Yamanni Chinen-ryū Kobujutsu • 山根知念流古武術

Yamanni Chinen-ryū is a classical martial tradition rooted in the art of Okinawan bōjutsu. Its primary weapon is a cylindrical bō measuring approximately 1 inch in diameter and 6 feet long. The kata of Yamanni-ryū are characterized by powerful and fluid motions, giving the impression that the bō is bouncing dynamically. Alongside the bō, extensive practice is devoted to the sai, a three-pronged truncheon. Additional secondary weapons such as the tonfa, kama, and nunchaku are also utilized.

Yamanni-ryū is a lesser-known style that has retained its classical essence and remains relatively unaffected by modernization. According to tradition, Sakugawa "Tōdi" Kanga (1733-1815) introduced this art from China to Okinawa in 1762. It was then passed down through three generations of the Chinen family before reaching Kishaba Chōgi Sensei (1934-2017) and eventually Oshiro Toshihiro. Yamanni-ryū employs advanced body mechanics and centerline theory, distinguishing it from today’s more commonplace karate styles. It offers valuable insights into the original movements and techniques of both armed and empty-handed martial arts within Okinawa, making it suitable for practitioners of all experience levels.

Bōjutsu refers to the techniques associated explicitly with the bō, including swinging, slashing, and thrusting.

Saijutsu refers to the techniques of the sai, which are three-pronged metal truncheons often wielded in pairs.
