Shimamui Coast, Hokkaido – Cliffs Above Sapphire Seas
Located along the rugged Shakotan Peninsula of Hokkaido, Shimamui Coast is celebrated for its dramatic cliffs and astonishingly clear sapphire-blue waters. Recognized as one of Japan’s most beautiful coastlines, this northern gem offers sweeping ocean views framed by untouched natural scenery.
Far from crowded tourist hubs, Shimamui invites visitors into a landscape shaped by wind, sea, and time. The contrast between steep coastal rock formations and luminous waters creates a visual experience both powerful and serene.

The defining feature of Shimamui Coast is its elevated viewpoints. Visitors walk through a coastal tunnel that opens dramatically onto panoramic cliffside vistas overlooking the Sea of Japan.
From this vantage point, the horizon stretches endlessly, while the jagged coastline curves gracefully below—offering one of Hokkaido’s most photographed seascapes.
Sapphire Waters of Shakotan
The waters surrounding Shimamui are famous for their vivid blue tone, often called “Shakotan Blue.” This unique coloration comes from the region’s exceptional water clarity and reflective seabed.

Each season reshapes Shimamui’s visual character. Summer reveals the coast’s most vibrant blues, while autumn adds earthy tones to the surrounding cliffs.
