"I know nothing about her because she has never appeared in a major tournament," Fukuhara said.

But she said that the defeat will not affect her preparation for the doubles match later on Wednesday.

"I should adjust myself to the doubles in the evening," she said.

Fukuhara shocked table tennis world by reaching the last eight at the 2003 Paris world championships at the age of 14. But that remains her best singles feat in the world championships.
