The mysterious Kusanku of a Chinese envoy settled in Okinawa for some time.His most famous student was Satunuku "Tode" Sakugawa (1733-1815). It is believed Sakugawa became a student of Kusanku in 1756. Sakugawa was a student of Takahara Peichin (1683-1760) (Peichin is a title of status) until the arrival of Kusanku in Okinawa. At that time Sakugawa was granted permission from Takahara Peichin to train under Kusanku.

Sakugawa traveled to China with Kusanku to study Kempo. He returned to Okinawa in 1762 to introduce this fighting method. Before long Sakugawa was considered an expert in the Chinese hand fighting method. It is said that Sakugawa was awarded the title of Satonushi for his services to the Okinawa King.

Sakugawa soon started to teach the Chinese hand way in Okinawa. Combining what both his teachers had taught him, he structured a training system. This made him the first Okinawan teacher of Tode. Many of his students rose to greatness. Among them were Chokun Satunku Macabe, Satunuku Ukuda, Chikuntonoshinunjo Matsumoto, Kojo, Yamaguchi ("Bushi" Sakumoto), Unsume, and Sokon "Bushi" Chikatosinumjo Matsumura.

It would be Sakagawa's student, Sokon Bushi Matsumura, who would be considered the forefather of many Karate styles.
