Manga, Anime, and the World
Small or large adjustments in Japanese customs are made for non-Japanese viewers. For example, characters eat onigiri. In Western versions, they change onigiri to cookies. However, they do not change the pictures in manga and instead add short explanations. This way, foreign readers can understand Japanese customs.
An example of a large adjustment can be found in the 1970s anime Kyojin no Hoshi. The main character Hyuma becomes a professional baseball player. In India, they changed the sport to cricket, which is a popular sport in the country.
Anime became more popular due to these adjustments to fit each culture.
