Ay-O

Ay-O was born Takao Iijima on 19 May 1931 in Ibaraki Prefecture, Japan. He joined the Demokrato Artists Association, led by Ei-Q, in 1953, and graduated in 1954 from Tokyo Kyoiku University (Tokyo University of Education, now the University of Tsukuba), in the Art Department of the Faculty of Education. He moved to the United States in 1958 and based himself primarily in New York, traveling between the US and Japan for much of his career. In New York he became part of the Fluxus milieu organized around George Maciunas, working alongside artists including Yoko Ono.

From 1964 he developed the Rainbow series, rendering the full color spectrum across paintings, prints, sculpture, and installation, and he became known for tactile, participatory works such as the Finger Box series. He represented Japan at the 33rd Venice Biennale in 1966 with a Rainbow Tactile Room, and showed a related installation at World Exposition '70 in Osaka. In 1987 he staged Rainbow Happening no. 17, suspending a 300-meter rainbow banner from the Eiffel Tower in Paris. According to Artsy, he stopped printmaking around 2017. Sources from 2023 and 2024 describe him as living in Japan, though accounts differ on whether his primary residence is Tokyo or Osaka; no death date has been reported by any source consulted for this profile.

Recent institutional programming has centered on reintroducing Ay-O to audiences outside Japan. The Smithsonian's National Museum of Asian Art organized Ay-O's Happy Rainbow Hell (2023), his first solo museum exhibition in the United States, drawing largely from the museum's own holdings. M+ in Hong Kong presented Ay-O: Hong Hong Hong, surveying work from the 1950s to the 2000s. No verbatim critic quotations from named writers in major outlets could be confirmed from available sources, so none are reproduced here.

Ay-O's auction record is Rainbow Sea-Scape (1970), which sold for USD 113,000 at Christie's Hong Kong on 28 May 2024, according to HENI's market reporting. That result exceeded his previous record of USD 103,800, set by Rainbow Landscape B (1964) at Sotheby's on 1 October 2018. His market activity spans many auction appearances, most of them prints, with sales concentrated in Japan and Hong Kong through Christie's, Sotheby's, and regional houses; price levels remain modest relative to his Fluxus contemporaries with broader Western market recognition.

No catalogue raisonne has been identified for Ay-O, and authentication currently runs through the artist's exhibiting galleries, Whitestone Gallery and Gallery Toki-no-Wasuremono, together with museum collection and exhibition records. His auction supply is thin and dominated by prints, so any single high result, including the 2024 Christie's record, should be read as an outlier rather than a stable market baseline. Given the conflicting reports on his current residence and the reduced pace of new work since around 2017, collectors should treat recent biographical details as provisional pending further confirmation.
