Combining traditional Japanese elegance and modern comforts, Byaku Narai is the go-to luxury hotel in the historic post-town of Narai-juku in the Kiso Valley. Spanning four separate beautifully restored Edo-era heritage buildings, the 16 individually designed guest rooms are reminiscent of traditional Japanese dwellings, with many featuring private open-air Onsen baths. Guests enjoy access to serene gardens, a public bathhouse, a historic sake bar and an onsite gallery. To complete the experience, the inn's restaurant offers exceptional kaiseki dining, showcasing the finest seasonal ingredients and authentic local cuisine. Byaku Narai is a must-visit destination on the Nakasendo trail.
