Do you know Peat springs?
This means hot springs containing organic substance derived from plants, but it is not an official term.
However, if you trace the roots, surprisingly, you will reach the Napoleonic Wars.

When do you think hot springs are forced to close?
It is terribly sorry to see favorite hot springs shut down, but I have experienced such farewells several times.
More and more hot springs are facing difficulties in changing in times.
