The Japanese feel that food tastes better, wood looks better, materials are better when natural. There is a belief that maximum enjoyment comes from the natural state.
This tradition on materiality was alive in Kurokawa’s work which treated iron as iron, aluminum as aluminum, and made the most of the inherent finish of concrete. The tradition of honesty of materiality is present in Kurokawa’s capsule building. In it, he showed technology with “no artificial colors." The capsule, escalator unit, elevator unit and pipe and ductwork were all exterior and exposed. Kurokawa opened structures and made no attempt to hide the connective elements, believing that beauty was inherent in each of the individual parts. This bold approach created a texture of elements that became the real materiality of the whole.
