Yasuji Kiyose (?? ?? Kiyose Yasuji, 13 January 1900 โ 14 September 1981) was a Japanese composer.
He studied composition privately with Kosaku Yamada and Kosuke Komatsu and in 1930, took an active part in organizing the Shinko Sakkyokuka Renmei, (which later grew into the Japanese section of the ISCM).In 1948, Kiyose took on Hiroyoshi Suzuki and Toru Takemitsu for a brief period as pupils in composition.His music at times incorporates Japanese pentatonic scales, and other elements of Japanese folk-song; his far better known pupil Takemitsu, developed this tendency further in a great number of his works.
