My blog has been getting periodic pings about rumblings in Roppongi: Tokyo cops cleaning out pesky foreign touts before Olympic inspectors see them; the U.S. Embassy warning Americans to stay away from the area after reports of drugged drinks and thefts.
The latter was particularly embarrassing (coming from the Americans, of all people) given Japan's reputation for having the world's safest streets. So police have begun reasserting their control, cracking down on — you guessed it — foreigners. And where might you find them? You guessed that too.
I heard about police raids in Roppongi in May and June. But now they are going beyond ID checks for visa overstayers. Regular customers have been apprehended for drinking while foreign, bundled into police vans and shuttled off to HQ for urine tests for drugs. According to their associates, those testing positive for controlled substances have been deported.
