Paris Hilton was refused entry to Japan on Wednesday because of a drug conviction, immigration officials said.
The American celebrity socialite was expected to head back to the United States late Wednesday afternoon.
She had arrived in Japan on Tuesday and had been allowed to spend the night, to see whether immigration officials would reconsider their initial refusal to allow her entry. They stuck by their decision Wednesday, based on her having pleaded guilty to a drug charge earlier in the week in Las Vegas, Nevada.
Japan generally denies entry to foreigners who are on probation.
