The Ota Ward Industrial Plaza, Tokyo Jonan Regional SME Promotion Center, and Metropolitan Public Housing complex represents a significant example of mixed-use urban development completed in 1996. Designed by Rui Sekkei, this multifunctional facility seamlessly integrates exhibition spaces, residential units, and office areas within a single architectural framework. Located in Minamisugamo, the building exemplifies the practical modernist approach to urban regeneration during Japan's 1990s development boom. The project demonstrates thoughtful spatial planning that accommodates diverse programs while maintaining architectural coherence, making it a noteworthy case study in Japanese contemporary architecture for its integration of public, commercial, and residential functions.
