Overview
Yudagami Onsen Hotel Koyanagi brings you to a historic hot spring town at the foot of Mount Gomado in Niigata Prefecture. You stay in a place shaped by more than 280 years of bathing culture, where the saying “a good hot spring nearby is better than a famous one far away” still feels right.
From the upper floors, you can look out across the Echigo Plain as the view changes with the season. Green fields, evening lights, snow, and wide open sky all become part of the stay. Inside the hotel, the mood is warm and relaxed, with spaces for bathing, meals, music, manga, table tennis, and quiet time after the bath. You come here to slow down, eat well, soak deeply, and enjoy Niigata without rushing.
Accommodation
You can choose from 15 room types, all non-smoking. The rooms range from classic Japanese-style rooms to twin-bed rooms, barrier-free rooms, rooms with massage chairs, single rooms, and premium rooms with private hot spring open-air baths. This makes the hotel easy to match with different travel styles, whether you want a simple onsen stay, more space with family, or a private bath experience.
The standard main-building Japanese-style rooms give you a traditional ryokan feeling with tatami, futons, and a calm layout. If you want extra relaxation in your own room, you can choose a room with a massage chair and enjoy the view over Yudagami while you unwind.
Several rooms include beds for easier rest. Options include Japanese-Western rooms with twin beds and a 4.5-tatami Japanese space, twin-bed Japanese rooms with massage chairs, premium twin rooms with living areas, and barrier-free twin rooms with flat floors. The universal premium twin and the 32-square-meter Japanese-modern twin room offer easier movement from the entrance area into the room.
For a more special stay, the TAKUMI rooms bring hot spring bathing and Niigata craftsmanship into your private space. TAKUMI-PREMIUM opened in 2024 and offers a 100-square-meter layout with two twin rooms, Japanese-Western space, and a private hot spring open-air bath. TAKUMI-S opened in December 2023 and includes a private sauna, cold bath, analog records, Bluetooth speaker connection, 65-inch TV, Simmons semi-double beds, and a private hot spring open-air bath. TAKUMI-A and TAKUMI-B also include private hot spring open-air baths and design details inspired by Niigata craft traditions. The Kirikiri modern room with open-air bath was designed by interior designer Hidetoshi Iwakura and gives you a soft, refined Japanese room atmosphere.
If you travel alone, the single rooms were renewed in 2022 with darker natural and lighter natural color styles, Simmons mattresses, Wi-Fi, and Netflix viewing support. They work well for a quieter solo onsen stay or a workation.
Dining
Dining at Hotel Koyanagi focuses on seasonal Japanese cuisine that lets the ingredients speak clearly. The cooking is not showy for the sake of being showy. It values balance, timing, and the natural flavor of seafood, mountain ingredients, local vegetables, and Niigata produce.
Dinner plans include Niigata Umaimon Kaiseki, Bishoku Kyoen Kaiseki, spring seasonal courses, bamboo shoot courses, and TAKUMI room plans paired with premium meals. Niigata Umaimon Kaiseki brings together local food brands such as Niigata wagyu, Nanban shrimp, seasonal ingredients, and original desserts using fruits such as Le Lectier pear, Echigo-hime strawberries, and edamame. Bishoku Kyoen Kaiseki offers a richer meal with Niigata wagyu steak and shabu-shabu, nodoguro salt-grilled fish, and seasonal dishes prepared by the head chef.
The hotel also highlights ingredients from Tagami and Niigata. You can enjoy Niigata Koshihikari rice grown locally at Sato Farm in Tagami, spring bamboo shoots from the town’s bamboo groves, Koshinoume plums, Le Lectier pears, handmade sweets, and the hotel’s own hot spring sweets such as fresh caramel and cheesecake.
Meals are served in dining spaces such as Ajisai Kitchen Yugoya, a renewed dining venue created for the hotel’s 100th anniversary. The open kitchen lets you feel some of the movement and warmth of the cooking process, while table seating, partitioned areas, and private Japanese rooms make meals comfortable for couples, families, and groups. Breakfast is served buffet-style, giving you a gentle start with dishes prepared for a relaxed morning.
Onsen and Wellness
The hot spring is the heart of the stay. Hotel Koyanagi sits in Yudagami Onsen, a hot spring area that has been known for more than 280 years. The water is a sodium-chloride spring, and the hotel also has permission for drinking spring water, which is rare in Niigata.
The top-floor large baths look out over the Echigo Plain, giving you a wide view while you soak. The open-air bath has an infinity-style feeling, so the scenery feels close and open. The bath experience changes naturally through the day: fresh air in the morning, soft light in the evening, and town lights after dark.
Bathing hours are generous. The women’s bath is available from 4:00 AM to 10:00 AM and 11:00 AM to midnight, with cleaning from 10:00 AM to 11:00 AM. The men’s bath is available from 4:00 AM to midnight, with cleaning from 9:00 AM to 10:00 AM while bathing remains possible. The open-air bath is open from 4:00 AM to 10:00 PM for safety.
The sauna experience adds another reason to stay. The men’s sauna is a bona sauna with automatic löyly, set at around 80°C with a softer humidity than a dry sauna. The women’s sauna is a self-löyly sauna set at around 100°C, using hojicha tea poured over sauna stones so you can enjoy steam, aroma, and sound. The men’s cold bath is around 15°C to 16°C, while the women’s cold bath is around 17°C to 18°C. Sauna hours are from 6:00 AM to 9:00 PM.
For private bathing, you can reserve the observation source-fed private bath “Momoyu.” It was created to mark the hotel’s 100th anniversary and gives you an open view, fresh air, and a roomy bath that can be enjoyed with family or close companions. The bath is barrier-free, with a slope from the entrance, a flat layout, and a tub designed so you can sit before entering.
After bathing, you can rest in the after-bath lounge with cold water, manga, a drawing corner for children, and the drinking spring water area. You can also book body care at the massage corner on the sixth floor.
Guests with tattoos
If you have tattoos, you should note that the public baths and sauna do not allow tattooed bathers. Staff strictly enforces this rule. If you still wish to enjoy the hot spring water, you can reserve the private bath, which allows you to soak without restrictions. Advance booking helps secure your preferred time.
Facilities
Hotel Koyanagi has many spaces that make the stay feel easy and enjoyable. On the first floor, you can relax at Coffee & Music Lounge Ajisai, where you can enjoy music, Yukimuro Onsen coffee, and a gallery featuring works by local craftspeople. You can also try the Kiridama foot bath, made with paulownia balls from nearby Kamo City, a unique touch that gives the hotel a local character.
The recreation space adds a playful side to the stay, with a table tennis table made by Tendo Mokko that was used at the Rio Olympics, along with solid paulownia toys. The shop sells souvenirs and gifts connected to Yudagami Onsen and Niigata. On the second floor, Ajisai Kitchen Yugoya serves meals and can also be used for dining, drinks, and gatherings. The hotel also has Convention Hall Chitose, banquet spaces with chair-and-table seating, and a reservation-only karaoke room called Gomado.
On the sixth floor, you can use the massage corner, children’s drawing corner, manga corner, and lending items. Useful loan items include baby and family items such as waterproof bed mats and walkers. The hotel also offers Wi-Fi, accessible spaces, barrier-free rooms, ramps, rental wheelchairs, and parking.
Activities
You can enjoy your stay inside the hotel without needing to plan too much. Soak in the top-floor bath, reset in the sauna, cool down with water bathing, listen to records in the lounge, play table tennis, browse manga after your bath, enjoy craft beer, or spend quiet time in your room.
The area around Yudagami Onsen also gives you easy ways to explore. Mount Gomado’s hydrangea garden is about 5 minutes away on foot to the trail entrance and is known for around 30,000 hydrangeas during the early summer season. You can also walk the Yudagami Onsen healing road, visit Tōryūji Temple about 3 minutes away on foot, see the natural monument Tsunagi-gaya at Ryōgenji about 10 minutes away, or play golf at Yudagami Country Club about 5 minutes away by car.
Nearby places such as Chinjuso, Roadside Station Tagami, YOU・遊・ランド, local beaches, and Niigata sightseeing spots also make the hotel a useful base if you want to combine hot springs with short outings.
