Born profoundly deaf in 1924, Seisaku Nakamura was intelligent but his deafness meant that he had difficult in communicating with people. His family were also shamed of him because of the disability.
Unable to talk to people, he buried himself in violent culture, spending much of his time watching films, especially enjoying those in which people died after being stabbed by Samurai swords
He began to fantasize about re-enacting the scenes he watched.
On August 22, 1938 when he was 14-years-old, he attempted to rape two women but they fought back so he murdered them. Three years later, on August 18, 1941 he committed his third murder and two days later he killed three more people.
On September 27, 1941 he murdered his brother, and severely injured his father, sister, sister-in-law, and nephew. He kept urges in check for a year but on August 30, 1942 he murdered a couple, their son and daughter and failed to rape a second daughter before fleeing the scene.
As with many other war-time criminals, the chaos caused by the conflict prevented the authorities from stopping Nakamura and the news blackout halted dissemination of information about his crimes.
The was finally arrested on October 12, 1942 and charged with nine murders, and confessed to two more. On November 11, 1942 his father, Fumisada Nakamura, took his own life in shame at what his son had done.
Despite a plea his his defence that he was insane, Nakamura was tried, found guilty and executed
