In the years 1953-1958 he studied at the Musashino Academy of Fine Arts, Tokyo (graduated in 1958) in the studio of professors Saburo Aso and Choonan (Takeo) Yamaguchi.

Spacing, weight, texture and background surface are important to me in the same way - only the goal itself is opposite to the one that urban planning has. I do not mean to build something new, but to find and preserve things that we tend to forget, and the world from which we move farther away. I would like to find a form to draw them all into actual presence".These words spoken by the artist in 1967, describe most accurately the essence of his art, as in during all the years of his artistic work he constantly tries to implement them. In its conciseness and brevity, the characteristic form of Koji Kamoji's work recalls haiku poetry, where poets capture the feeling of transience.
