An Imperial decree in July 1899 established Izuhara, Sasuna, and Shishimi as open ports for trading with the United States and the United Kingdom.^[2]

On April 1, 1975, Toyotama Village was promoted to the status of a town. Mine Village was also elevated to the status of a town in the following year.

The modern city of Tsushima was established on March 1, 2004, from the merger of six towns on Tsushima Island: Izuhara, Mitsushima, and Toyotama (all from Shimoagata District), and Mine, Kamiagata, and Kamitsushima (all from Kamiagata District). Both districts were dissolved as a result of this merger.

The city of Tsushima is located on Tsushima Island and other small neighbouring islands, lying slightly to the west side of Tsushima Strait, south of the Sea of Japan and north-east of the East China Sea. The island also lies between the Korean Peninsula and the Japanese mainland. Its coastline has a total length of 915 km. Asō Bay, a prominent bay with a rias coastline, is located between the islands. Tsushima lies about 60 km from Iki, 138 km from the city of Fukuoka, and 49.5 km from Busan, South Korea.

The population of Tsushima Island has been decreasing significantly. Between the years of 1995 and 2000, the decline was 5.2%.^[11] As nuclear families replace the traditional extended families, the average household is smaller, as is the total population.^[11] The elderly comprise nearly a quarter of the population here, compared to 20.8% of the Nagasaki Prefecture as a whole, and 17.3% of the population of Japan.^[11]

Religious traditions on Tsushima Island mirror those of the rest of Japan, with a majority of the population adhering to Buddhism or Shinto.

Many Tsushima residents are employed as fishermen. It is also known for its pearl culture.^[12] The natural environment of the Tsushima Islands also contributes to the local tourism industry.^[13] Beaches are crowded with tourists in the summer.^{[citation needed]}

Tsushima has received 12 digital TV channels from Fukuoka and mainland Nagasaki prefectures : NHK-G 11, NHK-E 21, NBC 31 (JNN), NIB 41 (NNN / NNS), NCC 51 (ANN), KBC 11 (ANN), TVQ 71 (TX Network), KTN 81 (FNN/FNS), Rkb+ 41 (JNN), FBS 51 (NNN/NNS), CATV 111, and TNC 81 (FNN/FNS); along with its radio frequencies. In addition, the island could receive South Korean TV channels (KBS, MBC and SBS-affiliated KNN) and radio frequencies, due to its location nearby to the port city of Busan.
