Okajima Kanzan
Okajima Kanzan was a scholar and teacher of Chinese language and calligraphy, known for compiling the first Japanese dictionary of vernacular Chinese in 1716.
Okajima came from a hereditary family of Nagasaki-based Chinese-language interpreters. He left that vocation to pursue a different life in Edo, and ended up becoming a notable contributor to Ogyû Sorai's Chinese-language association. In 1716, he compiled the Tôwa san'yô, a dictionary of spoken Chinese.
