Meifu Shinkage-ryû includes several specialized weapon skills that can be traced to the ancient Samurai in Japan. Many of the weapon skills taught in Meifu Shinkage-ryû were once kept as secret or hidden techniques, only taught to more advanced students of traditional schools such as Katori Shinto-ryû.
Meifu Shinkage-ryû teaches skills using Bo-Shuriken (棒手裏剣). Such throwing spikes are made of 14 to 15cm long square bar steel, and are 6 to 7mm wide. The official MSR Bo-shuriken were designed by Someya-Sensei.
The Fundo Kusari (分銅鎖) is the second major weapon taught in Meifu Shinkage-ryû. A safety Fundo Kusari, made of a plastic chain and a soft “weight”, is used to teach novice practitioners in a safe manner.
