Every winter, the coast near the mouth of the Tokachi River transforms into a glittering gallery of natural art known as Jewelry Ice. These ice formations are created when ice formed in the Tokachi River flows into the Pacific Ocean and washes ashore. As they are tumbled by the waves, their sharp edges are smoothed into rounded, gem-like shapes—clear and brilliant like real jewels. Unlike drift ice, this phenomenon is unique to this region and offers a once-in-a-lifetime view.

Jewelry Ice reflects light differently depending on the time of day, offering a stunning range of scenery: the ethereal glow of dawn, the soft light of morning, the dramatic rise of the sun, the contrast against Tokachi’s crisp blue skies, and the magical hues of an orange sunset. No matter when you visit, the ever-changing brilliance of these icy gems makes you want to return again and again.

Jewelry Ice typically appears between mid-January and late February along the sandy shores near the mouth of the Tokachi River at Otsu Coast. The phenomenon varies depending on weather conditions, so checking the local forecast before visiting is recommended.

Facilities like the Jewelry House, which offers rest areas and restrooms, make your stay more comfortable. Guided tours to see Jewelry Ice are also available, allowing you to enjoy this extraordinary natural wonder with ease. Don’t miss the chance to witness one of Hokkaido’s most photogenic winter spectacles.
