This is the world in where One-Punch Man takes place. The planet is similar to Earth in many aspects but also possesses some drastic differences from the real world.


The World, unlike its real Earth counterpart, possesses a single super-continent instead of multiple large land masses. In the anime, it was shown that it has four natural satellites instead of a single moon.[1]

In addition to the super continent covering most of the planet, it possesses smaller islands and land masses that float in its immense ocean.[2]

The seven faced islands contains potatoes.[3]



The world is home to the human beings who are also the dominant species on the planet. It is also the place of multiple species of animals and strange creatures known as Mysterious Beings or Monsters.


  • The supercontinent in the world of One-Punch Man is shaped exactly the same as the Saitama Prefecture in Japan.
  • The person on the currency of the world is a Ball-Chinned man.
