Kangan Giin (寒巌義尹, 1217–1300) was a disciple of Dōgen and the founder of the Higo school of Sōtō Zen Buddhism. It has been claimed that his father was Emperor Go-Toba or Emperor Juntoku. He did much evangelization work in Kyūshū, where he founded Daiji-ji (大慈寺) in Kumamoto. This temple has since been destroyed by fire twice, and nothing of Giin's remains there. He probably studied in China, but all extant biographies of him are hagiography so it is impossible to be certain.
A Shukokai Karate Kata was named after him (Giin)
