(b.1958) Nihon Ki-in pro, 9 dan in 1985.
Miyagawa Fumihiko was his pupil. Yamashiro grew up with Go, as he became a professional in 1972. He would eventually join the Nagoya branch of the Nihon Ki-in. He became a 9 dan in 1985 after winning the Okan. He has challenged for many of Japan's biggest titles (the 16th Kisei, 32nd Oza, 18th Tengen and 41st, 42nd and 48th Honinbo).
Yamashiro obtained 1,000 wins in his career on 2008-07-07, the tenth player of the Nihon Ki-in to have done so.
In 2010, Yamashiro won the 51st Okan for the 15th time (the Okan is the only title he's won).
Style: Rin Kaiho said in 1992 that Yamashiro's old style "was a steady, territorial player, but recently he sets up large moyos, and he's also flexible enough to switch from moyos to territory." (Tournament Go 1992)
