First of all, Sokon Matsumura was not knwon as Miyamoto Musashi. He was sometimes reffered to as “The Miyamoto Musashi of Okinawa” Musashi was an entirley different person, a samurai of Japan.
Also, a bit of history, Shorin-Ryu kata was developed as a system of communication and defense. Since the Japanese forbid the Okinawans from meeting in groups, the Okinawans developed kata. A Okinawan could meet another on the road, tech him a kata and be gone.
One more thing. True, Shorin-Ryu does weapons, but in the time they developed, the Bo, Nunchaku, Sai and Kama were just farm tools, as their “traditional” weapons had been confinscated.
