In 1761, the military attache, Kusanku, was send to Ryukyu. By now, the martial arts had gradually become less secretive. Kusanku gave demonstrations of punching, kicking, blocks, and some high jumps from Northern Chinese styles. Originally, Southern Chinese Chuan-fa Kung-fu was mostly hand techniques and they did have some low kicks. The Okinawans ,as farmers on a rocky island, developed arms and legs that were very strong. Working barefoot, their feet were very tough and calloused, making them almost impervious to pain. These demonstrations excited the young men of Okinawa and motivated them to learn all these new techniques.
Years later, Tode Sakagawa came to train under Kusanku. When training under Kusanku was no longer available, Sakagawa sought out Peichin Takahara. Takahara was a well-respected warrior of the then common Ryukyu art of Tode (China hand). Tode was the pronunciation of the Chinese name at that time of T'ang for the T'ang Dynasty. The Shaolin martial arts reached their halcyon during the T'ang dynasty, 618-906 A.D. Hence, known as T'ang hand, later in Japanese, the T'ang character could also be pronounced as kara, i.e. kara te.
Sakagawa's mastery of this art was so revered and respected, he was renamed "Karate" Sakagawa. He was also allowed to train under a Chinese adherent, Kung Syang, in Chuan-fa Kung-fu. These teachers were both very old, so the eager and capable young practitioners created many different techniques out of his foundations. Martial arts masters and practioners have always used their training and imagination to develop new and creative moves. Each one would jealously protect "his" ideas, and this is how different ryu (schools or styles) would start to come about. Sakagawa traveled to China several times to study the various branches of the Shaolin style. (In Japanese, it would translate to Shorin-ryu). By now, much of the philosophical nature the original Shaolin spirit of Bodhidharma's Chan (Zen) and Taoism (DO) had been lost, or at least , not completely understood.
Special Note: The Zen philosophy had been taken to Japan separately in the 1200's by a Zen Master named Doshin. Later, the Do, the Way of Zen, would be added to martial arts and adopted by the samurai as the Code of Bushido. Bushido means the Way (Zen influence) of the Bushi (warrior).
