In the Edo period under the orders of the Tokugawa Shogunate, the man-made island of Dejima was constructed by the efforts of 25 influential merchants.
The construction was completed in 1636 and the Portuguese people became the first habitant of Dejima, however they were expelled from Japan in 1639.
In 1641 the Dutch Trading Post of Hirado was moved to Dejima.
Since then Dejima played the important role on the modernization of Japan as the only window to the Western for 218 years.
As Japan opened the country in 1859 the Dutch Trading Post was closed and to be converted into a foreign settlement in 1866.
After the Meiji period Dejima lost its shape resulted in the reclamation around Dejima in 1904.
In October 12, 1922, Dejima was designated as the national historical site “Former Dutch Trading Post on Dejima.”
In order to showcase the historical significance of Dejima to future generations, Dejima restoration project has been underway that had restored 16 of buildings from the early 19 century.
In November 2017 the Dejima Main Gate Bridge was completed that provides the path to Dejima from the Edo-mach.
