parisisback10.jpg After being detained at Tokyo's Narita International Airport early Tuesday, Paris Hilton has returned home to Los Angeles. The heiress was held for six hours and questioned by airport officials just one day after she plead guilty to cocaine possession and obstructing an officer for her Las Vegas arrest last month.

Japan has strict immigration laws for those convicted of drug offenses, and though Hilton was there on business, it looks like this just wasn't the right time to go. Last night Paris tweeted, "About to take off. Going home now. So dissappointed to miss my fans in Asia. I promise to come back soon. I love you all! Love Paris xoxo"
