Yamanni-ryu (also Yamanni-Chinen-ryu) is a form of Okinawan kobud whose main weapon is the bo, a non-tapered, cylindrical staff. The smaller buki, such as sai, tunfa (or tonfa), nunchaku, and kama (weapon) are studied as secondary weapons. Tradition maintains that Kanga "Todi" Sakugawa, entrusted with the protection of prominent Ryukyu families, developed the style in the 1700s. He passed it on to the Chinen family, beginning with Chinen Umikana. Sanda "Yamanni" Chinen (1842-1925) introduced the "bouncing" motion of the staff which is today the style''s hallmark. His grandson, Masami Chinen, named the style after him. The current head, Chogi Kishaba, is Masami''s student. In 1979 he sent his premier student, Toshihiro Oshiro, to the United States. In 1985 they founded the Ryukyu Bujutsu Kenkyu Doyukai or RBKD (Association for the Study and Research of Okinawan Martial Arts) for the purpose of bringing Yamanni-ryu to the West.
