KOSHIMIZU Susumu was born in 1944 in Ehime Prefecture, Japan. He graduated from Sculpture Department, Tama Art University and later became one of the key members of Mono-ha, a group of artists who turned prominent in the late 1960s and 1970s. From early on, Koshimizu’s investigation of material and space resulted in some of Mono-ha’s most definitive artworks. Koshimizu’s installations and sculptures during the 1960s and 1970s focused on the qualities inherent to but not visible in an object. He shows concern for the materiality of objects—a desire to expose the fundamentals of sculpture, often revealed through juxtaposition. At the beginning of the 1970s, Koshimizu started to explore specifically the structure of surfaces. He produces works which highlight the relationships between materials, or ones that questions the true nature of art by using the ordinary materials estranged from their usual usages.
