"It's nice to be top seed and win a tournament -- it's the first time I've achieved that," said Bartoli. "Roger Federer may be used to it because he's always number one but I'm not."

World number one Federer was playing Britain's Tim Henman in the men's final later on Sunday.

Bartoli's victory in Tokyo improved her record since last month's U.S. Open to 13 wins in 16 matches and was worth $28,000 in prize money for the world number 22.

Her first title came in Auckland at the start of the year. Bartoli was also a finalist in Bali last month.
