Toyotomi Sarobetsu Frost Flowers

In the Sarobetsu Wetland of Toyotomi Town, during the depths of winter when temperatures drop below -20 degrees in windless conditions, ice crystals called 'frost flowers' bloom like flowers on the water surface. Delicate crystals formed on thin ice look just like a white flower field. This fleeting natural phenomenon disappears with the sunrise and can only be observed on early morning guided tours. If you encounter it, you'll treasure the sight for a lifetime—a miraculous spectacle.
