Japan is full of natural wonders that often leave visitors amazed, and among them is a hidden gem in Hokkaido. The Shirogane Blue Pond in Biei captivates travelers with its otherworldly color, a sight that feels both magical and surreal. For many, a trip here is not just about seeing a pond, but about experiencing the mysterious beauty created by nature and time.
It is said that the mesmerizing sapphire-blue color of this pond is the result of a volcanic eruption that occurred in 1988.
In Biei, Japan, lies a breathtaking pond with a striking turquoise hue. Known as the Shirogane Blue Pond, it was created after the 1988 eruption of Mount Tokachi. Much like the glowing geothermal pools in Yellowstone, swimming here is impossible because the water is highly toxic to humans.

Although swimming is prohibited, the pond has become a popular tourist destination. Its crystal-clear, blue waters combined with the eerie sight of bare, lifeless birch trees rising from the surface make it resemble a scene straight out of a fairytale.
Originally, the pond was dug to prevent volcanic mudflows from affecting the town. However, over time, water from the Shirahige Waterfall flowed down into Biei’s river system, interacting with volcanic deposits. Mount Tokachi, the source of Shirogane’s hot springs, absorbed a portion of this hot water, which then became underground springs. With traces of aluminum leaching from the waterfall’s rocky walls, the pond’s unique blue shade was formed through the mixture of underground springs, volcanic activity, and natural minerals. In addition, sulfur and limestone are also present in the pond, bleaching the rocks beneath its surface.

FAQ
1. What is Shirogane Blue Pond?
Shirogane Blue Pond is a man-made pond in Biei, Hokkaido, Japan, that has become world-famous for its otherworldly blue color. The striking hue is caused by natural minerals (especially aluminum hydroxide) in the water that reflect sunlight in a unique way, creating a glowing turquoise effect.
2. Why is the pond blue?
The water contains colloidal aluminum particles from nearby hot springs. These particles scatter sunlight in a way that emphasizes blue wavelengths—similar to why the sky appears blue. The result is a mysterious, almost magical, shade of blue that changes with the weather and seasons.
3. Where is Shirogane Blue Pond located?
It is located in Biei Town, Hokkaido, about a 20-minute drive from central Biei and 30 minutes from Asahikawa. Many visitors also pair a trip to the pond with the nearby Shirahige Waterfall and the flower fields of Biei and Furano.
4. What makes it unique?
- The surreal milky-blue water
- Bare, withered larch and birch trees rising from the pond, creating a dreamlike, almost painting-like scene

6. Is it natural or man-made?
The pond itself is man-made, formed in the late 1980s when a dam was built on the Biei River to prevent volcanic mudflow from nearby Mount Tokachi. However, the surreal blue phenomenon was a natural “accident” that turned the site into an unexpected wonder.
7. Can visitors walk around or get close to the water?
