work. The nine Spatial Poems were published together in a booklet in 1975. From 1965 to 1970 Mieko Shiomi lived in Tokyo and taught piano. Sometime between 1967 and '69 she changed her given name from Chieko to Mieko in accordance with Japanese onomancy (seimei handan), a shift reflected in some of the Fluxus editions from the late 1960s and early 1970s. Upon her return to Japan, Shiomi reconnected with members of the Japanese avant-garde, and remained active in the Tokyo art and music scene until her marriage in 1970. Her activities were particularly important for the development of the genre of intermedia in the late 1960s, as evidenced by her participation in key intermedia events including From Space to Environment and Cross Talk/Intermedia. 1970s to Today Upon her marriage in 1970, however, Shiomi's ability to travel regularly for rehearsals and performances was severely limited. She shifted her activities to what she could accomplish from her base of operations in Minoo, Osaka, completing much of the Spatial Poem series between 1970 and 1975. Music historian Miki Kaneda has described Shiomi's strategy of this time as a covertly feminist one, aimed at appropriating domestic technologies, such as the postal system, and adapting them toward her performative ends rather than breaking the constricting structures of the patriarchial order that chained her to the home. In Kaneda's words, "Shiomi’s Spatial Poems are a ‘submission to the inconvenience of the situation’, but also a performative intervention into the ‘distribution of the sensible’ of her immediate surroundings." After 1977, she returned to work on her own compositions but continued her links with Fluxus, including organizing the Fluxus Media Opera in Kobe in 1995 and participating in events and exhibitions that re-examined the legacies of Fluxus in the 1990s, 2000s, and 2010s. Once her children reached adulthood in the 1990s, she has become more active, starting with a Fluxus Balance mail art collaboration series initiated in the early 1990s. She has also experimented more with electronic technology since the 1990s, most notably dealing with telephones and computer synthesized voices in the series of Fluxus Media Operas she produced from 1992 to 2001. Shiomi remains active, performing both older works and developing new artworks and performances, including collaborations. She currently lives and works in Minoo, Osaka.
