Jikken Kōbō [Experimental Workshop] was a cross-disciplinary, intermedia art collective active in 1951-57 in Tokyo. For many, the group signaled the rebirth of avant-garde art in postwar Japan.
Jikken Kōbō consisted of fourteen members: the painters Shōzō Kitadai (1923–2001), Hideko Fukushima (1927–1997), and Katsuhiro Yamaguchi (b. 1928); the printmaker Tetsurō Komai (1920–1976); the composers Kazuo Fukushima (b. 1930), Keijirō Satō (1927–2009), Hiroyoshi Suzuki (1931–2006), Tōru Takemitsu (1930–1996), and Jōji Yuasa (b. 1927); the poet and critic Kuniharu Akiyama (1929–1996); the photographer Kiyoji Ōtsuji (1923–2001); the lighting designer Naoji Imai (b. 1928); the pianist Takahiro Sonoda (1928–2004); and the engineer Hideo Yamazaki (1920–1979).
From 1951 to late 1957 Jikken Kōbō created a series of works in collaboration with people outside the group and from a variety of creative fields, including the acclaimed modern dancers Takashi Masuda and Momoko Tani, the avant-garde film director Toshio Matsumoto, and the actress Kyōko Kishida. The group also created audiovisual work using a slide projector synchronized with a magnetic tape recorder, with the help of technicians who later named their company Sony. (Source)
