Michio Miyagi was a Japanese musician, famous for his koto playing.
He was born in Kobe. He lost his sight in 1902, when he was 8 years old, and started his study in koto under the guidance of Nakajima Kengyo II, dedicating the rest of his life to the instrument. In 1907 he moved with his family to Incheon, in southern Korea. When he was 14 years old, in 1909 he finished his first composition, Mizu no Hentai. At 18 he reached the rank of kengyo, the highest rank for a koto performer.
Miyagi moved to Tokyo in 1917, and in 1919 he did his first recital of his own compositions. In 1920, he took part in the Great Recital of the New Japanese Music with Seifu Yoshida and Nagayo Motoori. He was reckoned as an authority in the new Japanese music, achieving notability in the early Shōwa period. In 1925 he participated in one of the first radio presentations in Japan, and in 1929 he signed an exclusive contract with Victor Record Company, current JVC. He composed his most famous piece, Haru no Umi, in 1929.
In 1930 he became a lecturer at the Tokyo College of Music, until he was appointed professor in 1937. In 1932 French violinist Renée Chemet visited Japan on a concert tour.
