Kiyohide Hayakawa was a senior member of Aum Shinrikyo who was found guilty of complicity in murder for killings carried out on the cult's behalf in 1989. The cases were the deaths of Tsutsumi Sakamoto and two others in Yokohama in November 1989, and of a young cult member in February of that year. The Tokyo District Court sentenced him to death on July 28, 2000. He was executed in Fukuoka on July 6, 2018, one of seven members of the cult executed that day.
Hayakawa joined Aum Shinrikyo in 1987 as one of its earliest members. He held a master's degree in city engineering and had worked for a major construction company before he joined. Inside the cult he held the title of construction minister and handled land acquisition and the expansion of its facilities. He was 51 at his sentencing in 2000 and 68 at his execution.
A young cult member died in February 1989. In November 1989 Tsutsumi Sakamoto and two others, one of them an infant, were killed in Yokohama. Hayakawa was found guilty of complicity in murder in both cases, with other charges in the Yokohama case.
On Friday, July 28, 2000, the Tokyo District Court sentenced Hayakawa to death.
On July 6, 2018, Japan executed seven members of the cult, including its founder, Chizuo Matsumoto, who was known as Shoko Asahara. The justice minister announced that the executions had been carried out earlier that morning. Hayakawa was executed in Fukuoka. The other six were executed at detention centers in Tokyo, Osaka and Hiroshima. He was the only one of the seven who had not been involved in the 1995 attack on the Tokyo subway. Six more members of the cult were executed on July 26, 2018.
Thirteen members of the cult were convicted and sentenced to death for their roles in a series of crimes, including the 1995 attack on the Tokyo subway. The July 2018 executions were the first of the thirteen to be carried out.
No killing beyond the two 1989 cases is attributed to him by a court. Accounts differ on whether he had any part in the 1995 attack on the Tokyo subway; he was not convicted over it.
