In 1974, Japan underwent the Separation: the southern part, including the main islands of Honshū and Kyūshū, were occupied by the United States, while the northern island, Hokkaidō (or Ezo, as it is called in the anime), was occupied by the "Union" (referring to the Soviet Union). Also in that same year, the Union began the construction of a strange tower on Hokkaido designed by a scientist named Ekusun Tsukinoe.
By the 1990s when the story begins, the U.S. occupation of southern Japan has ended, and the two nations have formed a pact called the Alliance. Hokkaido remains under the control of the Union. An underground group committed to reunifying Japan known as the Uilta Liberation Front exists in the South.
