Well, there isn't a particularly large network of mosques in Japan, and I'm thinking that dusky fellers with beards and turbans might stand out just a little from the local population. Al Qaeda would have to try to ally with some of the domestic nut-cases, not that there aren't any of those (the guys gassing the subways come to mind) but I wouldn't lose any sleep over this one. Al Qaeda has threatened apocalypse in the U.S. for over two years now and its sum total of success is a little less than intimidating. They've been too busy talking big and dying elsewhere.

There is a substantial number of Iranians , Pakistanis , and other members of the Islamic faith living and working in the Tokyo/Kanagawa/Chiba / Saitama megalopolis . How many are connected with Al Quaeda is anybody's guess .
