About
New Heartpia is a hotel of 24 rooms, mostly Japanese-style, built around its own onsen well drilled on the grounds. The water is plainly salty and smooth on the skin, filling a rotenburo lined with rokuho stone (六方石) open to the sky and a big indoor bath with a regular sauna, a mist sauna, and a cold plunge. Day-use bathing is available, and the rest area afterward has reclining seats, games, and a manga corner for lingering. Reserved private baths are kept for overnight guests only.
