Japanese karate

is one of the four major karate styles and was founded by Hironori Ōtsuka (1892–1982). Ōtsuka was a Menkyo Kaiden licensed Shindō Yōshin-ryū practitioner of Tatsusaburo Nakayama and a student of Yōshin-ryū prior to meeting the Okinawan karate master Gichin Funakoshi. After having learned from Funakoshi, and after their split, with Okinawan masters such as Kenwa Mabuni and Motobu Chōki, Ōtsuka merged Shindō Yōshin-ryū with Okinawan karate. The result of Ōtsuka's efforts is Wadō-ryū Karate.
