Underwater Observatory Ship New Shakotan
Hokkaido's rare marine park, underwater observation ship journey
A cruise ship touring Hokkaido's rare marine park, viewing the underwater world of Shakotan Blue from the glass-bottom underwater observation room.
Departing from Bikuni Port, you cruise around Gome Island, Biyano Cape, and Takarajima in about 40 minutes. As the ship advances, Shakotan Peninsula's unique coastline with many inlets and cliffs continues before you, overwhelming with its power. Descending to the underwater observation room in the ship's bottom, the endlessly transparent Shakotan Blue underwater world spreads across your view. You clearly see fish swimming in clear blue water and seaweed swaying attached to rocks, with light streaming into the water creating fantastical beauty. The scent of tide drifts, and you can feel the ocean's pulse with the ship's swaying.
On the return journey, seagulls chase and fly around the ship, their calls echoing. When feeding seagulls, you can see them skillfully catching food mid-air up close, drawing cheers from adults and children alike. Three attractions are condensed: varied underwater scenery, spectacular coastline of cliffs and inlets, and Shakotan Blue's transparency—a marine experience unique to Shakotan Peninsula awaits.
