U.S. celebrity socialite Paris Hilton left Japan Wednesday after authorities banned her from entering the country due to her recent drug conviction.

Hilton flew out of Tokyo's Narita Airport aboard a private airplane the day after arriving for a promotional tour for her fashion designer business.  She underwent several hours of questioning by immigration officials Tuesday and Wednesday before dropping her request to enter Japan.

The 29-year-old heiress to the global Hilton hotel chain pleaded guilty Monday in Las Vegas to a charge of possessing a small amount of cocaine, for which she received a suspended sentence.  Japanese immigration laws forbid anyone convicted of drug-related charges from entering the country.

Shortly before leaving Tokyo, Hilton sent out a message via the social networking site Twitter that she was disappointed "to miss my fans in Asia."
