Another student of Matsumora, Maeda Pechin, is credited with teaching Kyan the kata Wanshu.
[2] Kosaku Matsumora became famous at the age of 20 when he stole a sword out of the hands of an angry Satsuma overlord using only a "wet towel" as a weapon.
[3] Matsumora quickly revealed the moist Japanese towel which he had recently developed a habit of carrying concealed inside his garment.
[clarification needed][4] Matsumora hit the astonished samurai with the wet towel and grabbed the sword.
This event was so insulting to the Japanese overlords that Matsumora became an Okinawan folk hero overnight.
