In 1968, he obtained a degree in Fine Arts from Tama Art University, where he studied under influential abstract sculptor Yoshishige Saito, as well as surrealist and minimalist artist Jiro Takamatsu. After graduating, he became a prominent figure in the Mono-ha movement, actively participating in international art exhibitions.

It has had a significant and lasting influence on the development of Land Art, Installation Art, and Minimalism in Asia.
