Akari 55D is a pendant lamp from Vitra designed by the Japanese-American artist and architect Isamu Noguchi in 1951. The lamp is made of shoji paper, paper made from the bark of mulberry trees, and is held up by a steel wire structure. Akari 55D is part of the Akari lamp series, a series of lamps designed by Noguchi and hand-made by Japanese craftsmen. In Noguchi's work artistically linked to abstract expressionism and his design language came to have a great influence on the design of the 1950s.
