In Okura village there is quite famous spa area called “Hijiori Onsen”, which has
more than 1200years history.
Now there are more than 20 Onsen hotels in the area, where many visitors enjoy
nice spa.
Among the hotels I’m happy to introduce you unique hotel offering you
“Cave Spa”.
As you see in the photo above, you should go through the real cave to reach to the bath.
You surely can get wonderful memory in this hotel “Matsuya Hotel”.
