I dunno who this guy is, but he's "wanted", whoever he is.

He's got a missing left digit indicating former (ie disgraced) lower gangland connections clearly outlined on the poster.

Thing is I haven't seen this poster anywhere other than Toei Shinjuku line or Hanzomon line ,since its limited to the subway I'm guessing he's a bum fiddler on crowded trains, added to my initial kanji misreadings, I interpreted him as a "chikan" - 痴漢 - meaning "pervert" as the sound "chi" (the latter part of his name) looks like 地.(see the poster and do the math...)

Funnily though the two kanji that make the words pervert in Japanese individual meanings are "foolish" and "sino" or "Chinese"...offensive no ?

Whoever he is, if YOU are travelling on shinjuku line, be on the look out for an ex yakuza Chinese pervert and turn him in so that regular fully digited Japanese men can hassle girls in short skirts...But seriously I wonder what a bedragled looking tierd guy like this could have done to have sparked so many wanted posters ?
