This is a good question but it is also difficult to answer because each country has some degree of inspection. For example, animation or manga is recently considered as a Japanese culture. However, some of manga products or animations in Japan are forbidden in some countries. Doraemon is one of them. In the US, it is not a popular animation at all because of the concept of the animation such as the major story line which the laziness of the main character is supported by his robotic cat and also including bullying situations between the friends. The US consensus thinks that this is not appropriate for American children. Thus they do not want to broadcast this animation in this country. The regulations and laws will be different in each country. Therefore, there may be more cultural elements which are not world-widely shared in Japan.
