A traditional onsen (hot springs) resort that dates back to the 1870's, Arai Ryokan has a serene, old-world feel, evoked by the traditional Japenese wooden-beam architecture, covered walkways and bridges, and wooded surroundings. The spa has pools and tubs fed by the natural hot springs, including the main communal bath (which was built in 1934 and is registered as a National Historic treasure) and several other mixed group, family, and private baths. Bathe outdoors in the Komorebi pool or in the modern spa pool. There's also a tea lounge and award-winning restaurant serving kaiseki meals.
While in Shujenzi, be sure to visit Shujenzi Temple, built in the year 807.
