His students included Kanken Toyama and Gima Shinkin.

      “On the other hand, Dave Lowry has written that Yabu's teacher was Yasutsune "Ankoh" Itosu (Lowry, 1985, 11). Because both Matsumura and Itosu were well-known karate teachers of the day, probably Yabu studied with both men at different times.”
