Meifu Shinkage-ryu includes several specialized weapon skills that can be traced to the ancient Samurai in Japan. Many of the weapon skills taught in Meifu Shinkage-ryu were once kept as secret or hidden techniques, only taught to more advanced students of traditional schools such as Katori Shinto-ryu.
Meifu Shinkage-ryu teaches skills using Bo-Shuriken (stick shuriken). 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 (the chain weight) is the second major weapon taught in Meifu Shinkage-ryu. A safety Fundo Kusari, made of a plastic chain and a soft weight, is used to teach novice practitioners in a safe manner.
