Sun Messe Nichinan is odd, photogenic, and very easy to remember: seven large Moai replicas lined up on a grassy slope above the Pacific. The replicas were made with permission from Easter Island, which gives the sight more weight than a random theme-park gimmick.
Come for the ocean view as much as the statues. It pairs well with Udo Jingu because both sit on the same dramatic stretch of coast.
