Oita Prefecture is a prefecture of Japan on Kysh Island. The prefectural capital is the city of Oita. Around the 6th century Kyushu consisted of four regions: Tsukushi-no-kuni , Hi-no-kuni , Kumaso-no-kuni and Toyo no kuni. Present day Oita was part of Toyo-no-kuni, which means "Abundant Land". Toyo-no-kuni was later divided into two regions, upper and lower Toyo-no-kuni, called Bungo Province and Buzen Province. After the Meiji Restoration, districts from Bungo and Buzen provinces were combined to form ita Prefecture. These provinces were divided among many local daimyo and thus a large castle town never formed in ita. From this time that whole area became known as "Toyo-no-kuni", which means "Land of Abundance".
