Sori Yanagi Rosewood Butterfly Stool

Consisting of two gracefully curving and identical molded plywood shells that recall butterfly wings and are fastened together by a single brass crossbar, the Butterfly stool by Sori Yanagi (1915–2011) is the most acute mid-century merging of Eastern and Western sensibilities.

When he introduced the structured chair to a market that had until then been defined by tatami mats, Yanagi upended Japanese tradition. But the Tokyo-born furniture designer, who created the all-plastic Elephant stool during the same year in 1954, demonstrated reverence for the past with his piece, too: The chair’s two inverted, L-shaped plywood components, constructed by molding methods made popular by forward-looking American designers Charles and Ray Eames, have been compared to calligraphic forms and resemble the regal, spare torii gates that serve as entrances to Shinto shrines and Buddhist temples, bringing together the sacred and mundane worlds.

The son of Soetsu Yanagi — the founder of Mingei, the Japanese folk art movement — Sori studied painting and architecture, and later worked for French architect-designer Charlotte Perriand when she was appointed an arts and crafts advisor to the Japanese Board of Trade in 1940. Yanagi became her travel companion in Japan, learning about European modernism and French design, and eventually switched his focus from architecture to design. As a product designer, he was immensely prolific and worked steadily until his death in 2011. Yanagi’s wide range of items, from Sony’s early “H Type” tape recorder (1951) to children’s toys to pedestrian bridges to a best-selling stainless-steel teakettle, more than half a million of which are sold yearly in Japan, defined postwar Japanese society. His products are both practical and distinctly modern, and are characterized by an affinity for both new shapes and simple, functional forms. As a designer, Yanagi’s modernist focus on efficiency and structure yielded a legacy of creative pieces that not only struck a nerve in Japan, but defined its postwar society as well.

The Butterfly stool, an early-career design first manufactured by Tendo Mokko, has remained in production since the 1950s — it’s currently available from Vitra in maple and rosewood. Soon after it debuted, the stool won the Gold Medal at the Milan Triennale of 1957 and later entered the permanent collections of the Museum of Modern Art, the Metropolitan Museum of Art and elsewhere. Simple and sculptural, the Butterfly stool is Yanagi’s most celebrated and well-received piece of furniture.

Sōri Yanagi was a Japanese product designer. Born in 1915 in Tokyo, Japan. His father was Yanagi Sōetsu, founder of the Japanese folk crafts mingei movement, which celebrated the beauty of everyday objects, and the Japanese Folk Crafts Museum (Nihon Mingeikan). Yanagi entered Tokyo Art School in 1934, where he studied both art and architecture. He played a role in the Japanese modern design developed after the Second World War to the high-growth period in the Japanese economy. Yanagi was both a representative of the wholly Japanese modern designer and a full-blown Modernist, who merged simplicity and practicality with elements of traditional Japanese crafts. He designed the official torch for the 1972 Winter Olympics in Sapporo, Japan. Yanagi died in 2011 at the age of 96.
