Suiin Emi (江見 水蔭, Emi Suiin, 17 September 1869 – 3 November 1934), born Tadanori Emi (江見 忠功, Emi Tadanori), was a Japanese novelist and journalist.

[citation needed] Born in Okayama into a shizoku (former samurai) family,[1] he travelled to Tokyo to join the army but instead joined the Kenyūsha literary society and quickly became celebrated during the Sino-Japanese War for his patriotic stories in the newspaper Chūō Shinbun.

[2] A pillar of the Meiji-era literary establishment, and the editor of Kobe Shinbun and Taiheiyo[3] as well as Senshibankō[4] and Kozakuraodoshi,[1] his writing is marred for modern readers by its imperialist outlook, one example being Osero, a new version of Othello commissioned for the Otojiro Kawakami troupe and set in the Taiwan of 1903, in which the Othello figure, the governor Lt. Gen. Muro Washirō, is a Japanese burakumin who has been sent to the island to suppress a rebellion.

[5] He was the first to refer to sumo as the national sport (kokugi), inspiring the name of the Ryōgoku Kokugikan stadium built in 1909.

[6] He died in Matsuyama.
