The Hsuirogadake Observatory is a stunning viewpoint located in Kosaza-cho, in the northwestern part of Sasebo City, Nagasaki Prefecture. Situated within the Saikai National Park, it offers a spectacular view of the Kujkushima (Ninety-Nine Islands) archipelago. From this vantage point, you can enjoy a sweeping panorama of the northern Kujukushima islands and even see the distant landscapes of Hirado. This area is renowned as a scenic spot where nature's many faces can be enjoyed throughout the seasons.
This area is part of the Saikai National Park, a region where the beautiful natural landscape has been carefully preserved for generations. The Kujukushima area itself is a highly dense archipelago consisting of 208 islands of various sizes. The unique topography creates a landscape of unparalleled beauty that is rare in the world. The natural environment surrounding Hsuirogadake serves as a precious natural resource for the local community and a significant piece of Japan's coastal heritage.

The greatest attraction is the panoramic view of the Kujukushima islands stretching out before you. The contrast between the various islands floating on the deep blue sea is truly mesmerizing. The scenery is particularly spectacular in the spring, when the surrounding hills are covered in blooming azaleas, adding vibrant splashes of color to the lush green landscape. Furthermore, the wide-open field of vision allows you to see all the way toward Hirado, providing a profound sense of openness and freedom.
The most recommended time to visit is around April. During this month, the azaleas reach their peak bloom, adding a beautiful layer of color to the scenery. The landscape changes significantly depending on the time of day; during the bright daylight hours, you can clearly see the shapes of the islands and the clarity of the blue sea, while the evening hours offer a more dramatic and romantic atmosphere.

The primary activity here is sightseeing and enjoying the natural beauty of the Kujukushima islands. It is an ideal stop during a scenic drive, allowing you to enjoy the view of the many islands through your car window or from the observation deck itself. It is a popular spot for travelers looking to refresh their minds in a natural environment and for photography enthusiasts seeking the perfect shot.
There are several other scenic viewpoints scattered around the Kujukushima area. For example, Nagakuruyama Park is a famous spot for viewing azaleas and also features campgrounds and open spaces. Other nearby locations like Ishitake Observatory and Yubariyama Observatory also offer breathtaking views from different angles of the Kujukushima archipelago. These locations are officially recognized as part of the 'Eight Views of Kujukushima.'
Access to the observatory is most convenient by car. As this is a natural area, please wear comfortable clothing suitable for light walking. Depending on the season, clothing suitable for a short stroll to see the flowers is recommended.
