The ANA Izusan Training Center, completed in 1981, stands as a notable example of modern institutional architecture in Atami, Shizuoka Prefecture. Designed by the Institute of Contemporary Architecture, this facility seamlessly integrates residential and educational functions within its structure. Perched in the scenic Izusan area, the building reflects the design philosophy of the early 1980s, combining practical functionality with architectural sophistication. The training center serves as both a lodging facility and social education institution, demonstrating thoughtful spatial planning that accommodates guests while facilitating professional development programs. Its location and design make it a significant case study in Japanese corporate architecture and hospitality design from this period.
