By 1959 Satoh was playing in Georgie Kawaguchi's band, together with alto saxophonist
Sadao Watanabe and tenor saxophonist
Akira Miyazawa. 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. After returning to Japan, he recorded
Palladium, his first album as leader, and appeared on a
Helen Merrill album. Satoh has written arrangements for recordings led by, among others, Merrill,
Kimiko Itoh, and
Nancy Wilson. He also arranged for strings and quartet on
Art Farmer's 1983 album
Maiden Voyage. In 1990 Satoh formed a large group, named Rantooga, that combined various forms of folk musics from around the world. In the early 1990s he composed music for a choir of 1,000 Buddhist monks. In the early 1990s he was reported as stating that 70% of his time was spent on arranging and composing, and the rest on playing and recording. ==Compositions==
