Introduction to the Rausu Sea: In winter from late January to mid-March, the Sea of ​​Okhotsk is frozen into a white land, and ice flows from Siberia to Hokkaido. The Sea of ​​Okhotsk is the only sea in Japan. The coast where mysterious drift ice can be seen is also the southernmost point in the world where drift ice has arrived. The sunset over the Rausha Sea is very beautiful.
