Anime, manga, kimonos, saying "Kawaii." We all love it.
Either openly or secretly. But unless you can truly speak japanese, or actually know about their culture, then don't even attempt to act Japanese. This means, if you've learned evrything you know from anime, and you think everyone on the entire continent of Asia A:runs around with giant swords, B: is a ninja, or C: has a tail and animal ear atop their heads, or D: 'All of the Above and much, plus they live off of ramen. it's their strict diet." you may need to study up a bit more. ^^
And I mean this by no offense towards every single fan girl/boy out there. If you're just the person who explodes every time someone mentions anime, that's fine. Anime is made of win.

And if you actually DO know Japanese, sure okay. I mean, it's not like your forbidden to speak it. Deviantart is an incredibly diverse community of artists. I just mean don't run around saying things that may not even make sense.
Just don't try to act like something/-one you're not. :/
I don't get that "asian-hype" either..
JK...this really made me laugh. Awesome. (Ever met a Westerner who talks like they have a slight Japanese accent? If not, yeah they're out there...drives me up the wall, lol.) I like Japan--I've been there four times--and I totally dig this stamp.
