The purpose of this study is to clarify the gap in outlooks on Japanese architecture between Japan and The United States in 1950's, through an exhibition "The Architecture of Japan" in the Museum of Modern Art, New York. This study focuses on the museum's method of preparation for materials and publication of the exhibition. Through this study, it becomes clear: 1. There was a gap in views on Japanese architecture between those two countries. 2. MoMA aimed to introduce old Japanese architecture. 3. MoMA Tokyo intended to propose modern Japanese architecture.
