Biography of Mutsuo Toi

Early Life and Social Isolation

Mutsuo Toi was born on March 5, 1917, in the Okayama Prefecture, into a wealthy family. His parents died from tuberculosis when he was young, leaving him and his sister to be raised by their grandmother. Initially, Toi was a sociable young man, but at the age of 17, he became socially isolated after his sister got married in 1934. Essentially, he became one of the individuals belonging to the social group known as "hikikomori," who practice "acute social isolation" for various reasons.

Interest in Sada Abe and Writing

Toi became extremely interested in the story of a prostitute named Sada Abe, who strangled her lover and severed his penis in May 1936. This story served as the basis for the 1976 film "In the Realm of the Senses" (Ai no korîda). Following this unconventional story, Toi began working on his own novel titled "Yutokaiomaru." Like everyone else, he participated in a traditional rural event called "yobai," where he had to secretly crawl into a girl's room, specifically her bed, and with her consent, spend the night with her.

The Killing Spree

In his suicide note, Toi mentions that he was diagnosed with tuberculosis in May 1937 and also wrote about the rejection of his sexual advances by the girls in the village. Overall, his lengthy suicide note revealed how concerned Toi was about the social consequences of his tuberculosis, a disease that was incurable and fatal in the 1930s. He felt that the neighboring women became cold towards him as soon as they learned about his illness and despised him for his hypersexuality. Seeking revenge, Toi entered their homes and began killing them.

Final Words and Legacy

In his last message, Toi expressed regret that he was unable to kill certain individuals he wanted to, which led him to kill those he considered innocent. He also stated that he killed his grandmother because leaving her alive would have resulted in a shameful social label being placed upon her, branding her as the "grandmother of a murderer." Until Woo Bum-kon, a South Korean police officer, killed 57 people and injured 35 on April 27, 1982, Toi's incident was regarded as the most horrific case of a single perpetrator massacre in the world.
