Shakotan Peninsula: Brilliant Shakotan Blue Sea and Summer Sea Urchin Bowls

The Shakotan Peninsula, jutting out into the Sea of Japan from Otaru City and Yoichi Town in Hokkaido, is one of the prefecture's finest scenic spots, where the outstandingly clear cobalt-blue sea known as "Shakotan Blue" spreads out. The dynamic landscape woven from sheer cliffs and deep azure sea is known as one of the most beautiful coastlines in all of Hokkaido. In summer the seafood is also abundant, starting with sea urchin at its seasonal best, making this a popular area where you can enjoy both spectacular views and fine food.

The Spectacle of Shakotan Blue

Thanks to clear seawater with few impurities and the topography of the seabed, the sea around the Shakotan Peninsula shifts moment by moment from blue to green depending on the viewing angle and the weather. Cape Kamui in particular is a superb viewpoint, where from the "Charenka no Komichi" walking trail leading to the tip of the cape you can look out over the great expanse of Shakotan Blue spreading away on both sides. From the "Gate Forbidden to Women" to the tip of the cape is about 770 metres, roughly 20 minutes one way, but in strong winds or heavy rain the gate is closed and you cannot go beyond it. Walking the cape path with the wind on your face is as exhilarating as if you were moving across the sea itself, and on a fine day a blue so beautiful you feel you could be drawn into it spreads out before you.

Sea Urchin Bowls and Seafood

When it comes to the summer flavours of the Shakotan Peninsula, sea urchin is above all else. Bafun uni and murasaki uni are landed on the peninsula, and during the summer when the fishing season opens you can enjoy uni-don, rice bowls generously heaped with freshly caught sea urchin. With no off-taste and a rich sweetness that melts in the mouth, it is an exceptional delicacy that only the production area can offer. At the seaside restaurants, besides sea urchin you can also fully enjoy the rich bounty of the Sea of Japan such as squid and scallops.

Best Season and Access

The best season on the Shakotan Peninsula is summer, from June to August, when the sea shines at its most beautiful and the sea urchin fishery is in full swing. This is the ideal time to enjoy the Shakotan Blue sea and seasonal sea urchin at once. For access, it is convenient to use Yoichi Station on the JR Hakodate Main Line as a base and tour the peninsula's coastline by bus or car. Note, however, that Cape Kamui Nature Park has opening times and final admission times set for each season, and these also change with the weather. Check the opening status in the official information from Shakotan Town or the Shakotan Tourism Association before you set out. Head for the northern peninsula in search of the clear blue sea and its seafood.
