Saikai National Park

Established in 1955, Saikai National Park covers a coastal area of northwestern Kyushu, spanning parts of Nagasaki, Saga, and Kumamoto prefectures. The park is characterized by a rugged coastline dotted with over 400 islands, notably the Kujūku Islands (meaning "ninety-nine islands"), though there are many more small islets scattered in the East China Sea. These islands feature dramatic cliffs, small sandy beaches, and lush vegetation, providing important habitats for diverse marine and terrestrial species. The park’s ocean waters support a variety of fish and bird species, especially migratory seabirds, making it a significant location for wildlife enthusiasts and birdwatchers.

Historically, the park area has been shaped by maritime culture and fishing communities, with several historic fishing villages and lighthouses accessible to visitors. Saikai’s townscapes are enhanced by scenic routes and quaint ports where fresh seafood is a highlight. Popular activities include hiking along coastal trails, island hopping by boat, kayaking through calm waters, and exploring the natural marine environments through snorkeling and diving. Visitors are often drawn to the panoramic views from observatories such as Nunei Observatory, and to remote islands like Nomijima, which offer tranquil beaches and walking paths.

The park’s combination of coastal landscapes, island biodiversity, and cultural sites create an engaging experience for both day visitors and those seeking longer outdoor adventures. The mild climate allows year-round access, though spring and autumn are especially favored for hiking and sightseeing. Saikai National Park is managed with a focus on balancing public access with the protection of fragile coastal ecosystems, allowing visitors to appreciate the scenic beauty and natural heritage of this remote maritime region.
