Below is a letter written by Itosu Sensei in October of 1908. This letter preceded the introduction of karate to Okinawan schools and eventually to the Japanese mainland.
Tode did not develop from the way of Buddhism or Confucianism. In the recent past Shorin-ryu and Shorei-ryu were brought over from China. They both have similar strong points, so, before there are too many changes, I should like to write these down.
