Hirofumi Daimatsu (大松 博文, Daimatsu Hirofumi, 12 February 1921 – 24 November 1978) was a Japanese volleyball coach and a Japanese politician. He led Oriental Witches, nickname of "Nichibo Kaizuka", a factory volleyball team of Dai Nippon Spinning Co., Ltd. (later, Nichibo, thereafter, Unitika) in Kaizuka, Osaka given by the reports of European media when they achieved 24 consecutive victories against other national teams on the expedition to Europe,[1] to world champion.
Three months later, he was called up for military service and thrown into operation of Imphal named "Bleached bones road" after moving around China.[2] Second lieutenant Daimatsu's unit of 40 men was routed and had to cross mountains, having fevers of 40 because of malaria and/or amebic dysentery without food.[2]
After World War II, in 1953 he became the coach for the factory women's volleyball team of Nichibo Kaizuka, namely Oriental Witches which started from a factory volleyball team located in Kaizuka City and evolved into the Japanese National Team.[3] Oriental Witches achieved 175 consecutive wins by Daimatsu's severe training, so he was called "Demon Daimatsu".[1] As the coach of Japanese National Team, he led the Japanese Women's Team to a silver medal in the World Championship in 1960, a gold medal in the World Championship again in 1962 and a gold medal in Tokyo Olympics in 1964.[1][3]
