Arakaki Seishō (新垣 世璋, 1840–1918) was a prominent Okinawan martial artist and master of Tōde who influenced the development of several major karate styles.

[3] He was an official in the royal court of Ryūkyū, and as such held the title of Chikudon Peichin,[2] which denoted a status similar to that of the samurai in Japan.

[1] On 24 March 1867, he demonstrated Okinawan martial arts in Shuri, then capital of the Ryūkyū Kingdom, before a visiting Chinese ambassador; this was a notable event, since experts such as Ankō Asato, Ankō Itosu, and Matsumura Sōkon were still active at that time.

[2][3] His only recorded martial arts instructor from this period was Wai Xinxian from Fuzhou, a city in the Fujian province of Qing dynasty China.

[2][3] Arakaki was famous for teaching the kata (patterns) Unshu, Seisan, Shihohai, Sōchin, Niseishi, Shisōchin and Sanchin (which were later incorporated into different styles of karate), and weapons kata Arakaki-no-kun, Arakaki-no-sai, and Sesoku-no-kun.
