was a town located in Kishima District, Saga Prefecture, Japan.
On January 1, 2005, Ariake, along with the town of Fukudomi (also from Kishima District), was merged into the expanded town of Shiroishi.
The former Ariake Town Hall is now actually the site of the main Shiroishi Town Hall. Ariake borders the Ariake Sea, and from the Edo period through the Shōwa period land was reclaimed from this sea.
Ariake is long east to west. In the west it borders Shiota at Kishima Mountain, and in the east it borders the Ariake Sea and is an area of lowland rice paddies. To the north it becomes Shiroishi, and to the south it borders Kashima along the Shiota River. The eastern third of the town is reclaimed land. The town proper is northeast of the train station, Hizen-Ryūō, and near Megurie River.
The closest airport is Saga Airport.
