Plane and shape are the nucleus of s work. His work is influenced by traditional Japanese motifs and incorporates grid structures and vibrant planes of color that explore warm/cool contrast, close-valued color, and analogous color ranges. In the 1974 poster for Senei Ikenobo s flower arrangements, mountains and waves are created by a rhythmic sequence of blue and blue-green bands under a graduated tan sky. His 1981 Nihon Buyo poster for the Asian Performing Arts Institute uses planes of color on a twelve-unit grid to define the abstracted and expressive portrait.
