Paris Hilton has flown back home to Los Angeles after she was barred from entering Japan.

The 29-year-old heiress was detained at Tokyo's Narita International Airport early Tuesday -- a day after she agreed to plead guilty to cocaine possession in Las Vegas to avoid jail time.

Japan has strict immigration laws that bar entry to those convicted of drug offenses.

Hilton -- who was set to participate in a fashion show and promote her perfume line with sister Nicky -- Twittered that she was disappointed she had to leave and "miss" her fans in Asia.

"I promise to come back soon," she vowed. "I love you all! Love Paris xoxo."
