Japanimation

They haven't got any cuddly animals — in fact, there's nothing warm and fuzzy about them. But that isn't stopping Japanese anime cartoons from becoming hot video imports. Anime (pronounced ''Annie May'') has its roots in the popular serialized comic books (manga) that sprouted post-Hiroshima. Bizarre sci-fi fantasies — none weirder than Project A-Ko, a raging interplanetary cat fight — dominate the genre. But it also embraces soap opera and even sex-happy ''love comedies.''
