Located in Kawanehon Town, Haibara District, Shizuoka Prefecture, Sumatakyo Onsen is a lush hot spring resort situated at the entrance to the Southern Alps. Many visitors combine their trip with visits to nearby highlights like the Yume no Tsuribashi (Bridge of Dreams) hanging over emerald green waters, the Oigawa Railway, and Oku Oikojo Station. It is recognized as one of the most popular secluded travel destinations in Shizuoka Prefecture. Sumatakyo can be reached by car or by transferring between the Oigawa Railway and local buses.
At Sumatakyo Onsen, Suikoen offers the serene and refined stay expected of an established traditional inn. Featuring retro modern interiors, cuisine showcasing local mountain produce, soothing hot spring waters, and a convenient location for visiting the Yume no Tsuribashi, it serves as an ideal base for exploring the Oku Oi region.
Suikoen is said to be the oldest inn in Sumatakyo, operating since the opening of the hot spring source itself. The interior is decorated with fine art and antiques, evoking a warm and nostalgic atmosphere. Beyond overnight stays, the inn welcomes guests for day trip baths and lunch.
The appeal of the property goes far beyond its history. Antique furniture echoing the Taisho Romance era, soft ambient lighting, and the deep stillness of a mountain retreat combine to offer an escape from daily life. It is an exceptional choice for international travelers seeking an authentic Japanese ryokan experience.
Dining
Dining at Suikoen centers on local mountain cuisine that reflects the natural surrounding area. Multicourse Japanese meals (kaiseki) highlight locally sourced ingredients, including wild mountain vegetables, mushrooms, and freshwater fish. For dinner, guests can enjoy a menu filled with the bounty of the mountains and rivers, such as salt grilled amago trout, local Kawane konjac, maitake mushrooms, seasonal mountain greens, and Shizuoka grown Koshihikari rice.
A standout specialty is the seasonal hot pot, made with ingredients nurtured by the rich nature of the Southern Alps. During the winter months, the inn often serves shishi nabe (wild boar hot pot), a signature dish of Sumatakyo that offers a taste of traditional mountain culture. Another unique offering is the shabu shabu featuring “Hamanako Sodati,” a premium Shizuoka pork brand, cooked in a broth infused with local green tea, a touch unique to Shizuoka’s tea growing heritage.
Guests can choose from several dinner menus to suit their preferences. For those who prefer a lighter meal, a small portion dinner plan is available.
Breakfast is served as a classic Japanese set meal. A popular highlight is the steamed fresh vegetables served in a bamboo basket, accompanied by side dishes that pair perfectly with freshly cooked rice. Both dinner and breakfast are served in four distinct dining spaces (Haikara tei, Bengara tei, Kuchinashi tei, and Akane tei), each offering a calm and relaxed setting.
Lunch is also available for non-overnight guests, featuring unique options like the “Wild Boar Oma Dam Curry” and seared venison. Pairing a day trip bath with lunch is a wonderful way to spend an afternoon.
Onsen
Sumatakyo Onsen is renowned for its velvety, skin soothing waters. At Suikoen, guests can relax in indoor and open air baths fed by natural hot springs flowing from the foot of the Southern Alps. The spring water is a simple sulfur type, characterized by its noticeably smooth texture. Because it leaves the skin feeling soft and refreshed after a soak, it is affectionately known as the “Water of Beauty Creation.”
The main indoor and open air baths rotate between men and women at 8:00 PM each evening, allowing guests staying overnight to experience both bath areas.
In addition to the public baths, Suikoen offers private family baths and accessible bathing facilities. The private family baths, fed directly by the hot spring source, can be reserved for 45 minute sessions, making them ideal for families, couples, or guests who prioritize privacy. The accessible bath allows wheelchair entry, ensuring guests with mobility concerns can enjoy the hot springs comfortably. Furthermore, the inn’s single special suite features a private, free flowing hot spring bath, allowing guests to soak at any hour of the day.
After bathing, chilled Kawane tea, a famous local product, is provided as a refreshing gesture of hospitality. Guests will also find green tea extract used in the shampoos, conditioners, and body soaps, offering subtle reminders of Shizuoka throughout their stay.
Day trip bathing is available for 600 yen per adult (towel included), with combined lunch and bath packages also available.
Rooms
The guest rooms at Suikoen offer a variety of options tailored to different travel needs. Traditional Japanese style rooms feature the warmth of tatami mats and views of the surrounding natural scenery of Sumatakyo. This option is ideal for travelers looking to enjoy a classic ryokan stay.
The Aizankan and Chikusuikan wings offer traditional Japanese rooms ranging from 10 to 14 tatami mats in size. Guests can relax surrounded by the fresh scent of rush grass while taking in views of the lush green mountains of Oku Oi.
The Momijikan wing features Taisho Romance style western twin rooms equipped with comfortable beds, including Simmons mattresses. This provides a stress free option for guests who prefer modern bedding or have difficulty sitting on tatami mats. Note that because Momijikan is located in a separate building, guests use a covered walkway when moving between areas.
For an elevated experience, the 85 square meter special suite (limited to one room) provides twice the space of a standard room. It features a 10 tatami Japanese room combined with two semidouble beds, along with its own private, free flowing hot spring bath for complete privacy.
All guest rooms are equipped with tea incense burners using local Kawane tea. The subtle tea aroma filling the room creates a calming atmosphere unique to a stay in Shizuoka.
Special Experience
One of the main highlights of staying at Suikoen is its convenient proximity to the Yume no Tsuribashi. As the symbol of Sumatakyo, this popular suspension bridge offers stunning views as it hangs over emerald green water. Because the walking path includes stairs and mountain trails, it is recommended to allow ample time and wear comfortable walking shoes.
By staying overnight, guests can set out early in the morning before day trip crowds arrive, enjoying a peaceful walk through the morning air. The crisp air, vibrant green mountains, sound of the river, and view of the suspension bridge combine to create a memorable experience.
Another draw is the opportunity to embrace the luxury of simply doing nothing. Removed from the busyness of daily life in Shizuoka’s quiet hinterland, guests can slow down, soak in the hot springs, savor local mountain cuisine, and relax in rooms filled with the scent of Kawane tea. Rather than rushing between sights, Suikoen offers a tranquil retreat centered on rest, nature, and well being.
