The founder of Wadō-ryū, Hironori Ōtsuka, was born on 1 June 1892 in Shimodate, Ibaraki Prefecture, Japan. In 1898, Ōtsuka began practicing "koryū jujutsu" under Chojiro Ebashi. From 1905–1921, he studied Shindō Yōshin-ryū jujutsu under Tatsusaburo Nakayama. In 1922, he met Gichin Funakoshi and began to train under him. In 1924, Ōtsuka became one of the first students promoted to black belt in karate by Funakoshi. To broaden his knowledge of Karate, Ōtsuka also studied with other prominent masters such as Kenwa Mabuni of Shitō-ryū and Motobu Chōki. In 1929, Ōtsuka organized the first school karate club at Tokyo University. Eiichi Eriguchi coined the term 'Wadō-ryū' in 1934.
