Ice bubble in Hokkaido, Lake Nukabira. It is a rare phenomenon in which air bubbles are trapped in a frozen lake. This time, it was extremely cold below -20°C because it was shooting at dawn, but when I found it, the cold was blown away! The Taushubetsu River Bridge is also famous in the Lake Nukabira, but this is also deteriorating and it is not known how long you will be able to see the current 11 arches, so it is a recommended spot right now!
