An onsen is a place to revitalize your body and spirit.



- Three times a stay for Japanese -
Most Japanese bath at least three times during their stay when visiting Onsen resort.
Once between check-in and dinner, another after dinner,
and last before or after breakfast.
Of course there are people who bath even more.
This is to enjoy the different scenery in the morning, mid-day, and
at night out from open-air bath and to get the maximized efficacy to relax.

It also increases detoxifying effect and accelerates metabolism by soaking to
Onsen several times and perspiring tremendous amount.
Moreover, we Japanese simply love Onsen.
Hope you will also find amazing discoveries by lounging in Onsen
two or three times during your stay!
