The islands has been a sub-prefecture of Tokyo, Japan before Doomsday, and were sparsely populated and has their own distinct dialect, culture, and even appearances. All of that changed on Doomsday, when the capital of the prefecture, as well as capital of the nation, Tokyo was nuked by a Soviet Missile, along with other cities such as Nagasaki. In 1993, help came in the form of Hawaii. An expedition had been sent to the island and they reported conditions as being horrific. The Hawaiians eventually evacuated every living soul, which was around a mere 900, back to Hawaii.
