Born in Yokohama in 1940, Hiroshi Yoshimura was a leading musician in environmental music in Japan. After graduating from Waseda University (Department of Arts), he studied composition by selfeducation. He made various creations combining the genres such as sound design, graphic design, sound objects and performances with the aim of “music as environment” and “music close to air”.

He worked on many sound designs for public spaces particularly in joint construction with TOA Corporation, such as Stereophonic Work at Yokohama Municipal Sports Park (Yokohama City, 1997) and Sound Sign in Kobe Municipal Coastline Subway (Kobe City, 2001). Also at museums, he gave many workshops with the theme of environmental sounds to the citizens. He was also a part-time lecturer at the Kunitachi College of Music (Department of Music Design) and Chiba University (Department of Industrial Design).

Although most of his work is left as sound designs for public space, and as a CD made by the sound of a synthesizer etc, there is only one collection for his piano work titled “Tranquility book” (Shunjusha Publishing Company, 2003) which includes musical scores for performing. He did not have a piano at his home, but he was adored the sound of the piano. This collection is full of respect for the sound of the piano and environmental sounds. It is his last book. In 2003, he passed away at the age of 63.
