“Hakone Kowakudani Onsen MIZUNOTO” is a Kyoritsu Resort inn quietly nestled in rich nature. With two hot spring sources to enjoy, seasonal Hakone cuisine, and guest rooms wrapped in pleasant tranquility, the inn offers a truly healing stay in Hakone.

Upon entering the inn, you are greeted by the cool tones of a suikinkutsu, a traditional Japanese water feature that creates koto-like sounds. Another charm is the pleasant sound of flowing water, which can be heard in the lobby, on the terrace, and in the open-air baths. Surrounded by gentle water sounds and greenery, your mind and body will naturally unwind.

Hakone, home to 17 hot spring areas, is famous as one of Japan’s leading onsen destinations. At “MIZUNOTO,” two of these springs—Kowakudani Onsen and Miyanoshita Onsen—naturally flow within the property.

In the new wing, Suihan no Sho, you can enjoy Kowakudani Onsen, while in the main building, Suigetsu no Sho, you can experience Miyanoshita Onsen. All staying guests may use both.
In addition, the garden features three private baths, each with its own unique atmosphere. Guests can enjoy a relaxing bath-hopping experience without ever leaving the inn.

“Suika no Sho” features two bathing areas—Sasa no Yu and Hana no Yu—each offering both an indoor bath and an open-air bath. From either open-air bath, you can view the lush garden, creating a spacious and relaxing atmosphere.

Sasa no Yu offers an impressive stone indoor bath and a fragrant hinoki cypress open-air bath. Hana no Yu features a warm wooden indoor bath and a rock open-air bath with a calm, soothing ambiance. There is also a reclining bath where you can relax and unwind.

Both Sasa no Yu and Hana no Yu operate on a gender-rotation schedule, allowing guests to enjoy both bathing areas during their stay.

“Suigetsu no Sho” features two bathing areas—Hoshi no Yu and Tsuki no Yu—each offering an indoor bath and an open-air bath. From the open-air baths, you can enjoy views of a beautiful bamboo grove.

The open-air bath at Hoshi no Yu is a natural rock bath, while the bright indoor bath with large windows is made of fragrant hinoki cypress. At Tsuki no Yu, both the indoor and open-air baths are crafted from smooth-textured hinoki, and there is also a sitting bath that gently warms your body from the feet up.

These baths also operate on a gender-rotation schedule, allowing guests to experience both Hoshi no Yu and Tsuki no Yu during their stay.

In the garden, there are three private open-air baths that draw water from Kowakudani Onsen: Hiragi no Yu, Kaede no Yu, and Wakatake no Yu. Each bath has its own unique atmosphere, allowing you to relax and soak while enjoying a different view of the garden.

No reservations are required, and staying guests can use the baths freely. Simply check the availability at the garden entrance; if a bath is vacant, you are welcome to enter. This makes them perfect for guests who want to enjoy a relaxed bath-hopping experience. Here, you can indulge in the luxury of having both the onsen and the scenery all to yourself.

For dinner, guests can choose between two courses: the Aburiyaki Kaiseki and the Ashigara Yuzen Kaiseki. (Some plans are excluded.)

The Aburiyaki Kaiseki features table-grilled dishes that let you enjoy each ingredient while it is freshly cooked and piping hot. With a personal grill at your table, you can cook the items to your preferred doneness and enjoy them together with the chef’s carefully prepared Wa no Zen set.

The Ashigara Yuzen Kaiseki offers a series of delicate dishes made with seasonal ingredients. The main dish is an individual hot pot prepared for each guest, with a choice of beef, pork, or duck.

Your dining venue depends on the course you select.
The Aburiyaki Kaiseki is served at Tsutsuji-tei, a dining venue with large windows overlooking lush greenery, where all seats are sunken kotatsu-style for a relaxed meal.
The Ashigara Yuzen Kaiseki is served at Ashigara, a dining venue with table seating. Enjoy the beautifully crafted kaiseki dishes in a calm atmosphere accompanied by the gentle sound of flowing water.

Breakfast features a luxurious Japanese set meal perfect for starting your travel day, with a main grilled fish and a variety of colorful small side dishes. The grilled fish can be reheated at your table, and as the aroma slowly rises, it’s sure to whet your appetite. Miso soup and white rice are available for free refills, so you can fuel up well before heading out for sightseeing.

Guest rooms are located in the new wing, Suika no Sho, and the main building, Suigetsu no Sho, each offering its own unique atmosphere. In every room, you can enjoy a sense of calm and feel close to Hakone’s natural surroundings without even stepping outside.
Another nice touch is the samue, a comfortable two-piece loungewear set provided in each room, allowing you to unwind and ease your travel fatigue in a relaxed environment.

“Suika no Sho” offers guest rooms with private open-air baths as well as rooms with semi-open-air baths.

The Japanese-Western style room with a private open-air bath combines the relaxation of traditional Japanese design with the comfort of Western-style furnishings. It also features a spacious open terrace, making it ideal for special occasions such as anniversaries or for anyone wanting a touch of luxury. Enjoy the exceptional experience of having Hakone’s seasonal scenery all to yourself, whether from your private bath or the terrace.

“Suigetsu no Sho,” Featuring Mainly Japanese-Western Style Rooms

Suigetsu no Sho offers a selection of Japanese-Western style rooms and Western-style rooms.

Connected to the lobby is the “Mizunoto Terrace,” a breathtaking spot with a front-row view of Hakone’s lush greenery. In the morning, when the sunlight shines in, the greenery looks especially vibrant and refreshing. You can also bring a cup of coffee from the lobby lounge out to the terrace and enjoy a luxurious moment surrounded by nature and the sound of flowing water.

Strolling through the garden, surrounded by lush greenery, is another relaxing way to spend your time at MIZUNOTO. A small stream flows gently through the garden, filling the space with a soothing sound. In the back of the garden, you’ll also find a small gazebo—perfect for taking a leisurely break.

The garden showcases beautiful scenery throughout the year: vibrant greenery in spring and summer, colorful autumn leaves in fall, and a serene snowy landscape in winter.
