There's an easy way to do this. Look up the Hangul "alphabet" and you'll be able to recognize Korean. Look up katakana and hiragana too. If you see any of those symbols, it's Japanese. If it just looks like a mess of complex blocks with no simple alphabet, probably Chinese.
Watch out anon, he might like that.
I think that's Metro. They also showed up in the early riot days.
