Police said a number of counterfeit $100 bills have been passed at currency exchange shops in Tokyo's Shibuya district.
In the latest incident, on Monday, an employee of a currency exchange business discovered that a counterfeit $100 bill was brought to the store sometime over the weekend, Fuji Tv reported.
According to police, since mid-October, multiple reports have been filed by currency appraisal experts about bogus bills being passed. Police have subsequently found dozens of fraudulent bills and are trying to trace the route by which the forged currency began circulating.
According to Tomohiko Endo, an expert on counterfeit detection and currency appraisals, several "foreign-looking men" visited a currency exchange shop in Shibuya on Oct 27 and exchanged several fake $100 bills for Japanese yen.
Endo said the bogus bills he has seen so far are almost impossible to detect and that they can pass inspection on a magnetic reader.© Japan Today
