What’s a Wind Cave?

A wind cave is created when a grotto or crevice allows wind to pass through a mountain.

While the wind is underground, the temperature and pressure are affected.

Air leaving the wind cave feels cooler and stronger than that entering the cave.

No matter how hot and sunny the day, the air coming from the cave tends to stay at

about 15℃. For this reason, when the cave was discovered in 1097 it was used

as a location to raise temperature-sensitive silkworms.

Nio is not the only place in Kagawa with a wind cave. There is another in Mt.

Takahachi that is used to study geology and agriculture.

The inside was cool and refreshing.

There’s more on Mt. Shio than just the wind cave, too.

There’s the Mountain Cherry Lookout where you can overlook lots of mountain cherry trees.

Come in the spring to see the blossoms!
