TOKYO - Paris Hilton left Japan on Wednesday after lengthy questioning from airport officials, and following media reports that the socialite would not be allowed into the country after pleading guilty to possessing cocaine.
Hilton, 29, had flown into Tokyo on Tuesday for a fashion show but had been held back by officials at Narita airport so they could decide whether to allow her into Japan.
In Japan, immigration authorities can deny entry to anyone convicted of drug-related offences.
Hilton dropped her request to enter the country after questioning by officials, Kyodo news agency said. A spokesman at the airport's immigration bureau declined to say whether she had been barred entry or if she was leaving on her own will.
"I'm going back home. I look forward to being back in Japan in the future," the celebrity heiress said.
"I'm really tired," she told reporters at the airport.
On Monday in Las Vegas, Hilton pleaded guilty to cocaine possession following a recent arrest in which she was found to have 0.8 grams of the drug in a purse.
She was given a one-year suspended sentence, fined $2,000 and ordered to do community service.
Hilton arrived in Japan on a chartered plane with her sister Nicky. Airport officials asked her to stay at an airport hotel overnight so she could be questioning, Kyodo said.
She had been due to appear at a fashion show on Wednesday in Tokyo's Roppongi entertainment district but the show was canceled.
The former star of reality TV show "The Simple Life" is a member of the family that founded the Hilton hotel chain, and she has parlayed her notoriety into a successful career endorsing products in fashion, fragrances and other industries.
In Japan, she has promoted a popular brand of bags in the past with her sister.
