Inejiro Asanuma (?? ???, Asanuma Inejiro, December 27, 1898 – October 12, 1960) was a Japanese politician and leader of the Japan Socialist Party.
Originally a right-winger in the 1930s, Asanuma was unusual in post-war Japan for his forceful advocacy of socialism, his support of the Chinese Communist Party, and his criticism of U.S–Japanese relations, which was particularly controversial.
Asanuma was assassinated with a yoroi-doshi, a traditional sword, by ultranationalist Otoya Yamaguchi while speaking in a televised political debate in Tokyo.
His violent death was seen in graphic detail on national television, causing widespread public shock and outrage.
