Hiroko Nagata - Criminal Trial, Sentence, Illness, and Death

Criminal Trial, Sentence, Illness, and Death

Hiroko Nagata was sentenced to death in the Tokyo District Court on June 18, 1982. On September 26, 1986, the Tokyo High Court upheld her death sentence. On February 19, 1993, the Supreme Court of Japan upheld her death sentence. Nagata submitted a plea for a retrial, which was declined by the courts on November 28, 2006.

Nagata wrote several books during her time in prison and attracted the attention of a support group. Nagata's supporters reported that she had suffered from declining health, including a brain tumor, for several years which had gone untreated. She underwent surgery for a brain tumor in 1984. Nagata collapsed from brain atrophy in 2006 and was transferred to a medical prison in Hachioji. She returned to the Tokyo Detention House in 2007, but was bedridden.

On October 11, 2008, it was revealed that Nagata had fallen into a critical condition due to the tumor, so her family was called for visitation to the Tokyo Detention Center. Nagata died on 5 February 2011.
