Kōtoku Shūsui

Kōtoku Denjirō (幸徳 傳次郎; November 5, 1871 – January 24, 1911), better known by the pen name Kōtoku Shūsui (Japanese: 幸徳 秋水; Japanese pronunciation: [koːtokɯ ɕɯːsɯi]), was a Japanese socialist and anarchist who played a leading role in introducing anarchism to Japan in the early 20th century. Historian John Crump described him as "the most famous socialist in Japan". He was a prominent figure in radical politics in Japan, opposing the Russo-Japanese War by founding the Heimin-sha group and its associated newspaper, Heimin Shinbun. Due to disregard for state press laws, the newspaper ceased publication in January 1905, and Kōtoku served five months in prison from February to July 1905.
