After World War III and World War IV, a massive shifting of population occurred all over the globe. Hundred of thousands of non-Japanese citizens found themselves on Japanese soil, either from a failed invasion, or fleeing from their own countries. Many, those with applicable skills and training and advanced cyberbodies, were permitted visas. Others gained full citizenship, leading to the more colorful demographic of Japan’s society. However, hundreds of thousands still remained. The Special Refugee Treatment Act was formed and locations around Japan (mostly no-man land and old radiation zones cleaned up after the Japanese Miracle) were set aside and fenced. The refugees were permitted to live independently in these zones. However, they could not enter Japan without proper permits or Visas. In many ways, these Sectors became autonomous nations, under no leadership, with no way to support themselves. None of the people in these sectors wants to return to their countries (if they existed), so they remained…for years.
There are five residential refugee relief sectors in Japan. Mostly with Chinese refugees. One is located in Niihama. The largest one in Kyushu is better known as Dejima Camp or Dejima Island. Another sits in Kanto and the other in Shinjuku—where part of old Tokyo resides in the camp. The last is in Nagasaki. Homeless people, with nowhere else to go, often hide in Refugee Relief Sectors. These sectors often supply a cheap labor force to major cities like Kyushu. Dejima Island stands out from other districts. Unlike other districts, which recycles other facilities, it was a floating industrial island, built only for its purpose, connected to the mainland, by a very long bridge. This bridge remains the only passageway and method of wired communication between the island and the rest of Japan.
