Yoshio Ishida

Yoshio Ishida (石田 芳夫, Ishida Yoshio; born August 15, 1948) is a professional Go player and author of several books on Go.^[1]

By the time he was 8, Ishida started learning Go. He was a student at the legendary Kitani Minoru go school. Famous along with his fellow students Cho Chikun, Kobayashi Koichi, Kato Masao, and Takemiya Masaki. He joined the dojo at a young age like his fellow students. He became a professional in 1963 when he was 15. His dan rank grew quickly because of the Oteai. He would go up the ranks faster than rules allowed after winning the first 14 Oteai games when he was being promoted from 6 to 7 dan. He reached 9 dan in 11 years, faster than most other players do. Ishida was given the nickname "The Computer" because his Yose play and counting skills were far more accurate than other pros.

Ranks #9-t in total number of titles in Japan.

• Medal with Purple Ribbon (2016)
