Kuyama

Kuyama [导山; くやま / Sunpaku: だずん] is a city located on Dainan in Zōhai Prefecture. As of 2020, it had an estimated population of roughly 16,000.
The oldest confirmed ruins on Dainan island were discovered in Kuyama in 1971, with artifacts including stone tools, rope, arrows, and pottery shards. It is thought by historians that the ancient residents of Kuyama, and possibly the rest of northern Dainan, were less advanced than the southern population and focused more heavily on a hunter-gatherer lifestyle rather than agriculture.
In terms of economy, Kuyama is mostly known for its beef and pork farming, along with its production of wool.
