Hisashi Ouchi’s Background

Hisashi Ouchi, a 35-year-old lab specialist, found himself working at the Tokaimura thermal energy facility in Japan. Born in 1965, he grew up in a country that had turned to nuclear power due to its limited natural resources and dependence on imported energy. His job was critical in a region rapidly becoming known for its nuclear industry.

The Tokaimura Nuclear Accident

The fateful day was September 30, 1999. Hisashi Ouchi, along with two colleagues, Masato Shinohara and Yutaka Yokokawa, was given a task that would change their lives forever. They were asked to mix enriched uranium with nitric acid, a process that should have been done with automated pumps but was instead done by hand.

The consequences of their inexperience and haste were disastrous. They poured an excessive amount of uranium into the wrong container, triggering a nuclear chain reaction. A blinding blue flash confirmed the release of deadly radiation.

Hisashi Ouchi’s Unprecedented Radiation Exposure

Ouchi’s exposure to radiation was beyond comprehension. He received a staggering 17 sieverts, an amount that had never been recorded in human history. Upon arriving at the hospital, he was in immediate pain, vomiting violently, and had lost consciousness.

The Fight for His Life

Doctors were shocked by the condition in which Hisashi Ouchi arrived at the University of Tokyo Hospital. He had virtually no white blood cells, leaving him with no immune system. This made him vulnerable to infections, so he was placed in a special ward to minimize the risk.

His first week in the hospital was a whirlwind of skin grafts and blood transfusions. A revolutionary approach was suggested: stem cell transplants. This procedure had never been tried on radiation victims before. Ouchi’s sister donated her stem cells, and for a brief moment, it seemed like it might work. But the radiation had destroyed his DNA, and the new cells couldn’t survive.

Despite the excruciating pain and suffering, Ouchi’s family insisted on continuing experimental treatments. His skin began to melt from his body, but the doctors revived him after multiple heart attacks. However, his fate was sealed. On December 21, 1999, after 83 agonizing days in the hospital, Hisashi Ouchi succumbed to multi-organ failure, finally finding relief from his torment.

The Aftermath of the Tokaimura Disaster

The immediate aftermath of the Tokaimura nuclear accident was chaotic. Villagers within six miles of the facility were ordered to stay indoors for 24 hours. Over the next 10 days, 10,000 people were checked for radiation, with more than 600 people suffering from low-level exposure.

Masato Shinohara, one of Ouchi’s colleagues, fought for his life for seven months but ultimately succumbed to lung and liver failure in April 2000.

Yutaka Yokokawa, the supervisor, was released after three months of treatment for minor radiation sickness. However, he faced criminal charges of negligence in October 2000. The company responsible for the accident, JCO, paid $121 million in compensation to affected locals.

The Tokai power plant continued to operate under different management until the 2011 Tōhoku earthquake and tsunami, which led to its automatic shutdown. Since then, it has remained inactive.


  • Is Hisashi Ouchi the most radioactive man in history? Yes, Hisashi Ouchi’s exposure to 17 sieverts of radiation is unparalleled in human history.
  • What happened in the Tokaimura nuclear accident? The accident occurred when three workers, including Hisashi Ouchi, mixed enriched uranium with nitric acid by hand, resulting in a nuclear chain reaction.
  • Did anyone else survive the accident? Hisashi Ouchi’s colleague, Yutaka Yokokawa, survived with minor radiation sickness, while another colleague, Masato Shinohara, fought for his life but ultimately passed away.


The story of Hisashi Ouchi is a tragic reminder of the catastrophic consequences that can result from nuclear accidents. His unparalleled radiation exposure and the heroic efforts of medical professionals to save his life serve as a testament to the resilience of the human spirit in the face of unimaginable suffering. The Tokaimura nuclear accident is a somber chapter in the history of nuclear power, underscoring the need for rigorous safety measures and the devastating toll of human error.

Why was Hisashi Ouchi kept alive?

Hisashi Ouchi was kept alive in an attempt to save his life and study the effects of extremely high radiation exposure. Despite his critical condition, medical professionals and his family made efforts to find treatments that might mitigate the damage caused by radiation.

What exactly happened to Hisashi Ouchi?

Hisashi Ouchi was exposed to an unprecedented level of radiation, approximately 17 sieverts, in a nuclear accident at the Tokaimura power plant in Japan. This exposure led to severe radiation burns, internal organ damage, and a compromised immune system, ultimately resulting in his tragic death.

What is the longest-living radiation survivor?

The title of the longest-living radiation survivor may vary, but individuals who have survived high levels of radiation exposure often face significant health challenges and shortened lifespans. Hisashi Ouchi, who survived for 83 days, is one notable example.

Who was the worst radiation victim?

Hisashi Ouchi is often regarded as one of the worst radiation victims in history due to the incredibly high level of radiation he was exposed to. His condition and suffering became emblematic of the devastating effects of radiation exposure.

What is the walking ghost phase?

The “walking ghost phase” is a term used to describe the period shortly after a severe radiation exposure when a person may appear relatively stable but is actually experiencing the onset of fatal radiation damage. It is a critical phase when irreversible harm is occurring within the body.

Has anyone survived radiation?

Yes, some individuals have survived radiation exposure, but the extent of survival and long-term health varies depending on the level of exposure. High levels of radiation, like in Hisashi Ouchi’s case, often lead to severe health complications and shortened lifespans.

Can Hisashi Ouchi talk?

During his 83 days of hospitalization, Hisashi Ouchi’s ability to communicate would have been severely compromised due to the extensive damage to his body. However, it’s essential to note that he likely would have been in significant pain and discomfort throughout his ordeal.

How much radiation can a human take?

The amount of radiation a human can tolerate depends on various factors, including the type of radiation, the duration of exposure, and individual susceptibility. Generally, exposure to more than a few sieverts of ionizing radiation is considered fatal without prompt medical intervention.

How much radiation did Hisashi get?

Hisashi Ouchi received an astonishing 17 sieverts of radiation exposure, an unprecedented and lethal dose that caused severe radiation burns, internal organ damage, and ultimately led to his death.
