Kunio Maekawa started by studying under Le Corbusier and Antonin Raymond and imposing on himself the mission of rooting genuine modern architecture in Japan. Japan and the Japanese architectural community should have the same technical foundations, economic substructures or social conditions of production as the developed regions of the time, and if that is not achieved in advance or in parallel, Japan Maekawa thought that modern architecture in Japan would be just a fake.

During and immediately after World War II, Maekawa set an example of a "technical approach" with works such as "Japan Mutual Bank Head Office", and was direct in overcoming the technical issues of modern architecture in Japan. Indirectly contributed. Even in the early and middle stages, the design works "the elaborateness of the volumes combined under the light" rather than the mere modern architecture (in the so-called international style) characterized by equal ramen structure , industrialization, functionalism, etc. It can be regarded as an accurate and magnificent game (Le Corbusier), and combines a human scale with folk or indigenous warmth. Since the mid-1960s, Maekawa has become extremely critical of the industrial society and some aspects of the rationalism that underpins it, but has not abandoned the best of the ideals of the modern movement to the end. Most importantly, it can be said that Maekawa worked throughout his life to establish the architect's profession and professional ethics.
