Saga Prefecture (佐賀県 Saga-ken) is a prefecture in the northwest part of the island of Kyushu, Japan. It touches both the Sea of Japan and the Ariake Sea. The western part of the prefecture is a region famous for producing ceramics and porcelain, particularly the towns of Karatsu, Imari, and Arita. The capital is the City of Saga. It is located on the northwest corner of the island, bordered by the Genkai Sea and the Tsushima Strait to the north and the Ariake Sea to the south. Saga's proximity to mainland Asia has made it an important gateway for the transmission of culture and trade throughout Japanese history. Largely rural outside of the two largest cities of Saga and Karatsu, agricultural and forested lands comprise over 68% of the total prefectural land area. There are six prefectural parks and one quasi-national park in Saga.
