Kangan Giin (寒巌義尹, 1217–1300) was a disciple of Dōgen and the founder of the Higo school of Sōtō Zen Buddhism.

He did much evangelization work in Kyūshū, where he founded Daiji-ji (大慈寺) in Kumamoto.

[1] Before practicing with Dōgen, Giin started his Buddhist path as a Tendai monk.

Giin asked Wuwai Yiyuan, a primary student of Rujing, to write a foreword for the collection as well as to edit it.

After returning from China, Giin practiced at a temple called Shōfuku-ji in Kyushu connected to Myōan Eisai.
