Overview

You arrive at Hama no Yu in the heart of Kamisuwa Onsen, a short walk from both Lake Suwa and JR Kamisuwa Station. Set slightly back from the lively lakeside, this sukiya-style ryokan gives you a quieter base while keeping the waterfront, local shops, museums, and transport within easy reach.

Inside, you step into a two-storey Japanese-style lobby with a decorative floating stage and more than 100 colorful koi swimming through the surrounding waterway. Traditional stone lanterns, garden views, tatami rooms, seasonal kaiseki cuisine, and the hot springs of Kamisuwa bring the character of a classic ryokan stay together in one place.

From the upper floors, you can look across Lake Suwa toward the Northern Alps. Morning light, evening skies, and seasonal changes across the water give you a different view throughout your stay. Lower-floor rooms may have limited lake views, so you should choose an upper-floor category when the scenery forms an important part of your visit.

Accommodation

You can choose from 84 rooms, including top-floor Premium Suites with private hot spring baths, spacious special suites, Japanese-Western twin rooms, traditional tatami rooms, Western-style twin rooms, and single rooms.

For the most private experience, you can stay in one of four Premium Suites on the top floor. These spacious rooms measure either 90 or 105 square metres and include a private semi-open-air bath supplied with flowing hot spring water from the Nanatsugama source. Large windows place Lake Suwa, the surrounding mountains, and the changing sky directly in front of you as you soak.

Inside a Premium Suite, you sleep on two Simmons double beds and have a large living area for relaxing between meals and baths. Room features include a 65-inch television, an AirDog air purifier, a Cado humidifier, a Nespresso machine, a refrigerator, and a Balmuda electric kettle. The open layout gives you plenty of room to sit, read, enjoy a drink, or watch the sunset over the lake.

On the eleventh floor, the 105-square-metre Special Suites give you a wide view of Lake Suwa and the Northern Alps. Each suite combines a large Japanese tatami room, a separate bedroom with two semi-double beds, and a spacious living room. This layout works well when you want the atmosphere of a traditional Japanese room with the ease of sleeping in a bed.

The Japanese-Western Twin rooms sit on the tenth floor. The 45-square-metre Type A room includes twin Simmons beds, a 65-inch television, and an air purifier with a humidifying function. The larger 57-square-metre Type B room adds more living space and a desk where you can work or plan the next part of your journey. Both room types look toward Lake Suwa and the mountains.

For a more traditional stay, you can choose a Japanese-style room with tatami flooring and futon bedding. Standard rooms include a ten-tatami main room and a window-side seating area where you can sit with tea while watching the changing light over Lake Suwa. Larger corner rooms combine a 12.5-tatami main room with additional tatami spaces and a sunken kotatsu-style seating area.

Western-style twin rooms give you two semi-double beds and a simple layout suited to shorter stays or travelling as a pair. Single rooms include a semi-double bed and a desk, making them a practical choice when you travel alone or combine your onsen stay with work.

All rooms remain non-smoking, with a designated smoking space inside the building. Your room includes an empty refrigerator that you can use during your stay. Room amenities include shampoo, conditioner, body soap, a razor, and skincare products in most Japanese and Japanese-Western categories.

Dining

Your dinner brings you a monthly kaiseki menu shaped by the seasons of Shinshu and the wider Japanese calendar. Each course focuses on careful preparation, natural flavor, presentation, and tableware, allowing you to enjoy the meal with both your eyes and your palate.

Seasonal ingredients may include mountain vegetables, river fish, highland produce, mushrooms, Shinshu beef, and fresh seafood delivered from Toyosu Market. The exact menu changes each month so that you can taste ingredients when they are at their best. Depending on the season, your meal may include sashimi, grilled fish, simmered vegetables, a warming hot dish, rice, soup, pickles, and a carefully prepared dessert.

Rice comes from contracted growers in the Azumino area, where Koshihikari rice develops a soft texture and natural sweetness. You can also taste regional seasonings and Shinshu miso, helping each meal reflect the food culture of Nagano.

You can pair dinner with local sake, including Hama no Yu’s original ginjo sake, Ukishiro, which was created to complement Japanese cuisine. The Suwa area has a strong brewing culture, so a sake tasting can add another local element to your evening.

Breakfast follows a Japanese style and uses Azumino Koshihikari rice, Shinshu miso, and seasonal dishes. Rice, miso soup, grilled or simmered items, pickles, and small side dishes give you a warm start before a lakeside walk or morning bath.

Your dining place depends on your selected plan. You may eat in Ukishiro, a collection of private dining rooms facing a Japanese garden, or in Otomedaki, where private and semi-private rooms use comfortable table seating. Breakfast may also take place in a larger dining hall. Food allergies can be accommodated as far as possible when details are provided during booking.

Onsen and Wellness

You bathe in water from the Nanatsugama source, a blend of several Kamisuwa Onsen sources. The water is classified as a simple sulfur spring and is weakly alkaline, hypotonic, and naturally hot, with a source temperature of approximately 61.5°C.

Recognized bathing indications include fatigue, sensitivity to cold, muscle and joint discomfort, stiffness, bruises, sprains, and recovery after illness. A long soak can help you feel warm and rested after travelling, sightseeing, or walking around Lake Suwa.

The public bathing area includes separate spaces for men and women. In the women’s area, you can move between a black-granite bath, a hinoki cypress bubble bath, a rock-lined open-air bath called Kinsui, and a lavender bath. The large indoor bath and lavender bath remain available throughout the day apart from scheduled cleaning, while the open-air bath operates from early morning until midnight.

In the men’s area, you can enjoy a black-granite bath, a hinoki cypress bubble bath, the Hosen rock open-air bath, and a herbal bath. You also have access to a dry sauna and cold-water bath. The large indoor bath remains available throughout the day apart from cleaning, while the open-air bath and herbal bath operate from early morning until midnight.

The public baths, open-air baths, and private bath combine flowing hot spring water with circulation and filtration. Water may be added when needed to maintain a comfortable bathing temperature, and heat is used to prevent temperature loss during circulation. Low-odor chlorine treatment supports hygiene, and no artificial bath additives enter the hot spring baths.

For a quieter soak, you can reserve the private indoor bath Asa no Yu after checking in. This bath sits on the third floor and does not have an outdoor view, but you can bathe without sharing the space. Handrails and a shower chair support easier access, and the private setting works especially well when you travel with children or need additional privacy.

After bathing, you can enjoy complimentary karin water in the relaxation area. This refreshing drink combines extract from the quince-like fruit grown around Lake Suwa with water from the Kirigamine mountain system.

Guests with Tattoos

When you have tattoos, you can use the private indoor hot spring bath Asa no Yu instead of entering the shared bathing areas. You reserve this bath at reception after check-in, with bookings accepted for the same day.

You can also choose a top-floor Premium Suite with its own semi-open-air hot spring bath. This gives you unrestricted access to the Nanatsugama spring water inside your room and allows you to bathe whenever you wish without entering a communal space.

Facilities

At Lounge Kocho, you can relax in a spacious two-storey setting inspired by traditional Japanese design. A decorative floating stage, stone lanterns, garden details, and an indoor waterway filled with more than 100 colorful koi create an impressive welcome when you enter the ryokan.

The souvenir shop gives you the chance to take home flavors and crafts from Suwa and the wider Nagano region. You can browse local sake, Shinshu miso, soba noodles, wakasagi products, and seasonal specialties.

Private and semi-private dining rooms provide comfortable spaces for meals, while banquet rooms, conference rooms, and a convention hall can accommodate celebrations, meetings, and group stays. In the evening, you can enjoy the karaoke rooms or spend time in the karaoke lounge.

A relaxation area beside the baths gives you somewhere to cool down after your soak. Free Wi-Fi is available in the rooms and lobby, and a designated smoking space is provided inside the building.

You can also request useful items during your stay, including a wheelchair, humidifier, air purifier, trouser press, iron, or mobile phone charger. Traditional games such as Go, shogi, mahjong, and playing cards may also be available, subject to availability.

Activities

Lake Suwa gives you many ways to spend time outdoors. You can walk beside the water, cycle around the lake, or use an electric bicycle to reach Tateishi Park, Suwa Taisha, and other nearby sights. You can also join local SUP, kayak, Nordic walking, and yoga experiences around the lake.

The Suwa Lake Duck Tour takes you through the town before the amphibious bus drives directly into the lake. The complete trip lasts about 50 minutes and gives you both street-level and water-level views of the area.

You can try kayaking with an instructor, take a tandem paragliding flight from Fujimi Panorama Resort, create your own music box, or join a glass craft workshop. From October to March, covered boats on Lake Suwa allow you to try wakasagi fishing in greater comfort during the colder months.

For sightseeing, you can visit Suwa Taisha, the main shrine of the Suwa shrine network, or explore Art Nouveau and Art Deco glasswork at the Kitazawa Museum of Art. Katakurakan, known for its large marble public bath, sits close to the lake. Longer drives can take you along the Venus Line, up toward the panoramic views from Kurumayama, or as far as Matsumoto Castle.

Summer brings fireworks to Lake Suwa. The major Lake Suwa Fireworks Festival takes place in August, while smaller evening displays may run during the summer holiday period. Event dates and schedules can change each year.

Additional Features

You can reach Hama no Yu in about five minutes on foot from JR Kamisuwa Station. By car, the journey from Suwa Interchange takes approximately 15 minutes. Free on-site parking accommodates passenger cars and larger buses.

Children can stay at Hama no Yu, and the private bath gives you a comfortable option when you want to bathe together away from the public baths. Wheelchairs and simple beds can also be borrowed in limited numbers when arranged in advance.

Hama no Yu suits you when you want several room choices, full kaiseki dining, spacious public baths, private hot spring options, and easy access to both Lake Suwa and Kamisuwa Station. You can keep your stay simple with a traditional tatami room or make the lake view and private bathing experience the focus by choosing a top-floor Premium Suite.
