Tōon-ryū (東恩流, Tōu'on-ryū) is a style of Okinawan Karate founded by Juhatsu Kyoda.
Juhatsu Kyoda (許田 重発, Kyoda Juhatsu, December 5, 1887–August 31, 1968) entered the dojo of Higaonna Kanryō in 1902 and continued studying with him until Kanryō's death in 1915. One month after Kyoda started, Miyagi Chōjun (co-founder of Gōjū-ryū) entered the dojo. In 1908, Kenwa Mabuni (founder of Shitō-ryū) also joined the dojo of Higaonna Kanryō.
In 1934 Kyoda received his Kyoshi license from the Dai Nippon Butoku Kai.
The Tōon-ryū kata and training drills consist of: Ten-I-Happo, Tsuki-Uke (Shiho-Uke), Kiso I & II, Sanchin, Sesan, Sanseru, Pechurin, Jion, & Nepai. Apparently Kyoda knew two versions of Seisan: one from Higaonna Kanryō and one from Higaonna Kanryu, but only passed on the Kanyu version. He learned Jion from Kentsū Yabu. By far Higaonna Kanryō had the most profound impact on him as Kyoda devoted well over a decade of his life to learning Kanryō’s karate. He ultimately named his style after him: Tō-on-ryū (literally ‘Higaon[na] style’).
"Tō-on" (唐音, lit. "Tang sound"), also pronounced "tō-in", are Japanese kanji readings imported from China by Zen monks and merchants during and after the Song dynasty. This period roughly corresponds with the mid-Heian to Edo Period of Japan. During the Muromachi period, they were referred to as "sō-on" (宋音, "Song sound"). Together, they are collectively known as "tōsō-on" (唐宋音).
Scholars divide tō-on into two groups: those that are based on Zen of the Middle Ages, and those based on the Obaku school of Buddhism of the Middle Ages. The latter are the readings sometimes referred to as "sō-on".
Tō-on readings are not systematic, as they were introduced piecemeal from China, often along with very specialized terminology.
Examples of words and characters using tō-on readings include: chair (椅子, isu), futon (蒲団), paper lantern (行灯, andon), Ming (明, min) and Qing (清, shin).
