The first Refugee Residential District that is displayed on the map of Japan is Dejima, which Batou briefly mentions. Dejima is an artificial island in the Bay of Nagasaki that had been, from 1641 to 1853, a Dutch trading post. During the time of its use for trade, the Dutch had near exclusive rights to barter with Japan. However, the Dutch living on Dejima were not allowed to leave the island.
The second Refugee District that is displayed on the map is located near New Port City. It's the place that has the huge abandoned buildings seen at the beginning of "MACHINES DÉSIRANTES" and where the Chief goes to find information about his brother's arrest in "SCANDAL". See the second note to "SCANDAL" for location of New Port City. The third Refugee District is near Tōkyō and the fourth and fifth Districts are located on the island of Hokkaidō.
