Yunokawa Onsen is located in Hakodate City, Hokkaido, and is a hot spring resort conveniently located just 5 minutes from Hakodate Airport. It has long been known as one of Hokkaido's leading hot springs, and its location facing the Tsugaru Straits means that you can enjoy the hot springs while looking at the sea view, which is a major attraction. It boasts an abundant amount of water, mainly colorless and transparent chloride springs, and is said to be effective for neuralgia, muscle pain, poor circulation, and fatigue recovery. Each inn and hotel has a different open-air bath and large bath, and many facilities also offer day-trip bathing.

The spring quality is sodium-calcium chloride spring (neutral isotonic hot spring), and the spring temperature reaches 57 to 66 degrees Celsius. The colorless and transparent water contains a moderate amount of salt, and is characterized by its high heat retention effect and bactericidal effect that prevents the water from cooling down. It is effective for neuralgia, muscle pain, joint pain, poor circulation, and fatigue recovery, and is also useful for improving bruises, sprains, chronic skin diseases, and gynecological diseases. It is a famous hot spring that warms you to the core even in winter.

Yunokawa Onsen has a long history, and there are records of the Matsumae feudal lord visiting the hot springs for a cure. The hot spring town has a wide variety of accommodation options, from historic inns to modern hotels, so you can choose one that suits your travel style. Another attraction is the fresh seafood that is unique to Hakodate. There are many restaurants and inns where you can enjoy seasonal seafood caught in the Tsugaru Strait, such as squid, scallops, and crab, so you can enjoy both the hot springs and the seafood.

Yunokawa Onsen is also an ideal base for sightseeing in Hakodate. It is also easily accessible to major tourist spots such as the night view from Mt. Hakodate, Goryokaku Park, and Kanamori Red Brick Warehouse.
