Hotel Nagano International Hall is a distinctive hospitality structure completed in 1978, designed by the renowned architectural firm Amano and Yoshihara Design Office. Located in Nagano Prefecture's central district, this accommodation facility exemplifies the modernist design principles prevalent during Japan's high-growth era. The building's architectural language reflects careful consideration of functionality and aesthetic composition, making it a notable example of late 1970s Japanese hotel architecture. Situated at 576 Agatamachi in Nagano City, it continues to serve as an important landmark within the region's architectural landscape and hospitality sector.
