Overview

Fourtreat Plus Nasukogen, formerly Nasukogen Hotel View Palace, is a highland hot spring hotel in Nasu, Tochigi. You stay in a quiet adult-focused retreat surrounded by Nasu’s mountain air, greenery, open views, and the famous milky water of Shika-no-Yu. The stay is designed around four simple pleasures: rest, recreation, relaxation, and retreat.

This is a good choice when you want a relaxed Nasu stay with natural sulfur open-air bathing, spacious rooms, lounge time, local food, and easy access to sightseeing spots such as Nasu Ropeway, Nasu Highland Park, Nasu Rindou Lake View, Hachiman Azalea Grove, and Nasu Stained Glass Museum.

Accommodation

You can choose from four main room types: Deluxe Twin Room, Standard Twin Room, Natural Light Room Japanese-Western Style, and Natural Light Room Twin. All rooms are non-smoking. The rooms are spacious for a highland hotel, with soft natural light and views that change with the season and time of day.

The Deluxe Twin Room gives you 42㎡ of space, two semi-double beds, a Ryukyu tatami living area, unit bath, and warm-water washing toilet. It works well when you want a more open room with a calm Japanese touch.

The Standard Twin Room is 32㎡ and has two semi-double beds, a unit bath, and warm-water washing toilet. It gives you a simple, comfortable base for Nasu sightseeing and onsen time.

The Natural Light Room Japanese-Western Style is 45㎡ and combines two semi-double beds with three Japanese futons. This room is a good fit when you travel with family or friends and want both bed sleeping and a Japanese-style floor area.

The Natural Light Room Twin is 32㎡ and has two semi-double beds. Wood tones and natural light give the room a softer feel, making it a good choice for a quiet couple’s stay or a simple Nasu retreat.

Room items include TV, internet connection, kettle, tea set, refrigerator, hair dryer, warm-water washing toilet, body soap, shampoo, conditioner, toothbrush set, brush, towels, bath towels, yukata, slippers, and safe. Desk lamps and humidifiers are available as loan items.

Dining

Dinner is served as course-style dining. From January 19, 2026, dinner service changes from half-buffet style to course meals, giving you a slower dining experience with dishes served one by one.

Dinner courses use local ingredients and French-inspired creative cooking with Japanese accents. Course examples include colorful vegetable bagna càuda, sea bream carpaccio with strawberry sauce, green pea potage, kinmedai poêlé with Parmigiano cheese, Tochigi wagyu sirloin grill with mustard miso sauce, seasonal dessert, and herbal tea. Other courses may feature amadai, Spanish mackerel, domestic beef sirloin, or Tochigi Yashio pork, depending on your plan and ingredient supply.

Breakfast is served buffet style with local Tochigi ingredients. You can enjoy dishes made with Nasu Goyou eggs, grilled fish, tofu, rice, curry, miso soup, bread, salad, fruit, sweets, and drinks.

Onsen and Wellness

The open-air baths use natural sulfur hot spring water from Shika-no-Yu, one of Tochigi’s oldest hot springs. The water is milky white, slightly thick, and acidic. You can soak outdoors while breathing the highland air and enjoying the changing sky above Nasu.

The spring quality is simple acidic sulfur hot spring water, hydrogen sulfide type. The pH is 2.36, and the source temperature is 53.7°C. Listed indications include chronic muscle and joint pain, lower back pain, neuralgia, frozen shoulder, bruises, sprains, cold sensitivity, poor peripheral circulation, mild hypertension, diabetes, mild high cholesterol, hemorrhoids, autonomic instability, stress-related symptoms, recovery after illness, fatigue recovery, and general health promotion.

The open-air bath uses flowing hot spring water with added water and heating. The indoor large bath is not hot spring water, so the open-air bath is the main onsen highlight. Bath hours are usually early morning, then midday to midnight, though afternoon opening may shift on cleaning days.

You can also enjoy the women-only Steam Spa, a warm steam therapy that helps the body heat from within. It is available by reservation at check-in.

Guests with Tattoos

The property does allow bath-time cover wear designed for covering surgery scars in the large public bath which can extend to tattoos too. You need to bring your own approved cover wear if this applies to you. If your tattoos are visible, bathing in the public onsen is not possible.

Facilities

Fourtreat Plus Nasukogen gives you a calm highland stay with a lounge, restaurant, natural sulfur open-air baths, large indoor baths, Steam Spa, and outdoor parking. The lounge looks out toward the Kanto Plain and offers a relaxed space for drinks, finger food, reading, and workation-style time. The library area has more than 200 books, and desks with power outlets make it easy to read, plan your day, or catch up on work. Wine and finger food are served during the afternoon lounge service.

The restaurant has large windows and a spacious setting where you can enjoy Western-style course meals with Japanese care and local ingredients. The public bath area includes the natural sulfur open-air bath from Shika-no-Yu and a large indoor bath that uses heated water rather than hot spring water.

You also have Wi-Fi, a front desk, parking, room amenities, vending machine access through travel listings, and selected loan items such as desk lamps and humidifiers. The building has 42 rooms in total, and parking is available outdoors without advance reservation.

Activities

You can use the hotel as a quiet base for Nasu sightseeing. Nasu Rindou Lake View and Nasu Highland Park are each about 15 minutes away by car, giving you easy options for family-friendly outings, rides, lakeside time, and farm-style activities.

For mountain scenery, Nasu Ropeway is about 15 minutes away by car and takes you toward the upper area of Mt. Chausu. Komadome Waterfall is also about 15 minutes away by car, while Hachiman Azalea Grove is about 10 minutes away and is known for spring azaleas across a large highland area.

You can also visit Nasu Flower World, Nasu Garden Outlet, Nasu Ashino Stone Plaza Museum, or Nasu Stained Glass Museum. These spots make it easy to shape your stay around nature, shopping, art, and slow highland drives.
