I recommend is the Arima Onsen.
Brown water is famous in one of the three major Koizumi Japan.
Guests can enjoy the town sow harmony with the elegant spa town in the mountains and nature.
Oita Beppu Onsen is recommended.
I have a lot of free hot looking, but there are a lot of good for Beppu Onsen hot spring town in
A free hot spots only the locals know about, because is a great place to commune with your locals since ancient times to Beppu ?
