Jinju Namgang Yudeung Festival in Jinju
An autumn lantern festival on Jinju's Namgang River marking a 1592 wartime tactic, when defenders floated lit lanterns to block night river crossings during the Imjin War. Thousands of lanterns now fill the river each year after dark, crossed by pontoon bridges and paired with daytime lantern-making workshops and riverside markets.
The Jinju Namgang Yudeung Festival traces its origin to a military tactic rather than a folk custom.
