- Tsushima Province
Tsushima Province (対馬国; "Tsushima-no kuni") was an old province of Japan (-19c) on
Tsushima Island which occupied the area corresponding to modern-day Tsushima, Nagasaki. It was sometimes called Taishū (対州).Political History
The origin of Tsushima Province is unclear. It is possible that Tsushima was recognized as a province of the Yamato Court in the 5th century. Under the
Ritsuryō system, Tsushima formally became a province.Tsushima Province has been a strategic area that took a major role in the national defense against possible invasions from the continent and in trade with Korea. After Japan was defeated by Silla at the
Battle of Baekgang in 663,Kaneda Castle was constructed on this island.Tsushima Province had been controlled by the Tsushima no
Kuni no miyatsuko until theHeian Period . This clan was later replaced by the Ahiru clan. TheSō clan rose to power around the middle 13th century and seized control of the entire island in the late 15th century. During theEdo period , Tsushima Province was dominated by theTsushima Fuchu domain (Izuhara domain) of the So clan. It was put in charge of diplomacy and monopolized trade with theJoseon Dynasty of Korea.As a result of the
abolition of the han system , the Tsushima Fuchu domain became Izuhara Prefecture in 1871. In the same year, Izuhara Prefecture was merged into Imari Prefecture, which was renamedSaga Prefecture in 1872. Tsushima was transferred to Nagasaki Prefecture in 1872.Districts
Throughout history, Tsushima Province consisted of two districts:
*Kamiagata (上県)
*Shimoagata (下県)The capital of Tsushima province was located at Izuhara. In the modern local municipality system, they were divided into Kamiagata and Shimoagata districts respectively, and were subsequently merged into the city of Tsushima today.
