The University of Tokyo Engineering Building No. 6 Addition, completed in 1975, represents a significant work by the renowned architect Koh Yamamoto. Located in the heart of Tokyo's academic district in Bunkyo, this experimental and research facility exemplifies the modernist design principles characteristic of Yamamoto's practice. The structure demonstrates thoughtful integration with its university environment while maintaining architectural distinction. As a purpose-built academic facility from the mid-1970s, it reflects the period's commitment to advancing engineering education and research through carefully considered spatial design and functional clarity.
