Tsushima (domain)

Tsushima domain was a historical region during Japan’s feudal era, located on Tsushima Island between Japan and Korea. It was controlled by a local ruler under the authority of the shogunate. The domain was strategically significant for trade, defense, and diplomacy, acting as a buffer zone and point of contact with Korea. Its economy was based on fishing, agriculture, and maritime activities. The domain's governance reflected the feudal system, with samurai serving the ruling lord. Today, Tsushima Island is part of Nagasaki Prefecture, but its historical domain played a key role in Japan’s regional relations and defense.
