The Nanatsugama Caves are designated as a National Natural Monument. It is a scenic spot formed by basalt rocks jutting out into the sea and eroded by the rough waves of the Genkai Sea over a long period of time.
The cliffs are deeply gouged, and there are seven caves lining the cliffs, as the name implies. The largest cave has a 3 m frontage and a depth of 110 m. Visitors can see columnar joints formed when lava cools and hardens, and the rock surfaces are regularly arranged like pillars.
Sightseeing cruises departing every hour from Yobuko Port will bring you closer to places to experience the menacing forces of nature. The cruise lasts about 40 minutes and is one of the must-do activities in Yobuko, with views of the Yobuko Ohashi Bridge and the Fukuoka and Nagasaki areas from the boat.
The top of Nanatsugama is a grassy field with an observation deck and boardwalk, ideal for a leisurely walk on a sunny day. At the northern end of the cape, there is a shrine dedicated to Empress Jingu, which is also worth visiting. The Nanatsugama area is also popular as a fishing spot.
