Ay-O

Ay-O (靉嘔, born 1931) is a Japanese artist and printmaker internationally recognized for his exuberant rainbow-themed works that span printmaking, painting, sculpture, and performance art. A member of the Fluxus movement and a longtime resident of New York, Ay-O has built a career around the systematic exploration of the visible spectrum, creating prints and artworks in which rainbow gradations of color become both subject and medium. His work bridges Japanese printmaking traditions and Western avant-garde practice, making him one of the most internationally connected Japanese artists of his generation.

Born Takao Iijima in 1931 in Ibaraki Prefecture, Japan, the artist adopted the pseudonym Ay-O early in his career. He studied art in Tokyo and became associated with the Demokrato Artists Association, an avant-garde group that challenged the conventions of the Japanese art establishment. In 1958, seeking broader artistic horizons, he moved to New York City, where he quickly became involved with the downtown Manhattan art scene and the emerging Fluxus movement.

Fluxus, the international network of avant-garde artists founded by George Maciunas, emphasized intermedia experimentation, anti-commercialism, and the dissolution of boundaries between art and everyday life. Ay-O became an active participant, contributing to Fluxus events, publications, and exhibitions alongside artists such as Yoko Ono, Nam June Paik, George Brecht, and Alison Knowles. His "Tactile Boxes" — small containers with finger holes through which viewers could touch unseen objects — became one of the most celebrated Fluxus works, playfully challenging the visual primacy of conventional art.

Ay-O's artistic identity crystallized around the rainbow, which he adopted as his defining motif in the early 1960s. From that point forward, virtually all of his work has incorporated rainbow color gradations — systematic progressions through the visible spectrum from red through orange, yellow, green, blue, and violet. He has applied this rainbow principle to an extraordinary range of media and contexts: silkscreen prints, woodblock prints, paintings, sculptures, environments, furniture, clothing, pianos, and even an entire room. His "Rainbow Room" installations immerse visitors in floor-to-ceiling rainbow environments that transform the experience of color from visual observation to full-body sensation.

As a printmaker, Ay-O has been prolific and technically versatile. He works in both silkscreen and woodblock techniques, often combining them. His rainbow silkscreens translate well-known images — including reinterpretations of masterworks by Hokusai, Da Vinci, and other canonical artists — into his signature rainbow palette, creating works that are simultaneously homage and transformation. His woodblock prints demonstrate skilled carving and printing technique applied to the rainbow theme, connecting his avant-garde practice to the traditional Japanese medium.
