National Parks (国立公園 Kokuritsu Kōen) and Quasi-National Parks (国定公園 Kokutei Kōen) in Japan are places of scenic beauty designated for protection and sustainable usage by the Minister of the Environment under the Natural Parks Law () of 1957. National Parks are designated and in principle managed by the Ministry of the Environment. Quasi-National Parks, of a slightly lesser beauty, size, diversity, or state of preservation, are recommended for ministerial designation and managed by the Prefectures under the supervision of the Ministry.
Japan established its first kōen (公園) or public parks in 1873 (Asakusa Park, Asukayama Park, Fukagawa Park, Shiba Park, and Ueno Park). In 1911 local citizens petitioned that the shrines and forests of be placed under public protection and in 1929 the National Parks Association was formed. In 1931 the first National Parks Law () was passed and, after much study and survey, in March 1934 the first parks were established - Setonaikai, Unzen and Kirishima - with five more in December and a further four two years later. Three further parks were established under the old National Parks Law, in colonial Taiwan in 1937: the Tatun National Park, the smallest in Japan; Tsugitaka-Taroko National Park, the largest; and Niitaka-Arisan National Park, with the highest mountain in then Japan.Ise-Shima was the first to be created after the war, and a further seven had been added by 1955. In 1957 the Natural Parks Law replaced the earlier National Parks Law, allowing for three categories of park, the National, Quasi-National, and Prefectural Natural Parks. With minor amendments this established the framework that operates today.
