Meifu Shinkage-ryû (MSR) is a modern school of Japanese martial arts. It was developed out of Tenshin Shoden Katori Shinto Ryu by Someya Chikatoshi. MSR provides specialized instruction teaching techniques using throwing spikes and blades (shuriken jutsu), a weighted chain (Fundo Kusari Jutsu), as well as techniques using many other hidden weapons (Kakushi Buki Jutsu). It were the samurai and ninja of medieval Japan who were believed to be master in using these techniques while in combat.
Yasuyuki Otsuka-Sensei is the current Head Master (Soke) of Meifu Shinkage Ryu since 20009. He is the second Soke, after the founder and first Soke (Chikatoshi Someya-Sensei) passed away in 1999. Otsuka-Sensei became Soke in 2006.
Like any martial arts teaching armed skills such as Kendo (sword fencing), Kyudo (Archery), and Kobudo (staffs and other tools), the techniques are taught to provide the participant with an understanding how armed combat took place many years ago. In addition, the way of modern budo (Gendai Budo) allows practitioners to develop a philosophical and spiritual approach when trying to achieve mastery of the techniques.
