Asian champion Bao Chunlai and defending champion Wang Yihan collected both the men's and women's singles titles of the badminton Japan Open for China on Sunday.

Unseeded Bao crashed Athens Olympic gold medallist Taufik Hidayat of Indonesia 21-15, 21-12 in the women's singles final after Wang Yihan eased past Chinese teammate Wang Xin 21-8, 21-9 for the women's singles crown.

"Today I played the very best of myself," said Bao, the runner-up here in 2004.

It was the 26-year-old's fourth title of the season, following victories in the German Open, the Asian championships and the Singapore Open.

"Without Lin Dan and Chen Jin here this week, I was alone with Chen Long and played against none teammates, which made me more comfortable," he added.

Bao had previously eliminated third seed Peter Gade of Denmark and eighth seed Tien Minh Nguyen of Vietnam.

Wang Yihan has claimed her fifth title of the season here, after the All England, German Open, Swiss Open and Macau Open crowns.

"I'm very happy to win the title for a second year running," said the 21-year-old. "I think both of us played our very best, though we know each other very well."
