Masahiko Satoh (佐藤 允彦 Satō Masahiko, born 6 October 1941) is a Japanese jazz pianist, composer and arranger.

At the age of 26, Satoh moved to the United States to study at the Berklee College of Music. He stayed for two years, during which he read about composing and arranging. He earned money working in a food shop and playing the piano in a hotel. In 1968 he wrote the music for, and conducted, a series of pieces that were combined with dance and performed in New York. After returning to Japan, he recorded Palladium, his first album as leader, and appeared on a Helen Merrill album.

In his early career in the late 1960s and early 1970s, Satoh played in a free, percussive style. Satoh played at the 1971 Berlin Jazz Festival as part of a trio; he used a then-unusual ring modulator to alter the sound. Also in the early 1970s, he recorded with Attila Zoller, Karl Berger, and Albert Mangelsdorff. He wrote the psychedelic music for the 1973 anime film Belladonna of Sadness...[more]
