Stayed this onsen ryokan in Yufuin in 2013. We have booked 5 rooms but to our surprise when we arrived we were led to 5 separate houses, each with a living room, one or more bedrooms on upper floor, bath and in-room onsen !! This ryokan has a huge premise – the big rotenburo is uphill with stairs with its own well. Mt Yufu could be seen from there. Unlike elsewhere in Yufuin where onsen is transparent, in this small area of Yufuin onsen is bluish in colour.
