The building with timber latticed facade reflected in the water is a symbolic representation of Fuji as a “mountain of water”. Inside, the building shaped like an inverted mountain is a curving spiral ramp which leads gradually from the first floor up to the fifth. Viewing the exhibits as they ascend the slope, visitors can enjoy a virtual experience of climbing the mountain. When reaching the top (fifth) floor, there is an observation hall with a large picture window offering a breathtaking panoramic view of the real Mt. Fuji, which changes its expression from moment to moment. Spring water from Mt. Fuji is drawn into the Centre and used as an air conditioning heat source, and then channeled to the Reflecting Pool in front of the building, architecturally conveying the cycle of water on Mt. Fuji.
