Kan Ishii(石井歓,Ishii Kan?, 30 March 1921 in Tokyo, Japan – 24 November 2009 in Yokohama, Japan) was a Japanesecomposer, and the brother of composer Maki Ishii. His father, Bac Ishii (石井漠,Ishii Baku?, 1886–1962) was a prominent Japanese ballet dancer. His Symphonia Ainu won a prize at the 1958 Art Festival, inspiring him to do further work inspired by nationalist primitivism. His musical style appeals directly to the emotions, and shows the influence of Carl Orff. In addition to orchestral and vocal music, he has written extensively for the stage, including 6 operas, 3 ballets and 9 film scores, including the 1962 science-fiction film Gorath. Ishii accepted a position as professor at Shōwa College of Music in 1986.
