After a spell in his family's store, in 1941 he went to Tokyo, where he joined the Tokyo Symphony Orchestra as a hornist. In 1946 he became principal horn of the Japan Symphony Orchestra; in 1949 he resigned and returned to Osaka, where in 1950 he joined the Osaka Philharmonic Orchestra. Here he remained until 1966.
