Born 1941. His worldwide activities as a pioneering figure in the realm of sound art since the early 1960s have been revolving around “listening” as a central aspect. Built the echo instrument Analapos in 1970. In 1988, he set up the “Hinatabokko no kukan (Space in the Sun)” for listening to the sounds of nature over the course of a day in Amino-cho (now Kyotango) in Kyoto, a place located exactly on the meridian line. Unveiled “Otodate (Echo point),” a painted ear looking like a footprint on the ground, on which one can stand and listen to the sounds of that particular location, in 1996. Has been invited to major art shows and music festivals in Europe and around the world.
