Idk how to tell you this, but the Dai Nippon Teikoku is no longer the government of Japan. In fact, it isn't in charge of Korea or Nanjing, either. See what happened is they lost their two major cities. And every living creature within 1.3 Kilometers and soon after a lot of things adjacent to those areas. In seconds. They then surrendered and were occupied and restructured by the USA.

Pretty shocking for you to hear all of this for the first time, I'm sure.
