Yamanni Ryu Kobudo

Yamanni-ryu (also Yamanni-Chinen-ryu and Yamane Ryu) is a form of Okinawan kobudo 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 Sakugawa SATUNUSHI, entrusted with the protection of prominent Ryukyu families, had studied the art in China. Later he lived in Akata village in Shuri, Okinawa. Sakugawa developed the style in the late 1700s. He passed it on to the Chinen family, beginning with Chinen Umikana. Sanda Chinen (1842-1925), also known as Yamani USUMEI and Yamane TANMEI, introduced the "bouncing" motion of the staff which is the style's hallmark. His grandson, Masami Chinen, named the style after him.

Ryukyu Bujutsu Kenkyu Doyukai

In 1979 Chogi Kishaba, a student of Masami Chinen, sent his 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. Kishaba is the head of the RBKD. Shihan Oshiro (8th dan, Yamanni-ryu; 9th dan, Shorin-ryu) is the Chief Instructor of RBKD USA and its West Coast Director. The Midwest Director is Kiyoshi Nishime. Oshiro gives seminars in Yamanni-ryu in the U.S. and around the world.

The Yamanni-ryu patch is based on an Okinawan mon. It is similar to the mon of the Takeda clan.

Yammani-ryu is a fluid style that is frequently taught to advanced students. Occasionally it is taught as a supplementary style to other Okinawan kobudo, such Kenshin-ryu. Students of Shotokan and Shito-ryu karate will frequently learn Yammani-ryu kobudo, either through their own sensei or via seminars held by Shihan Oshiro both at his home dojo and abroad.
