Kita Onsen（株）北温泉旅館

Kita Onsen has been a working ryokan since at least the Edo period, and the building barely seems to have changed: rough wooden floors, low ceilings, a Tengu mask watching over the entrance. The spring itself has reportedly been known for over 1,200 years. There are five distinct baths: a riverside rotenburo, a large outdoor pool (the kind with a small slide, which gives a sense of the relaxed spirit of the place), and several indoor ones including the women's bath upstairs with its window wall looking out onto greenery. Most of the outdoor baths are mixed (konyoku) or open to men and women at different times. It became briefly famous abroad as a filming location for the film Thermae Romae.
