Currently, Japan serves as a sovereign state, with a maintained and unitary parliamentary constitutional monarchy, led by an emperor. It also appears as a highly skilled workforce and is among the most highly educated countries in the world. It is renowned for its historical and extensive cinema, influential music industry, anime, video gaming, rich cuisine and its major contributions to science and modern-day technology.

Regarding the villain tournaments, Japan appears in a minority in most of the tournaments' storylines.

That said, it appears as one of the central locations of the series.
