Born 1947 in Komatsu (Ishikawa Prefecture). Mostly an autodidact, Moon was active in the Kansai area of Japan since the late 1960s. He participated in the 21st Gutai group exhibition of 1968, and the 5th International Young Art Exhibition of 1969. Until then, he used the name of “Noboru Fujino,” but changed it to “Moon Seung-Keun” in 1971. After the end of the Gutai group, Moon stayed active in and around Osaka, Kyoto, and Kobe and participated in national and international group exhibitions.

Between the 1970s, when the Mono-ha movement rose to popularity in Tokyo, and the Kansai New Wave of the 1980s, Moon worked in a variety of techniques that included oil painting, watercolors, print, three-dimensional objects, photography and video. He died from an inflammation of the gall-bladder in 1982. His paintings of layered watercolors and prints that take snapshots of urban landscape as a starting point, as well as oil paintings and objects he produced since the mid-1970s display Moon’s critical sensibility and a high degree of technical accomplishment. The Kyoto National Museum of Modern Art and the Chiba City Museum held the exhibition “Moon Seung-Keun and Tadashi Yagi: 1973-83” in 2007.
