “goodbye” is certainly drawing near. The time I can spend with Akko-chan is limited. Since there is so little time left, I want to do whatever I can to show my gratitude and respect. I want her to live out her remaining years peacefully, and I will do whatever it takes to make that happen. I will give it my all.

My mum’s vitality comes from the time she spends with her granddaughters. So, I want to increase that time as much as possible. Perhaps because I don’t have a wife or children, these two nieces are especially dear to me. It’s been 14 years since they evacuated and left Fukushima after the 3.11 disaster. The time my Mum spent with them has been limited. The four years during the pandemic, when they couldn’t meet, was a big blow. Now is the time to recover what was lost during that period.

I’ve decided to think carefully about what I can do for my Mum and nieces and take action. “If I change, the world changes.” I believe in ‘yuishiki.’ Small actions can bring big changes. Time is limited. I will face it with all my effort, doing what I can now, and doing what should be done now. That is the filial piety I can offer and a step forward toward the future.
