In winter, when it is below about -20°C (-4°F), the Tokachi river freezes. Due to the changes of temperature and tides, lumps of ice from the river break off and flow into the Pacific Ocean. The waves make them crash against each other and they become smoother forming smaller, rounded lumps of ice that get washed ashore.
