Japan's Ai Fujinuma and Aya Umemura reached the quarterfinals after a fourth-round victory Monday over a Hong Kong pair in the women's doubles at the Athens Olympics table tennis tournaments.

Seventh-seeded Fujinuma and Umemura, who received a bye in the earlier rounds, beat Lau Sui Fei and Lin Ling 11-9, 6-11, 11-9, 12-10, 7-11, 11-7 to take a step toward becoming the first Japanese Olympic semifinalists in the event in 16 years.

On Tuesday, Fukuhara romped into the fourth round of the singles after a quick-fire 4-0 win over 10th-seed Jun Gao of the United States.
