Mutsuo Toi cut the electricity line to the village of Kamo on the evening of 20 May, which left the community in darkness. At around 1:30 a.m. on 21 May, he killed his 76-year-old grandmother by decapitating her with an axe in her sleep.[2] Armed with a modified shotgun, a katana, an axe, several daggers and 200 rounds of ammunition,[3] he strapped two flashlights to his head and prowled through the village like a youth engaged in "night-crawling" or "Yobai" (夜這い), entering the homes of his neighbors. He killed 29 neighbors (27 of whom died at the scene of the incident, while two others were fatally wounded, dying of their injuries later)[4] and seriously injured three others in about an hour and a half. This was almost half of the residents of the small community.[2] At dawn he committed suicide by shooting himself in the chest on a nearby mountain.[5][6]
Perpetrator
Mutsuo Toi, the 21-year-old responsible for the Tsuyama massacre, pictured before 1938
Mutsuo Toi (都井 睦雄, Toi Mutsuo, 5 March 1917 – 21 May 1938) was born in Okayama Prefecture to well-off parents. His parents died of tuberculosis when he was a baby, so he and his sister were brought up by their grandmother. He was originally outgoing, but at the age of 17 he became socially withdrawn after his sister married in 1934.
He was interested in the story of Sada Abe, the prostitute who, in May 1936, strangled her lover then severed his genitals. He had started writing a novel, Yūtokaiōmaru (雄図海王丸).[citation needed]
He took part in "Yobai" (夜這い) or "night-crawling", a rural custom which involved creeping into young women's bedrooms during the night to seek sexual intercourse.[4]
From his suicide notes it appears that after May 1937 when he was diagnosed as suffering from tuberculosis, the young women in the village rejected his sexual advances.
Location
The massacre was carried out in the small village of Kamocho Kurami, in the now city of Tsuyama. The village has since been merged with different towns and cities over the years due to depopulation. The village's population at the time of the massacre was 23 households and 111 people.[citation needed] After the massacre, some families moved away. Most of the residents in the village are now over 65 years old and have stated that no one has moved to Kurami since the massacre.
The house that Mutsuo Toi lived in was demolished in 2015, after sitting abandoned for years. The coordinates of this location are at the top of the page.
Suicide notes
Toi left several long notes which revealed that he was concerned about the social impact of his tuberculosis, which in the 1930s was an incurable fatal illness. He felt that his female neighbors became cold towards him once they knew of his illness, and that he was despised as hypersexual, and he also stated in the notes that neighbors insulted and treated him badly after he was found to have tuberculosis.
For revenge, he decided to enter their homes and kill them. He waited for the time when the women returned to their houses. The authorities were concerned, and his gun license was revoked. He however prepared swords and guns secretly.
He regretted that he would not be able to shoot some people he wanted to, as that would have involved killing people he regarded as innocent. He also wrote that he killed his grandmother because he could not bear leaving her alive to face the shame and social stigma that would be associated with being a "murderer's grandmother".
Films
The 1983 Japanese film, Ushimitsu no mura (Village of Doom), was based on the massacre. It stars Masato Furuoya as Tsugio Inumaru, an emotionally distraught young man who goes on a violent killing spree after his tuberculosis keeps him from serving in World War II. Furuoya committed suicide by hanging on 25 March 2003, twenty years after the film's release.[7]
^ ab"The List: The World's Worst Shooting Rampages". foreignpolicy.com. Archived from the original on 29 April 2007. Mutsuo Toi, a 21-year-old from a wealthy family, had been shunned by women and rejected from military service for having tuberculosis. Finally one night, he snapped. He cut the electricity to his village, bound two flashlights to his head, and shot or stabbed nearly half of the small community over the course of 90 minutes before then shooting himself at dawn. Before embarking on his rampage, he decapitated his grandmother with an ax. Aftermath: Toi left notes complaining of being ostracized for his disease. His bizarre attack has inspired at least four books, several films, and at least one play. Until 1982, his rampage was known as the world's worst massacre by a single individual.
