Nikko, a mountain town northwest of Tokyo, is home to a cluster of traditional ryokan that blend hot spring bathing with spa-level amenities. These inns are not luxury resorts in the Western sense-they are Japanese-style hotels where the real draw is the on-site natural hot spring (onsen), often fed by mineral-rich volcanic waters. Visitors can expect tatami floors, yukata robes, and multi-course kaiseki dinners, with budgets typically starting around $100-$150 per person per night for a standard room, or $200-$300 for upgraded options with private baths and larger meals.
Top-rated properties include the Chuzenji Kanaya Hotel, a classical ryokan overlooking Lake Chuzenji with an indoor hot-spring bath, sauna, and a Western-style dining room serving seasonal dishes. For a more traditional experience, Honke Bankyu offers five hot-spring baths and a registered historical building that dates back to 1666. The Kinugawa Plaza Hotel, perched above the Kinugawa River, features natural hot-spring baths, a "Ganbanyoku" hot-rock spa, and an outdoor pool for summer. All three are non-smoking, family-friendly, and offer free parking. The best districts to stay are Chuzenji-ko for lakeside views and Kinugawa for access to riverfront baths and theme parks like Tobu World Square.
