Bifuka Onsen (びふか温泉)

Introduction: The Northern Forest Sanctuary of White Birches and Sturgeon

Located in the heart of northern Hokkaido’s Nayoro Basin, Bifuka Onsen (びふか温泉) is a destination for those who seek the “Real North.” Bifuka is a town defined by extremes: it is home to some of Japan’s most beautiful white birch (Shirakaba) forests and holds the record for some of the coldest winter temperatures in the country. The onsen itself is located within the “Bifuka Island” park area, surrounded by the Teshio River. Unique among Japanese hot springs, Bifuka has successfully pioneered the farming of Sturgeon in its cold mineral waters, making it the “Caviar Capital” of Hokkaido. For international travelers looking to experience the silence of the northern wilderness, the taste of rare forest sap, and a thermal spring that warms you to the bone, Bifuka Onsen is an unforgettable detour on the journey toward Wakkanai.

Key Information Table

The Healing Waters: Thermal Warmth in the Coldest Land

Bifuka Onsen’s water is a Sodium-Chloride / Carbonate cold mineral spring. Because the natural source is cool, it is expertly heated to a perfect 42°C. The water is clear with a soft, slightly “thick” texture that feels incredibly soothing on dry skin—a common issue in Hokkaido’s frigid climate. The facility features a large indoor panoramic tub, a jet bath, and a sauna. In winter, the view through the large windows is like a living painting of white snow and dark birch trees. The high carbonate content helps to dilate peripheral blood vessels, significantly improving circulation. Locals often visit after a day of forest work or winter sports to “melt away” the deep cold of the North.

Top Recommended Stays & Bases

• Bifuka Onsen Hotel (The Main Lodge): A modern, comfortable hotel integrated with the bathhouse. It is famous for its “Sturgeon Course” dinners and its warm, wooden interior that reflects the town’s forest heritage.
• Bifuka Island Campground: One of the most popular campgrounds in Hokkaido. It is vast, featuring a lake for canoeing and direct walking access to the onsen. Ideal for “Van-life” travelers.
• Forest Park Log Cottages: Perfect for families or groups, these sturdy wooden cabins offer a private forest experience with the convenience of onsen access nearby.
• Bifuka Town Guesthouses: Several small guest houses near the JR station offer a more urban (yet still quiet) alternative for those traveling by train.

Must-Visit Scenic Spots: White Birches and Cold Records

Bifuka White Birch Forest: The largest collection of white birch trees in Japan. Walking through these ghostly white woods in winter or early spring is a surreal, cinematic experience.
Lake Bifuka: A peaceful lake located within the island park, perfect for canoeing in summer or watching the “Diamond Dust” ice crystals in winter.
Teshio River: One of Japan’s longest “wild” rivers. It is a prime spot for canoeists who want to embark on multi-day journeys through the Hokkaido wilderness.

Local Gastronomy: Caviar and Birch Sap

Bifuka offers flavors you cannot find anywhere else in Japan.
Sturgeon & Caviar: The onsen facility serves sturgeon sashimi (white, firm meat) and local caviar. It is a rare luxury at a reasonable price.
Birch Sap (Mori-no-Shizuku): In early spring, the town harvests sap from the white birch trees. It is a clear, slightly sweet water packed with minerals. You can drink it pure or find it in local sodas and sweets.
Vegetarian/Vegan Survival: Bifuka is a major producer of Pumpkin and Potatoes. The local roadside station (Michi-no-Eki) sells incredible pumpkin croquettes (check for dairy) and fresh corn. For vegans, the birch sap water is a must-try “forest energy drink.”

Cultural & Historical Context

Bifuka was historically a territory of the Ainu people, known as a rich hunting ground. In the early 20th century, it became a hub for forestry and the “Bifuka Forest Railway.” The town gained national fame when the author Haruki Murakami reportedly used the area as the inspiration for the setting of his novel “A Wild Sheep Chase.” The onsen was developed to provide a place of rest for foresters and has since evolved into a wellness hub that utilizes the town’s unique cold-water resources for sturgeon farming, blending traditional onsen culture with modern sustainable aquaculture.

Practical Travel Tips: Surviving the North

• Transportation: A car is highly recommended. The drive from Asahikawa via Route 40 is straightforward but long. In winter, be prepared for temperatures dropping below -30°C. Ensure your rental car uses “Cold District” Diesel/Fuel to prevent freezing.
• Tattoo Policy: Very relaxed. This is a family and camper-oriented facility. While modesty is always appreciated, international guests with tattoos are common and generally welcomed.
• Cashless: The main hotel accepts credit cards. However, the campground fees and the local “Sturgeon Museum” are cash-only (JPY).
• Connectivity: Surprisingly good. The Bifuka Island area has free public Wi-Fi provided by the town, making it a favorite for digital nomads.

2025-2026 Latest Updates

In 2025, Bifuka Onsen launched the “Birch Forest Glamping” experience, featuring high-end tents with wood-burning stoves. For the 2026 winter season, the town is introducing a “Coldest Temperature Experience Tour,” where guests can learn how to make ice sculptures and “boiling water fireworks” (throwing boiling water into -30°C air) before soaking in the hot onsen.

Safety & Manners

In the onsen, do not splash water and always sit on the provided stools. Bifuka is a “Bear Aware” zone—if you are walking in the birch forests, always carry a bear bell and stay on the trails. In winter, never leave your vehicle engine running in an enclosed space due to carbon monoxide risk from snow buildup. Respect the quiet of the forest; the silence is Bifuka’s greatest luxury.
