Yunokawa Onsen is a historic hot spring resort on the eastern side of Hakodate, renowned for its abundant hot spring water, convenient location, and beautiful seaside setting. Hakodate Airport is only about 5 minutes by car, or approximately 3 kilometers away, making Yunokawa one of Japan’s most conveniently located hot spring resorts near an airport.
The resort is also easily reached by Hakodate’s tram system, with the Yunokawa Onsen stop close to the heart of the hot spring district. Numerous ryokan inns and hotels line the coast, where guests can enjoy views across the Tsugaru Strait toward the Shimokita and Tsugaru Peninsulas. At night, the lights of fishing boats can sometimes be seen offshore.
Yunokawa Onsen has a long history dating back to the mid-17th century. The hot spring is traditionally said to have been discovered in 1653 when the son of the lord of the Matsumae Domain fell ill and a suitable place for recuperation was being sought.
Over the centuries, Yunokawa became known as a destination for toji, the traditional Japanese practice of traveling to hot springs for rest and recuperation. During the Hakodate War at the end of the Edo period, wounded soldiers of the former shogunate forces are said to have stayed here to recover.
As Hakodate developed into an international port in the late Edo and Meiji periods, the reputation of Yunokawa Onsen grew. The resort also became increasingly popular as a place for therapeutic bathing and relaxation.
The hot spring water at Yunokawa is classified as a sodium-calcium chloride spring. The water is clear and colorless, with a temperature of around 50°C at the source.
Chloride springs are traditionally appreciated for their warming qualities, and Yunokawa has long attracted visitors seeking relief from fatigue and relaxation. The spring is also traditionally associated with benefits for conditions such as neuralgia, muscle pain, joint pain, and sensitivity to cold.
One of Yunokawa Onsen’s greatest charms is its setting beside the sea. Hotels and traditional Japanese inns are clustered along the coast, allowing visitors to combine the pleasures of hot spring bathing with views of the Tsugaru Strait.
Some facilities also offer convenient footbaths and hand baths, providing an easy way to experience the hot spring water even without staying overnight. The relaxed atmosphere of the resort makes it an ideal place to slow down after exploring Hakodate.
A stay in Yunokawa is also an opportunity to enjoy the exceptional seafood of southern Hokkaido. The waters around the Tsugaru Strait are known for sea urchin, squid, horsehair crab, scallops, and other fresh seafood.
These local ingredients frequently appear in meals served at ryokan and hotels, allowing visitors to enjoy seasonal seafood alongside traditional Japanese cuisine. For food lovers, the combination of fresh local produce and a relaxing hot spring stay is one of Yunokawa’s major attractions.
Yunokawa Onsen offers a different atmosphere throughout the year. Spring brings cherry blossoms and fresh greenery, while summer offers lush landscapes and pleasant seaside scenery.
In autumn, colorful foliage adds warmth to the surrounding landscape. Winter transforms the resort into a snowy retreat, and bathing in an outdoor hot spring while looking out over a snow-covered landscape can be an especially memorable experience.
Yunokawa Onsen is not only a destination for hot spring relaxation but also a convenient base for exploring eastern Hakodate. Nearby attractions include Hakodate Tropical Botanical Garden, Hakodate Arena, and Hakodate Racecourse.
The combination of the tram network, buses, and its proximity to Hakodate Airport makes the area particularly easy to include in a short Hakodate itinerary. Visitors can enjoy the historic city center and then return to Yunokawa for a relaxing evening in a hot spring bath.
Various events take place in and around Yunokawa throughout the year. One of the best-known seasonal events is the Yunokawa Onsen Fireworks Festival, when fireworks illuminate the summer night sky above the hot spring district.
Local food festivals and cultural events are also held at different times of year, adding to the appeal of visiting Yunokawa beyond the traditional hot spring experience.
Yunokawa Onsen is counted among Hokkaido’s Three Great Hot Spring Resorts, together with Noboribetsu Onsen and Jozankei Onsen, and has also been selected as one of Japan’s notable hot springs in the 100 Famous Hot Springs selection.
Its long history as a place of recuperation, abundant chloride spring water, seaside location, and easy access have made it one of southern Hokkaido’s best-known hot spring destinations.
From its origins in the 17th century to its development as a modern resort, Yunokawa Onsen has remained closely connected with the history of Hakodate. Today, visitors can enjoy its clear mineral-rich waters, fresh seafood, seaside scenery, and the distinctive atmosphere of a traditional Japanese hot spring town.
For travelers exploring Hakodate, Yunokawa Onsen is an ideal place to combine sightseeing, local cuisine, and the deeply relaxing experience of a Japanese hot spring.
