Tenkaiho Observatory

Tenkaiho Observatory (展海峰) offers one of the most breathtaking panoramic views of the Kujukushima Islands—an archipelago of over 200 lush islets often referred to as the “99 Islands.” Perched on a gentle hill, this scenic overlook provides a stunning contrast of deep blue sea and green islands stretching toward the horizon. It's a favorite among photographers, especially during sunset or cherry blossom season, when the landscape is bathed in golden light or framed by vibrant pink blooms, creating a truly magical atmosphere.

Easily accessible by car or local bus, Tenkaiho Observatory is a must-visit for nature lovers and anyone looking to escape the bustle of the city. The surrounding area includes flower gardens that bloom with seasonal color, peaceful walking trails, and a cozy café where you can enjoy the view with a drink. Whether you're capturing postcard-perfect shots or simply relaxing in the serene environment, Tenkaiho offers an unforgettable way to experience Sasebo's natural charm.
