Nanohana Onsen Denden

Nanohana Onsen Denden draws two different springs and pipes both into each of its two indoor bathhouses: the large tub holds a clear salt spring, and the small tub a strong, concentrated salt water that turns amber from iron once it reaches the tub, with a sign asking bathers to keep their soak in it short. One bathhouse is a rock bath and the other a stone bath; the two swap between men's and women's use every day, and each has its own gas-fired far-infrared sauna, so both springs are there whichever side you get. The bathhouse sits at a roadside-station complex on the Shonai plain, in a building styled after an old shoya (庄屋) farmhouse among the rice fields. A tatami lounge and a handful of private rest rooms let day visitors linger after bathing, and a lunch-only restaurant serves set meals on site.
