Tsushima Island (Japanese: 対馬, Hepburn: Tsushima) is an island of the Japanese archipelago situated in-between the Tsushima Strait and Korea Strait, approximately halfway between Kyushu and the Korean Peninsula. The main island of Tsushima, once a single island, was divided into two in 1671 by the Ōfunakoshiseto canal and into three in 1900 by the Manzekiseto canal. These canals were driven through isthmuses in the center of the island, forming "North Tsushima Island" (Kamino-shima) and "South Tsushima Island" (Shimono-shima). Tsushima also incorporates over 100 smaller islands, many tiny. The name Tsushima generally refers to all the islands of the Tsushima archipelago collectively. Administratively, Tsushima Island is in Nagasaki Prefecture.
The island group measures about 70 km (43 mi) by 15 km (9 mi) and had a population of about 28,000 as of 2022. The main islands (that is, the "North" and "South" islands, and the thin island that connects them) are the largest coherent satellite island group of Nagasaki Prefecture and the eighth-largest in Japan. The city of Tsushima, Nagasaki lies on Tsushima Island and is divided into six boroughs.
In South Korea, this island is called Daemado (Korean: 대마도).
