Kosuke's work is mixed with philosophical and anthropological sense, as well as the influence of conceptual art, avant-garde, and the Japanese sense of “zen”. Because a lot of concepts are mixed, his work emphasizes spirituality and meaning rather than the retinal perspective of painting in general. He considers creation and appreciation of art as a “ceremony of confirmation” which lead the theme of his work as “The truth for the human being”. Kosuke's main series is “Universal Composition” which is a canvas filled with countless splashes, “Urge” which is work drawn dynamically with bare hands, and “Portrait of sapience” which is work drawn artifacts.
