Keya Beach is a prominent coastal destination in Itoshima known for its expansive, shallow swimming waters that remain safe for families and beginners. The area is defined by the proximity of the scenic Keya no Oto, a large, basaltic cave formation located on the nearby headland. During the summer, the beach serves as a hub for marine activities and is equipped with seasonal seaside houses, or 'uminoie'. The shoreline offers expansive views of the Genkai Sea and is a popular spot for surfers during the off-season due to consistent wave patterns. Visitors can access the beach directly via a large coastal parking area adjacent to the sand. It functions as a seasonal bathing resort, with the majority of public amenities becoming operational only during the summer months.
