Akiyoshi Umekawa

Akiyoshi Umekawa (梅川 昭美, Umekawa Akiyoshi, March 1, 1948 – January 28, 1979) was a Japanese mass murderer who killed a woman on December 16, 1963, and shot dead four people on January 26, 1979. Mass media also used a number of different possible readings of his given name, including Teruyoshi, Terumi, Akimi and Akemi. He was one of the rare criminals who was shot dead by Japanese police.

Umekawa was born in Otake, Hiroshima Prefecture.He was a great reader and loved hardboiled fiction. On December 16, 1963, while he was 15 and still a minor, he killed a woman. Although he was a murderer, he was still allowed to have guns because Japanese juvenile law protected his criminal history. He also saw the film Salò, or the 120 Days of Sodom. He wanted to make a big incident 15 years after he committed the first murder.

Umekawa shot dead two employees and two policemen on January 26, 1979, in a Mitsubishi Bank in Sumiyoshi-ku, Osaka. He took 40 hostages at the bank. He asked them, "Do you know Sodom no Ichi (Japanese alternative title of Salò, or the 120 Days of Sodom)?" He stripped women of their clothes.

Rokuro Yoshida, who joined criminal investigations of Kiyoshi Ōkubo and United Red Army, was appointed as the incident commander. "Zero" Company of the 2nd Riot Police Unit of the Osaka Prefectural Police Headquarters (one of the predecessors of the Special Assault Teams) were called, which was the first case in the history of Japanese Police Tactical Units. They fatally shot Umekawa on January 28, 1979. Yoshida stated there was no alternative to deadly force.

His crime affected Japanese youths. Oikawa Neko [ja], a lyricist, said that he was the main reason why she did not have leftist views. The story of the film Tattoo Ari was inspired by him, but an alternative name was used for him in the film.
