I was in Japan over the summer and I didn't notice any animania really out of the ordinary. I mean, the pervs reading hentai mags on the subways is old news.
In Japan, unless you're a kiddie, anime is not really the "hip" thing to be into, despite the fact that it remains more common there than American animation is here in the United States (also probably the reason most anime studios are broke). While manga abounds like sushi on every street corner, anime is still considered generally considered a kids novelty; if an adult in his twenties said to his peers, "I love anime!" he'd get some weird stares, and might even be branded an "otaku" (used widely in Japan in a negative sense, as opposed to the idealistic positive way we toss it around in America).
