Tōon-ryū (東恩流, Tō'on-ryū) is a style of Okinawan Karate founded by Kyoda Juhatsu.

Kanzaki gave teaching licenses to Yoshino Jusei (重正) (1937–2017), Fujishima Jusho (重捷), and Ikeda Jushu (重秀).

Ikeda Jushu is the current Yondai Soke of Tōon-ryū (4th generation head of the school) still teaches karate in Beppu, Ōita.

Information about Tōon-ryū in the Western world appears mainly due to the efforts of the Karate researcher Pavel Demyanov (Russia).

Pavel Demyanov studied under Ikeda Jushu (Shigehide) and learned the entire Tōon-ryū curriculum, including Kobudo, and has permission to teach.
