Discover Cape Sukai, where the ocean's clarity defies belief. In the summer, the waters transform into a breathtaking emerald hue known as "Rebun Blue," creating a coastal paradise at the northern tip of Japan.

Located in the northern reaches of Rebun Island, Cape Sukai is one of the most beloved landmarks on the island, offering a panoramic view of a perfectly curved, picturesque inlet. As you stand at the observation point and look down, you are greeted by waters so exceptionally clear they take your breath away. On sunny summer days, the sea shifts its expression with every passing moment, glowing with an otherworldly clarity celebrated as "Rebun Blue" that instantly captures the heart of every traveler.

The transparency of the water is truly astonishing; even in the deeper sections, the rugged textures of the seabed remain vividly visible. While feeling the gentle sea breeze against your skin, a sense of profound serenity washes over you, as if even the sound of the waves is being softly absorbed by the landscape. For those trekking the "Cape Tour Course," encountering this view at the end of the journey is the ultimate reward for your travels. The brilliant harmony of the deep blue sky, the lush green cliffs, and the crystal-clear water creates a vivid panorama—a true masterpiece of natural art—one that makes the journey to this remote island more than worthwhile.
