Genkai Quasi-National Park on the Itoshima coast delivers rugged shorelines, sea caves/cliffs, tidal scenery, and calm beach viewpoints with islands in the distance. Visit at sunrise/sunset for warm, low-angle light and vivid ocean color; weekdays in spring–autumn are less crowded. No special entry permits—go by train+bus or rent a car for easy access to multiple coastal spots and parking near trailheads/beaches.
