Saga (佐賀市 Saga-shi?) is the capital of Saga Prefecture, located on the island of Kyūshū, Japan. Saga was the capital of Saga Domain in the Edo period, and largest city of former Hizen Province. On October 1, 2005, the city expanded through merger with the neighboring towns of Morodomi, Yamato and Fuji (all from Saga District) and the village of Mitsuse from Kanzaki District to form the new city of Saga. With this creation, the city now neighbors the city of Fukuoka in Fukuoka Prefecture. On October 1, 2007 the towns of Higashiyoka, Kawasoe, and Kubota were also incorporated into Saga, further expanding its borders. Although Saga is the capital of Saga Prefecture, it can also be said to be within the Greater Fukuoka metropolitan area, and by extension, Fukuoka-Kitakyushu Metropolitan Area.
