In 2003, Justice Ministry formed a special team to investigate 1,566 prisoner deaths from 1993 to 2002. A preliminary report suggested that nearly one third of the cases involved suspicious circumstances. However, in June, the Ministry announced that there was evidence of abuse only in the two Nagoya fatalities. Regarding the other suspicious deaths, the Ministry said that approximately 10 deaths could be attributed to poor medical care. The authorities reported they had lost the documentation on nine deaths in Tokyo's Fuchū Prison. The remaining deaths were determined to be "not suspicious".
