Onga

Onga lies along the lower river of the same name in northern Chikuzen. In the Edo period, roads crossed the district on their way between the cities and ports of Kyushu, including the Karatsu road and routes leading toward the Nagasaki highway. The Onga River also carried boats downstream, conveying timber, farm produce and coal towards the ports of Ashiya and Wakamatsu. Road and river met in a landscape of low ground and waterways.
