Michio Miyagi (1894–1956) was a prolific Japanese musician and composer, revered for his mastery and innovations within the realm of koto music. Born in Kobe, he was blinded in an accident as a young child but found his calling in music, taking up the koto and shakuhachi. Over his lifetime, Miyagi transformed the landscape of traditional Japanese music, incorporating Western elements and expanding the scope of what was considered possible on the koto, a traditional 13-stringed instrument.

His most famous piece, "Haru no Umi" (The Sea in Spring), has become an iconic work, capturing the essence of Japanese musical aesthetics. Miyagi's dedication and virtuosity led to the expansion of the koto's repertoire and capabilities, including the development of new playing techniques and the designing of a 17-string bass koto. His music, as captured on albums such as "Koto Legends, Vol. 1" and "The Koto Music of Michio Miyagi," showcases his life's work and leaves a lasting legacy that continues to inspire koto players and admirers of traditional Japanese music around the world.
