I haven't been to Onsen for quite some time, and I missed soaking feeling so much.
My mum brought us to the good onsen spot.
The place is called 'Yu No Yama (湯ノ山)', well know for onsen healing.
Found by Koubou Daishi (弘法大師) in 1700's.
Behind the existing onsen facility, there is still a few hundred years ago's onsen facility.
This onsen is cold onsen and drinkable.
It was too good soaking till I soak too much.
I am still a Japanese, miss hot bath and soaking bath =P
