I'd say Korea has a much better claim to that title these days, although aside from Gangnam Style, the hallyu hasn't made that much of a dent on the United States.

Where in a closeup of the girl'a head she's shown with tareme eyes and ahoge hair, the latter a clue that she's foolish in some way (so is Belldandy). The artist DK clearly understood and used this visual language.
That the Japanese also like Disney flicks, or echoing jmole, stuff from Korea, is hardly remarkable.
It's a big step forward from the Otaku subculture that is generally associated with anime, and I think that's a good thing; my biggest impression upon visiting Japan was not the overwhelming craziness usually associated with it, but the fact that they're a society that's already encountered its population peak, and (for the past two decades) a corresponding slide into recession and deflation.
The US and other first world countries would be wise to look at Japan for both a model to follow, and a series of pitfalls to avoid, because we'll all face the same issue in due time. Culture (pop or otherwise) is an important messenger of the values a society holds dear.
Perhaps the most enlightening aspect of Japanese culture is our media's obsession with some of the certain "odd qualities" that it espouses. The morbid fascination we collectively seem to have with the weirder parts of Japanese culture certainly seem to point fingers at weaknesses within our own. Hentai is almost glorified, while the tiny 8 oz beverage cans in almost any vending machine are ignored.
While absolutely not a perfect society in a multitude of ways, the Japanese do get a lot of things right. I think the normalization we're seeing is a good step toward learning more valuable lessons, and more importantly, being receptive toward those lessons.
Only weird nerds know about japanese cartoons and comic books.
And anime/manga is becoming more and more mainstream. Sure it's not like you'll walk in on your boss catching up on the latest episode of Attack on Titan but it's getting there.
