Chugoku Junior College was established with its main administration building, music building, and ensemble building completed in 1983 in Niwa, Okayama City. These structures were designed by the renowned Urabe Architectural Office in collaboration with architect Keizo Matsumura. The campus represents an important example of 1980s institutional architecture in the Okayama region. The thoughtfully planned complex integrates three distinct functional buildings while maintaining architectural cohesion. These structures reflect the design philosophy and construction techniques characteristic of their era, making them significant works for understanding the development of educational facilities in contemporary Japan.
