Born in Nagano Prefecture, Japan, in 1947. MA, Graduate School of Aichi University of the Arts. Toya started his artistic career with his attempt to reconstruct sculpture as a medium, which had been deconstructed by the preceding art movements such as postminimalism and mono-ha. Since the 1970s, the artist has diligently pursued the principles and structures of sculpture, which resonate with the epistemological foundations of our very existence, underscoring their essence and possibility through his artmaking practice. By manipulating various art histories of all times and places, encompassing the period of cave paintings and Greco-Roman sculptures to contemporary art, with his bona fide sculptural philosophy, Toya has been recognized as one of the leading sculptors in Japan, Asia and the Pacific at large.
