Hisashi Ouchi, a Japanese nuclear technician, became known as the "Hiroshima of the Heisei era" after being involved in a criticality accident at a uranium reprocessing facility in 1999.

On September 30, 1999, Ouchi and two colleagues were involved in a criticality accident while processing uranium at a nuclear fuel processing facility in Tokaimura, Japan. The accident occurred when a solution containing uranium was accidentally mixed with a nitric acid solution, causing a chain reaction that released a large amount of radiation.

Ouchi received an extremely high dose of radiation, estimated to be between 17 and 20 sieverts (Sv). This radiation dose was so high that it caused extensive damage to his body, including his skin, muscles, and internal organs. Ouchi was rushed to the University of Tokyo Hospital, where he underwent extensive treatment in an attempt to save his life.

Despite the best efforts of the medical team, Ouchi's condition continued to deteriorate. He suffered from severe radiation burns, organ failure, and sepsis. On December 21, 1999, Ouchi died from multiple organ failure, becoming the first person in Japan to die from a nuclear accident.

Ouchi's death had a profound impact on Japan and the world. It led to a reassessment of safety procedures at nuclear facilities and a greater awareness of the dangers of radiation. Ouchi's story is a reminder of the importance of nuclear safety and the devastating consequences that can result from accidents involving radioactive materials.
