He is, along with Cho Chikun, Kobayashi Koichi, Otake Hideo, Takemiya Masaki and Kato Masao, considered one of the 'Six Supers' who dominated the Japanese Go world in the last three decades of the twentieth century.

Rin Kaiho was born in Shanghai, China and moved to Taiwan after the second world war.

Rin's rise to fame came in 1965 when he challenged Sakata Eio for his Meijin title.

Rin has been on a dry spell of titles lately, with the last time he even challenged for one being in 2001, for the Meijin.
