The wind caves are a mysterious spot where near-freezing winds blow even during summer due to gaps in the mountain through which air is cooled as it passes.

The cool air of the wind caves, which are located at a low elevation, support communities of alpine plants that normally grow at altitudes of 1,000 meters or higher. This rare phenomenon has been designated as a natural monument of Japan.

From the Meiji (1868–1912) through the Taisho (1912–1926) periods, this cool air was used to store foods like a refrigerator.

The Nagabashiri Wind Caves can be said to be Japan’s top wind cave attraction due to its large scale and ease of access from the highway, as wind caves are often located deep within the mountains.

Not only can you experience the cool air, you can also learn more about the wind caves at the adjacent Nagabashiri Wind Caves Eco-Museum, which offers information in six different languages.
