Traditional elements of Japan such as origami and modern aspects of art were harmonised, featuring a ridgeline like the famous Japanese mountains Mt. Yatsugatake and Asama-yama outlining the site. The new type of architecture was designed in response to the environment.
The construction imitates a sharp ridgeline and consists of geometrical forms like origami. It is realised in a form whereby curves and straight lines face nature, contrasted with the art museum that reflects the personality of the designer, who is a Japanese-style painter.
Light is reflected onto the wall and roof made of titanium alloyed zinc, at various angles to the ground, while the glass of the façade reflects the surrounding green and the mountain range.
