OSAKA - A 37-year-old Chinese woman has been arrested and referred to prosecutors on suspicion of operating an unlicensed taxi service that transported travelers from Kansai International Airport to a hotel in Kyoto. A news crew documented the police operation at Kansai International Airport on July 7. The passengers showed investigators a smartphone displaying the names of destinations across Japan, along with an entry advertising transfers from Kansai International Airport. Unlicensed taxi services have become a persistent problem around Kansai International Airport over the past decade. In one case detected last year, a vehicle licensed only to provide nursing-care taxi services was used illegally to carry tourists.
