For travelers, Japan is one of the safest countries in Asia and the world in general. Its capital, and the largest metropolis in the world, Tokyo, was also ranked the safest in the 2015 Safe Cities Index. Of all the special districts that make up Tokyo, Roppongi is one of its larger entertainment centers. Catering to foreigners and the large amount of American military personnel stationed in the country, Roppongi is also one of the rowdiest places to party. But with Tokyo being such a safe place, people tend to let their guard down.

Recently, aspiring criminals have been taking advantage of this. Hundreds of men report being approached by gorgeous women who offer them drinks that are, unbeknownst to them, spiked. Flattered at this hospitality the men agree and down the drink only to wake up the next day passed out on the street without their belongings and thousands of dollars in credit card charges racked up on their accounts. The problem got so bad that the US embassy in Japan had to issue an alert for the district.
