Batman is clearly trying to throw everyone off. First his signal shows up in suburban Illinois, and now it's been spotted over in Japan. According to Stars and Stripes, the larger-than-life Batman symbol has been on the roof of a U.S. Air Force Base over there since the 1980s. They report there's been no sign of the caped crusader, however, and only F-15s have been spotted, no Batmobiles. Alright, there's got to be a hidden Bat Signal somewhere in the five boroughs—this is the real Gotham City, after all. [via NY Post]
