To protect Japan's cultural heritage, the country's government selects through the Agency for Cultural Affairs important items and designates them as Cultural Properties under the Law for the Protection of Cultural Properties. Designated items are classified in a number of categories, one of which is Monuments (記念物 kinenbutsu). This category includes historic locations such as shell mounds, ancient tombs, sites of palaces, sites of forts or castles, monumental dwelling houses and other sites of high historical or scientific value; gardens, bridges, gorges, mountains, and other places of great scenic beauty; and natural features such as animals, plants, and geological or mineral formations of high scientific value.
