FOREST is a commercial facility located in Karuizawa, Nagano Prefecture, completed in 1987. Designed by the Kunihiko Hayakawa Architectural Laboratory, this building exemplifies the architectural approach of its era. Situated in the scenic mountain town of Karuizawa, FOREST was conceived to serve the commercial needs of the community while harmonizing with the natural landscape. The structure reflects thoughtful design principles that balance functionality with environmental sensitivity, making it a noteworthy example of late twentieth-century commercial architecture in Japan's premier resort destination.
