I live there, so yeah, I've been.
Its not all anime and pocky.
Its racism and awkwardness.
They hate foreigners, their culture is based around being awkward in front of other people, and deep down inside most of them is a lunatic waiting to come out.
I've lived here for over a year now and I've seen the sights. Tokyo is cool. Climbing Mt. Fuji was nice. The Cherry Blosom festival at Hirosaki castle was pretty. But thats really the problem. The country is beautiful, but because i'm a foreigner (5'10" 230lbs of military) I stand out, people notice me, and immediately tag on the stupid problem causing asshole stereotype.
My year here has been interesting, but once I leave I probably won't come back.
