American (super hero) comics
The Japanese name for comics 漫画 manga (漫 funny + picture 画) has become an international word, but we still use a foreign word to refer to foreign things.
アメコミ amekomi is short for American Comic アメリカンコミックス(amerikankomikkusu)
Japan is sometimes very conscious of the split between occidental and oriental.
We say 邦画 houga for Japanese and east Asian films, and 洋語 youga for western/European films.
Although many Japanese children grow up with a view of the world that it is made of two countries 日本 Japan and 外国 foreign land(s), we are actually very sensitive about where things come from.
