Kazutaka Komori

is a Japanese right-wing ultranationalist youth who attempted to assassinate Japanese journalist and magazine publisher Hōji Shimanaka in February 1961, in what became known as the Shimanaka incident. Komori sought retribution for a fictional story published in one of Shimanaka's magazines which featured a dream sequence in which the Emperor and Empress were beheaded by a guillotine. Shimanaka was away from home at the time of Komori's assault, and he ended up stabbing Shimanaka's wife and murdering his housemaid. Komori was 17 years old at the time of his attack. His mother, Tatsu, committed suicide when he was a young boy. Shimanaka was not at home but Komori murdered his 51-year-old maid and critically injured the publisher's wife. This murder and the assassination of Inejiro Asanuma by Otoya Yamaguchi led to the arrest of Bin Akao in 1961. Kenji Ino wrote in “Critique: Akao Bin: Rebel Radical Human”, page 133 (All Publishing, 1991):

Kazutaka Komori lost his mental balance while serving time in Chiba Prison. Whenever a meal was served, he repeatedly drowned his head in miso soup while shouting, “Long live the Emperor!" and repeatedly poured miso soup over his head. He is still in a hospital in Nagasaki Prefecture.
