Hiroaki Hidaka (日高 広明 Hidaka Hiroaki, April 1962 - December 25, 2006) was a Japanese serial killer.


Hidaka was originally a top student but failed to enter the University of Tsukuba, his target college. He entered the Fukuoka University instead, but eventually dropped out. He often borrowed money, drank and went to prostitutes. In April 1989, he moved to Hiroshima and began to work as a taxi driver.

He married in 1991, and had a daughter in 1993, but his wife entered a mental hospital. He killed four prostitutes between April and September 1996. One of his victims was a 16-year-old girl who engaged in Enjo kōsai. He was arrested on September 21, 1996. He robbed them of 240,000 yen, but he paid 120,000 yen to have sex with them, so he actually robbed them of 120,000 yen.

The district court in Hiroshima sentenced Hidaka to death on February 9, 2000, and then he didn't appeal. He was executed by hanging on December 25, 2006.
