Cape Shakotan, which juts out at the northernmost tip of Shakotan, is a popular area that has been selected as one of Japan's top 100 beaches and is the only underwater park in Hokkaido.
The coastline has steep cliffs carved by the rough waves of the Sea of Japan, and to the west is the view of Cape Kamui, which is very popular with tourists.
Even in the sea, there are strange rocks and columnar joints, making it a popular spot for divers who like topography.
It is also an exciting area for divers who like cameras and videos, as it is highly transparent and you can encounter a variety of creatures throughout the year.
From around June, schools of tens of thousands of Dall's porpoises and beaked whales of 12 to 3 meters can be seen off the coast of each point.
By the way, around April, killer whales migrate in groups.
