Overview
Nasu Onsen Sanraku brings you into one of Nasu’s most established hot spring ryokan stays. Founded in 1923, this long-running inn sits in Nasu Yumoto, close to the Imperial Villa area, with views across Nasu-no-gahara and the highland landscape. The ryokan’s history includes a visit by Emperor Showa when he was still Crown Prince, and the scenery around Sanraku remains closely tied to the story of the Nasu Imperial Villa.
You come here for a classic ryokan stay shaped by hot spring water, seasonal kaiseki dining, Japanese rooms, and quiet time in the mountains. Sanraku draws its own spring water from the Daima-no-sawa area and brings it directly to the baths without heating, circulation, or filtration, so the onsen experience stays central to your time here.
Accommodation
You can choose from rooms with private open-air onsen baths, rooms with private onsen baths, Japanese-style rooms, Japanese-Western rooms, and twin rooms with tatami. The room choices include the “Cattleya” Deluxe Suite with private open-air onsen, a Modern Suite with private open-air onsen, the “Kashiwa” Japanese Traditional Suite with private open-air onsen, the “Fuyou” Japanese Traditional Suite with private onsen, a Superior Twin Bedroom with Tatami, East standard Japanese-style rooms, West Wing Japanese-style rooms, and Twin Bedrooms with Tatami.
For a special stay, the “Cattleya” room gives you the largest room space at Sanraku, with a spacious living room, a bedroom with Simmons beds, and a private open-air bath filled with the ryokan’s own 100% source water. The bath water is drained, cleaned, and refilled each day, just like the large public baths.
The “Fuyou” room was renewed in June 2017 and gives you a 10-tatami Japanese room with a bedroom and a queen-size bed. You can also choose garden open-air bath rooms such as Kaede, Keyaki, and Nara, where you can enjoy source-flowing hot spring water and a footbath in the wide veranda area. The “Kashiwa” room faces the Japanese garden and includes a private open-air bath, a 10-tatami Japanese room, a veranda space, and a footbath where you can sit with tea or a drink after bathing.
The standard rooms also keep a strong Japanese ryokan feel. The West Wing view Japanese-Western rooms sit on the third and fourth floors and look toward Nasu-no-gahara. The East Wing sukiya-style upper Japanese rooms offer two connected Japanese rooms and views toward the Yamizo mountains and the changing natural scenery. West Wing standard Japanese rooms look toward the garden and, on clear days, toward Mt. Yamizo, while the bed-type standard rooms place two beds in a 10-tatami main room with a veranda by the window.
Your room includes practical items such as a hot water pot, air conditioning, LCD TV, refrigerator, safe, DVD player, humidifier, hair dryer, yukata, bath items, green tea, kelp tea, and Wi-Fi. You also receive a Japanese-pattern drawstring pouch that you can use when going to the baths, and Wi-Fi is available throughout the building.
Dining
Dining at Sanraku centers on seasonal kaiseki cuisine. Dinner changes with the month, the season, and the ingredients available at that time, and the ryokan changes its menu around 18 to 20 times a year. A kaiseki dinner may include 6 to 15 dishes, with each course designed to show the season through flavor, color, and presentation.
The kitchen uses carefully chosen ingredients from across Japan together with local Nasu produce. You may find house-made ponzu prepared with daidai citrus vinegar from Suo-Oshima in Yamaguchi, Tochigi rice grown in the fertile Kinugawa river system, and organic vegetables from contracted farms on the Nasu Highlands. Seasonal highlights include bamboo shoots in spring, pike conger in summer, matsutake mushrooms in autumn, and Kyoto vegetables in winter.
You dine in a setting matched to your room and plan. Sansui-tei offers five fully private Japanese-style dining rooms and is used for East Wing rooms and Japanese-style rooms with private open-air onsen. Shiki-tei serves the West Wing in a semi-private Japanese-style restaurant with table seating, tatami seating, and sunken horigotatsu-style seating. In-room dining may also be available for smaller parties, depending on your plan and room type.
Dinner starts at 6:00 PM, 6:30 PM, or 7:00 PM. Breakfast is a Japanese meal, with start times that change slightly by season. You can also request allergy support in advance, and you should share allergy details before arrival, as same-day changes may not be possible.
Onsen and Wellness
The hot spring is the heart of Sanraku. The ryokan draws water from its own source in Daima-no-sawa, near the Nasu Imperial Villa source area. The water travels around 5.4 kilometers down from the upper mountain area by natural flow, cooling on the way before it reaches the ryokan, without losing its spring quality.
You bathe in source-flowing water with no heating, no circulation, and no filtration. The spring produces around 800 liters per minute, and the water quality is listed as a simple hot spring, neutral, low-tonicity, and high-temperature. Traditional bathing benefits include relief for neuralgia, muscle pain, joint pain, frozen shoulder, bruises, sprains, sensitivity to cold, fatigue recovery, and general health support.
The large open-air bath places you under maple trees and seasonal branches, so your bathing experience changes with the time of year. Spring brings fresh green leaves, summer brings deeper green shade, autumn brings bright foliage, and winter brings a quiet view of resting trees. You can also enjoy the smaller open-air bath, and the two open-air baths rotate between men and women so you can experience both bath settings during your stay.
The large baths and open-air baths usually open from 3:00 PM to 1:00 AM and again from 5:00 AM to 10:00 AM. The men’s and women’s bath areas normally switch at 5:00 AM, giving you a different view in the morning. Day-use bathing is not available, so you enjoy the onsen as part of your overnight stay.
Guests with tattoos
If you have tattoos, the most comfortable choice is a room with a private open-air onsen or private onsen bath. These rooms let you soak in your own space with Sanraku’s source-flowing hot spring water. For shared public bath use, please confirm the current bathing rule when you book.
Facilities
Sanraku gives you spaces designed for slow ryokan time. The lounge looks out toward the Japanese garden and serves coffee, tea, and soft drinks throughout the day. From 4:00 PM to 6:00 PM, you can also enjoy a free drink service with options such as wine and sake.
The shop carries Sanraku original items and selected local products, including local sake, shiso nanban, and burdock rice crackers. You can also arrange Sanraku accommodation gift certificates, with options based on room type, plan, drinks, and other requests.
You have Wi-Fi in the lobby and rooms, free parking for up to 50 cars, and a shuttle bus service by advance reservation between Nasu-Shiobara Station and Sanraku. The shuttle usually departs Nasu-Shiobara Station at 2:40 PM and leaves Sanraku at 10:45 AM. All rooms are non-smoking, and the building provides a designated smoking room.
Activities
You can keep your stay simple with baths, meals, garden views, and quiet time inside the ryokan. Sanraku works well when you want to bathe several times a day, enjoy a long dinner, wake early for a morning soak, and let the mountain setting set your pace.
When you want to explore, Nasu gives you easy access to highland scenery, cafés, shops, and family-friendly attractions. Places introduced by the ryokan include Nasu Animal Kingdom, Nasu Ropeway, Minamigaoka Farm, Nasu International Country Club, Restaurant Cafe Penny Lane, Nasu Safari Park, Cheese Garden Gohokan, Nasu World Monkey Park, Okashi no Shiro, and Nasu Garden Outlet.
Additional features
Check-in is usually from 3:00 PM, and check-out is at 10:30 AM. You can pay with credit cards and debit cards, including Diners, Visa, Mastercard, JCB, and American Express, and QR code payments such as PayPay, Rakuten Pay, d払い, au Pay, and Merpay are also available.
You cannot stay in the ryokan room with pets, but a directly managed pet hotel called Villa du Wan sits on the grounds, and dogs staying there can use it free of charge when you stay at Sanraku. The building does not have barrier-free rooms, but wheelchair rental is available with advance request, and the team can try to arrange a room close to the elevator when possible.
Nasu Onsen Sanraku suits you when you want a ryokan with history, private source-flowing hot spring water, seasonal kaiseki meals, and a quiet highland setting. You come here to slow down, soak deeply, and experience Nasu through water, food, and mountain air.
