“Dejima (Japanese: 出島, “exit island”) was a Dutch trading post located in Nagasaki, Japan from 1641 to 1854.[1] Dejima was a small fan-shaped artificial island in the bay of Nagasaki covering an area of 120 m × 75 m (390 ft × 250 ft) or 9,000 m2 (2.2 acres), and is listed in old Western documents Latinised as Deshima, Decima, Desjima, Dezima, Disma, or Disima. Dejima was built in 1634 to house Portuguese traders and separate them from Japanese society by digging a canal through a small peninsula. The Dutch were moved to Dejima in 1641 and during most of the Edo period the island was the single place of direct trade and exchange between Japan and the outside world. Dejima was abolished after the Treaty of Kanagawa in 1854 and the island was later integrated into Nagasaki city through land reclamation. In 1922, the “Dejima Dutch Trading Post” was designated a Japanese national historic site.” Wikipedia
