Hiroshi Yoshimura was a Japanese musician and composer. He is considered a pioneer of ambient music in Japan. His music lies mostly in the minimalist genre of kankyō ongaku, or environment music-soft electronic melodies infused with the sounds of nature: babbling brooks, steady rain, and morning birds. However, not all Yoshimura's work included nature sounds. His album Green only contained them in the United States release, as they were excluded in the Japanese version.
