Discover Teshiogawa Onsen: A Hidden Sanctuary of Healing Waters in Hokkaido’s Smallest Village

Introduction: A Hidden Retreat in Northern Japan

Tucked away in Otoineppu Village, the smallest village in Hokkaido, Teshiogawa Onsen is a hot spring retreat unlike any other.
Established in 1989 as a local wellness facility, this onsen remains untouched by mass tourism—a true hidden treasure known only to those who seek serenity far from the mainstream.

Here, ancient geology, pristine nature, and warm local hospitality come together to create a truly exclusive and healing experience.

Origin: 150 Million Years in the Making

Teshiogawa Onsen draws its waters from Tokiwa Mineral Spring, which flows from the cross-section of a Cretaceous stratum—formed over 150 million years ago.
Once consumed as medicinal drinking water, this iron-rich, amber-hued onsen now offers both day-use and overnight stays.

Its waters are famed for their therapeutic properties, softening the skin and helping conditions such as burns, eczema, poor circulation, and even depression.
Rich in metaboric acid (HBO₂)—a rare component found in high concentration (1158 mg/kg per 2014 analysis)—it is recognized for its natural antiseptic and anti-inflammatory effects. That’s why it's often called “The Beauty Spring”.

Experience: Silence, Scenery, and Soothing Waters

From the open-air bath, guests can take in sweeping views of the Teshiogawa River, framed by forests that blaze with autumn color or glisten in the snowy stillness of winter.

Inside, 27 guest rooms—ranging from traditional Japanese-style to Western twin and deluxe hybrid suites—offer comfort and calm.
There is no elevator, so guests with mobility concerns are advised to inquire in advance.

The onsen also features a spacious wellness lounge for daytime relaxation, as well as a drinking spring corner where guests can sample the medicinal mineral water. Drinking the spring water is said to help with conditions like gastritis, ulcers, gout, and diabetes.

Cuisine: Authentic Flavors of the North

Dinner is served in the restaurant as a carefully crafted Japanese meal using locally sourced ingredients.
A true specialty is the Gensen Noodles—soba and ramen made using onsen water, available only here.

Whether you’re staying overnight or just stopping for lunch while touring northern Hokkaido, the restaurant welcomes all visitors. It’s a culinary hidden gem in its own right.

Conclusion: A Rare, Restorative Luxury

For seasoned travelers seeking something beyond luxury hotels and tourist routes, Teshiogawa Onsen offers the ultimate indulgence:
quietude, authenticity, and connection to ancient Earth.

With its healing waters, exclusive atmosphere, and untouched surroundings, this onsen stands as one of Japan’s last true hidden sanctuaries.
