Since the 1960s, his work has been defined by a signature “rainbow” visual language - an exploration of colour as both image and sensory experience. Expanding the boundaries of painting and printmaking, these compositions are at once immediate and immersive, reflecting the experimental ethos of Fluxus while maintaining a striking visual clarity.

Balancing conceptual grounding with accessibility, the works occupy a unique position within postwar Japanese art - at once historically significant and visually direct, with a presence that continues to resonate across contexts and audiences.
