Selena Gomez arrived to find hundreds of screaming fans lining the airport terminal in Tokyo, Japan on Sunday morning (February 20).

The 18-year-old teen star showed off her adorable smile as she trekked through Haneda Airport after the 5 a.m. landing.

Onlookers tell that security was taken by surprise by the mob scene - as they had only planned for about 20 fans because of the earliness of Miss Gomez's arrival.

As for the Asian venture, Selena is in Japan to promote her new album "A Year Without Rain" and her Disney Channel show "The Wizards of Waverly Place".
