Paris Hilton's recent drug charges have had far-reaching consequences.
Having pleaded guilty to cocaine possession and obstructing an officer on Monday, the 29-year-old has been refused entry to Japan.
Paris had flown there on a business trip with her sister following her court appearance.
Upon landing at Tokyo's Narita airport, she was questioned for six hours by Japanese immigration officials, and asked to stay overnight in a nearby hotel, while it was decided how to handle her case.
Under Japanese law, immigration authorities have the power to deny entry to visitors who have been convicted of drug-related offences.
Paris had been scheduled to appear in a news conference on Wednesday to promote her fashion and fragrance lines.
Having previously posted a photograph of herself and younger sister Nicky arriving in Tokyo (left), Paris later wrote on her Twitter page: "About to take off. Going home now.
"So disappointed to miss my fans in Asia. I promise to come back soon. I love you all! Love Paris xoxo"
