Enter a world of wonder in the “Shakotan blue” seas of Hokkaido

Venture inside…to discover new worlds!

Blue Caves (Hokkaido)

In Japan, the words “blue caves” evoke images of the diving resort of Onna in Okinawa. But did you know Hokkaido’s Shakotan Peninsula has its own blue caves to rival those of Okinawa? The peninsula is home to a unique underwater landscape, surrounded by crystal-clear “Shakotan blue” waters and bathed in a complex interplay of shimmering light. Come visit this wondrous, deep blue world and enjoy all the marine activities it has to offer!

A full range of activities in the pristine blue seas

There are plenty of things to do in the Blue Caves both above and below the water. A boat cruise is a safe and easy way for everyone to enjoy the caves. For the more adventurous, there are clear-bottomed kayaks offering an unobstructed view of the sea floor below. And those who want the full undersea experience can try snorkeling and diving. Whether you’re looking for relaxation or excitement, with so many marine leisure activities to choose from, there’s truly something for everyone.

A ceiling of light shining down on the deep blue

Without a doubt, the greatest charm of the Blue Caves lies in exploring their deep blue undersea world. As you swim through the crystal-clear waters, look up and you’ll see shafts of sunlight piercing through gaps in the rocks above, like natural skylights. If you’re lucky, you may even be greeted by a school of fish, their scales flashing silver in the light from above. And poke your head out of the water, and you’ll hear the soothing sound of the waves lapping against the walls of the caves.

Fresh sea urchin rice bowls, a Shakotan delicacy

Nothing says summer in Hokkaido like a rice bowl piled high with fresh sea urchin meat. The sea urchins in Shakotan are especially sweet and tasty.

Magnificent views from Cape Kamui

Cape Kamui, a narrow promontory jutting out into the sea near Shakotan, offers breathtaking views of sheer cliffs and clear, blue waters. A walk along the high ridge to the tip of the cape is an experience not to be missed.
