A magical stone that cures illness.
Sounds like a fairytail but such stone exists in Japan!
The name of the stone is "Hokutoseki"
The Hokutoseki can only be found in Taiwan and Tamagawa onsen in Akita prefecture, Japan.
Magazines introduce the stone as "Good for health", "Cures illness", so it became famous.
There is a scientific proof that the Hokutoseki is good for health. Unfortunately, you cannot take the stones home because they are protected by government.
Since you cannot take them home, people go to the Tamagawa onsen for their good health or wish to be cured whatever illness they may have.
They lie on the ground so they would feel the "power" of the stone.
Looks a bit strange doesn't it?
Don't worry, it is not a cult.
I don't know how good it is, but since it's good for health, I'd like to go there some day.
