Yamagishi is well versed in martial arts and trained in martial arts since childhood. At age 30 he was drafted into the military where he served on the front lines. After he completed his military service he moved with his wife to Sakuragaoka because his wife had a love of cherry trees.

At Suzume Park he offers to teach Ryo a move called Double Blow, a move that he once taught his father Iwao.
