Kujukushima

Kujukushima, meaning "ninety-nine islands," is a collection of 208 islands scattered across the waters between Sasebo and Hirado in northern Nagasaki Prefecture. Despite its name, the archipelago contains far more than ninety-nine islands, with the number simply representing "countless" in Japanese tradition. These islands are the exposed peaks of a submerged mountain range, formed through volcanic activity and subsequent changes in sea level over millions of years. The region was designated as part of Saikai National Park in 1955, protecting its unique coastal ecosystem and scenic beauty.

The islands hold historical significance as strategic points along ancient maritime trade routes connecting Japan with Korea and China. During the 16th century, Portuguese and Dutch traders frequented these waters, and the area played a role in Japan's early encounters with Western civilization. The sheltered bays provided safe harbor for vessels, and evidence of historical settlements can be found on several larger islands. The archipelago also appears in classical Japanese literature and artwork, celebrated for its misty morning vistas and intricate coastline.

Kujukushima offers visitors a distinctive maritime landscape characterized by forested islands rising from calm, turquoise waters. The Kujukushima Pearl Sea Resort serves as the main visitor hub, featuring an aquarium with displays of local marine life and observation facilities. Sightseeing cruises departing from the resort navigate through the islands, typically lasting 50 minutes to provide close-up views of the dramatic rock formations and secluded coves. The Tenkaiho Observatory, located at an elevation of 172 meters on the mainland, provides panoramic views across the entire archipelago and is particularly popular at sunset.

Several islands permit kayaking and boat excursions, allowing closer exploration of sea caves and narrow channels inaccessible to larger vessels. The clear waters support diverse marine ecosystems, making the area suitable for snorkeling during warmer months. Kashima Island, one of the few islands with regular ferry access, contains beaches and walking trails through subtropical vegetation.

Access to Kujukushima begins at Sasebo Station, reachable via the Seaside Liner train from Hakata Station in Fukuoka in approximately 1 hour 50 minutes. Local buses connect Sasebo Station to Kujukushima Pearl Sea Resort in roughly 25 minutes. The Tenkaiho Observatory requires a separate bus journey of about 30 minutes from central Sasebo. Admission to the Pearl Sea Resort aquarium costs ¥1,470 for adults, while cruise tickets are priced at ¥2,000 for the standard route. The observatory has free admission but charges ¥100 for parking.
