Historical/cultural features
The Japanese term “shinrin-yoku” (forest bathing) is now beginning to be used overseas. Just as bathing in a hot spring helps to soak your cares away, going for a walk in the woods is said to have a soothing effect. Tests by a variety of experts have shown Nukumidaira to perform exceedingly well as a soothing forest. As a result, it was certified as Japan's first Forest Therapy Base in 2006.
Forest therapy®: This is a private initiative run by the Forest Therapy Society, a specified nonprofit corporation. For further details, please visit the society's website.
Climate, flora and fauna
Located in the Sea of Japan climatic zone, this is one of Japan's foremost heavy snowfall areas and is blessed with abundant water resources. Its rich ecosystem includes a virgin forest principally made up of buna, Japanese beech (Fagus crenata Blume) and mizunara, one species of Japanese oak (Quercus crispula Blume), along with rare fauna such as tsukinowaguma, Asian black bear (Ursus thibetanus), inuwashi, Japanese golden eagle (Aquila chrysaetos japonica), and kumataka, mountain hawk-eagle (Nisaetus nipalensis). The white trunks of the beech trees and the snow that blankets the area in winter has led Nukumidaira to be nicknamed the “White Forest.”
Nukumidaira means “warm plain.” As the name suggests, the terrain in this Recreation Forest is quite flat, making it an ideal place for a walk. Even complete novices can enjoy forest trekking here, easily covering the 5.5 km of paths in the beech forest in around two hours, while getting a close-up view of the magnificent Iide Mountains and savoring the effects of forest therapy as it soothes both body and mind.
