Tsushima Island
Tsushima (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" (Kamino-shima) and "South Tsushima" (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 is in Nagasaki Prefecture.
The island group measures about seventy by fifteen km (43 by 9 mi) and had a population of about 28,000 as of 2022[update]. 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 lies on Tsushima and is divided into six boroughs.
Tsushima is located west of the Kanmon Strait at a latitude between Honshu and Kyushu of the Japanese mainland. The Korea Strait splits at the Tsushima Archipelago into two channels; the wider channel, closer to the mainland of Japan, is the Tsushima Strait. Ōfunakoshi-Seto and Manzeki-Seto, the two canals built in 1671 and 1900 respectively, connect the deep indentation of Asō Bay (浅茅湾) to the east side of the island. The archipelago comprises over 100 smaller islets in addition to the main island.
Tsushima is the closest Japanese territory to the Korean Peninsula, lying approximately 50 km from Busan. On a clear day, the hills and mountains of the Korean peninsula are visible from the higher elevations on the two northern mountains. The nearest Japanese port, Iki, situated on Iki Island within the Tsushima Basin, is also 50 km away. Tsushima and Iki Island are collectively within the borders of the Iki–Tsushima Quasi-National Park, designated as a nature preserve and protected from further development. Much of Tsushima (89%) is covered by natural vegetation and mountains. Tsushima has many mountains such as Mt. Ohira, Mt. Yatate, Mt. Hokogatake, Mt. Koyasan, Mt. Ontake, and Mt. Gogen.
The government of Japan administers Tsushima as a single entity despite the artificial waterways that have separated it into two islands. The northern area is known as Kamino-shima (上島), and the southern island as Shimono-shima (下島). Both sub-islands have a pair of mountains. Shimo-no-Shima has Mount Yatate (矢立山), standing 649 m (2,129 ft) high, and Ariake-yama (有明山), at 558 m (1,831 ft) high. Kami-no-shima has Mi-take (御嶽), 487 m (1,598 ft). The two main sections of the island are now joined by a combination bridge and causeway. The island has a total area of 696.26 km2 (268.83 sq mi).
Tsushima has a marine humid subtropical climate strongly influenced by monsoon winds. The average temperature is 15.8 °C (60.4 °F), and the average yearly precipitation is 2,132.6 mm. The highest temperature ever recorded on the island is 36.6 °C (97.9 °F), on 20 August 2013, and the lowest −6.8 °C (19.8 °F), in 1895. Throughout most of the year, Tsushima is 1–2 °C cooler than the city of Nagasaki. The island's rainfall is generally higher than that of the main islands of Japan; this is attributed to the difference in their size. Because Tsushima is small and isolated, it is exposed on all sides to moist marine air, which releases precipitation as it ascends the island's steep slopes. Continental monsoon winds carry loess, dust which is a highly fertile mix of clay and sand, from China in the spring and cools the island in the winter.
Tsushima's population is 28,502, with 49.3% male, and 50.7% female. 28,322 are Japanese people, and 150 are foreigners. 14.2% is in the 0-17 age group. 42.7% of its population is between the 18-64 age group. 38.6% is 65+ and older. Its population decreased by 1.9% from 2015 to 2022.
The island's fauna include leopard cat, Japanese marten, Siberian weasel, and rodents. Otters were discovered to be living on Tsushima in February 2017. Migrating birds that stop over on the island include hawks, harriers, eagles, and black-throated loons. Forests, covering 90% of the island, consist of broad-leafed evergreens, conifers, and deciduous trees including cypress. Honey bees are common, with many used to produce commercial honey. The Tsushima pitviper is a venomous snake endemic to the Tsushima. The islands have been recognised as an Important Bird Area (IBA) by BirdLife International because they support populations of Japanese wood pigeons and Pleske's grasshopper warblers.
