Earth

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

Description
The world, unlike its real Earth counterpart, possesses a single super-continent instead of multiple large landmasses. In the anime, it was shown to have four natural satellites instead of a single moon.

In addition to the supercontinent covering most of the planet, the World possesses smaller islands and landmasses that lie in its immense ocean.

The "seven faced islands" contain potatoes.

Trivia

 * The shape of the planet's supercontinent is the same as the Saitama Prefecture in Japan. This is the prefecture that One-Punch Man author ONE was brought up in.
 * The currency of the world is nearly identical to the real-world Japanese yen, but features the face of a ball-chinned man (possibly an ancestor of Agoni and the Ball-Chinned Kid) instead of Fukuzawa Yukichi.
