In the 12th century, the samurai class emerged in Japan, with warriors serving as protectors for the aristocracy.

Shonen Jump, a weekly manga magazine published by Shueisha, has been a major influence on the development of anime and manga culture in Japan, and has produced many popular anime series such as Dragon Ball, One Piece, and Naruto.

The population of Japan is over 126 million people, making it the 10th most populous country in the world.
