Usuki (Pn) is a former castle town located on the east coast of Oita Prefecture in Kyushu. It is famous for its numerous stone Buddhas which are sculpted into the walls of cliffs and designated as national treasures. In Japan, Buddha statues are usually made of wood or metal, and stone Buddhas are rare.
Usuki's city center is situated about five kilometers from the stone Buddhas and maintains a charming old castle town atmosphere. The former samurai district here is characterized by its stone paved alleys lined by traditional buildings, with some former samurai residences open to tourists.
