Paris Hilton was not allowed to stay in Japan today, two days after she pleaded guilty to a drug charge in Las Vegas.
Japan has strict immigration laws that bar entry to those convicted of drug offences, although exceptions are occasionally granted.
"I'm going back home, and I look forward to coming back to Japan in the future," Hilton told reporters before departing on her private jet.
The 29-year-old celebrity socialite had been due to appear today at a news conference in Tokyo to promote her fashion and fragrance lines. She arrived yesterday evening, but was stopped at the airport and spent the night at an airport hotel after being questioned by officials.
A Japanese immigration official said Hilton was denied entry after a total of about six hours of questioning.
She also abruptly cancelled planned appearances in Kuala Lumpur, Malaysia, and Jakarta, Indonesia.
