Rin Kaihō or Lin Haifeng (Chinese: 林海峰; pinyin: Lín Hǎifēng; born May 6, 1942) is a professional Taiwanese ^{[citation needed]} Go player who made his name in Japan. 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. He learned go from his older brother, and later was a student of Go Seigen when Go brought him to Japan in 1952.^[1] He was a promising player who won his first title at the age of 23, the Meijin. He is also part of the 1200 win group. Rin's rise to fame came in 1965 when he challenged Sakata Eio for his Meijin title. Rin, at the time, was still only 23 and critics thought he would stand no chance against the then powerful Sakata. Even Sakata himself said that no Go player under the age of thirty should be Meijin. However, Rin put up a great fight and won the Meijin title. Rin would continue winning the Meijin on different occasions, along with the Honinbo, during the late 1960s and early 1970s. His number of titles currently is 34, ranking him 7th of all time on the total number of titles list, tied with Norimoto Yoda. 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. Rin became the first professional in Nihon Ki-in history to reach 1,300 career wins. He won the game against Nobuaki Anzai on October 19, 2006 in a preliminary match for the 32nd Kisei.^[2] Rin currently resides in Tokyo, Japan, but remains a citizen of Taiwan.
