Overview
Nobuo Sekine (関根伸夫; 1942–2019) was a Japanese sculptor best known for his role in the Mono-ha movement of the late 1960s and 1970s. His practice drew attention for treating natural and industrial materials as primary carriers of meaning, and for making the relationships between objects, site and viewer central to the work. Sekine is widely remembered for a single, decisive work that crystallized many ideas of his circle and reached audiences both inside and beyond Japan.
Artistic approach and characteristics
Sekine and his Mono-ha colleagues emphasized raw materials—stone, wood, earth, metal, and industrial products—arranged with minimal manipulation so that material qualities and spatial relations became the subject of perception. Rather than carving or composing in the classical sense, Sekine often worked by displacing or juxtaposing matter to reveal contrasts of texture, weight, color and presence. His pieces frequently explore negative space, site specificity and the tension between permanence and ephemerality.
Phase: Mother Earth (1968)
In October 1968 Sekine executed Phase: Mother Earth for the First Open Air Contemporary Sculpture Exhibition in Kobe’s Suma Rikyu Park. The work consisted of a formed mass of earth set beside the hole from which that earth had been taken, inviting viewers to regard presence and absence as two halves of a single event. The piece became emblematic of Mono-ha’s concerns by foregrounding process, matter and the viewer’s act of looking. It has since been discussed, re-staged and exhibited in different contexts as a key moment in postwar Japanese sculpture.
Other work, exhibitions and influence
Throughout his career Sekine produced objects and installations that continued to interrogate material relations and spatial experience. His sculpture practices influenced younger generations in Japan and contributed to international conversations about minimalism, conceptual art and ecological approaches to making. While closely associated with a specific historical moment, his work is often cited for its ongoing relevance to debates about environment, site and the ontology of the sculptural object.
Biographical notes and legacy
Nobuo Sekine was born in Saitama, Japan, on September 19, 1942. He remained an active presence in art circles for decades, and his best known works continue to be studied and shown. Sekine died on May 13, 2019 in Los Angeles, California at the age of 76. Today he is remembered as a central figure of Mono-ha whose careful use of materials shifted how sculpture could relate to place, time and perception.
