Fujiya is a ryokan in Iwamuro Onsen that draws on its own spring. The baths are a cypress open-air bath and a large indoor bath with a view of the surrounding hills, plus a sauna. Lodging guests can also book a private family bath filled with the same water, and some rooms have their own cypress open-air bath. Day-use bathing (higaeri nyuyoku, 日帰り入浴) is possible only as part of a reserved meal plan, not as a bath-only visit.
