The Swan House, officially known as Odate Municipal Sumonmae Residential Complex, stands as a distinctive residential project completed in 1994 in Odate, Akita Prefecture. Designed by architect Chiaki Nii's urban architectural practice, this apartment complex represents thoughtful contemporary residential design from the 1990s. Located at 122 Sumonmae, the building exemplifies the period's approach to communal housing with particular attention to its architectural character. The project demonstrates the designer's commitment to creating functional yet aesthetically considered living spaces for residents, making it a notable example of municipal housing architecture in regional Japan during that era.
