1944: Seisaku Nakamura, Hamamatsu Deaf Killer

(Thanks to Meaghan Good of the Charley Project for the guest post. -ed.)

On this date in 1944, nineteen-year-old serial killer Seisaku Nakamura was hanged for a series of horrific murders in wartime Japan. He killed at least nine people, perhaps as many as eleven, many of them while he was still a minor.

Nakamura, born deaf, was ostracized by both his family and society at large for his disability. Robert Keller, in his Asian Monsters: 28 Terrifying Serial Killers from Asia and the Far East,* notes:

It has been noted that many serial killers who suffer such ostracism retreat into a fantasy world, fueled most often by revenge fantasies. This was certainly the case with Seisaku Nakamura. He developed a near obsession with the Samurai culture and enjoyed watching movies where Samurai slaughtered their victims with lethal Katana swords.


The 47 Ronin (1941).

Yet on the surface all appeared normal. Seisaku was a bright boy who excelled at school. He was polite and deferential. He endured his condition without complaint. He’d grown, too, into a tall and strapping youth.

All was not normal, however.

According to Nakamura’s later confession, he committed his first two murders on August 22, 1938, when he was only fourteen. He tried to rape two women, he said, and murdered them after they resisted. This account has never been confirmed; perhaps he was boasting, or perhaps the murders did occur and the Japanese military government kept them out of the news.

Nearly three years passed before he committed another homicide: on August 18, 1941, Nakamura stabbed a woman to death and nearly killed another. Two days later, he stabbed and hacked another three victims to death. The police had a suspect description, but hushed up the information about the crimes for fear of causing a panic.

On September 27, Nakamura got into an argument with his brother at their parents’ home. The result was a bloodbath: he stabbed his brother in the chest, turned the knife on the rest of the family, stabbing and slashing his father, sister, niece and sister-in-law. Amazingly, only Nakamura’s brother died. Questioned by the police, the survivors refused to cooperate, saying they were afraid of retribution if they named their attacker.

Nearly a year passed with no bloodshed, but on August 30, 1942, Nakamura targeted another family. He saw a young woman on the street, followed her home, where her husband and three children were. Nakamura began his attack on the mother, and when her husband tried to defend her, he stabbed them both to death. He then slaughtered their two youngest children and turned his attention to the oldest, a girl. He started to rape her, then inexplicably broke off his assault and ran away, leaving her alive.

The survivor provided a good witness description to the police, who had their eye on Nakamura already; they had come to believe the reason his family wouldn’t say who attacked them the year before was because their attacker was one of their own.

The “Hamamatsu Deaf Killer” was arrested and quickly tried, found guilty, and sentenced to death in spite of his youth and the parade of witnesses ready to say he was insane.

Little is known about him and his crimes, as Japanese government suppressed most of the information.
