GUANGZHOU, China (Kyodo) -- Japanese Olympic champions Ayaka Takahashi and Misaki Matsutomo captured their second badminton's World Tour Finals championship in women's doubles on Sunday.
Takahashi and Matsutomo, the top seeds, beat Lee So Hee and Shin Seung Chan of South Korea 21-12, 22-20 to win their first finals title in four years. Lee and Shin had reached the final by defeating world champions Mayu Matsumoto and Wakana Nagahara of Japan.
"We kept our poise and won out in the end. This is meaningful as we head into next year," Takahashi said after beating the South Korean pair for the fourth time in nine matches.
Earlier, Japan's Kento Momota and Nozomi Okuhara crashed out in the finals of the men's and women's singles, respectively.
Momota, the world's top-ranked men's player, lost to second-ranked Shi Yuqi of China 21-12, 21-11.
"I became timid and stayed that way, but that was because he began dictating the action," Momota said. "Today my opponent was superior to me in every area."
World No. 5 Okuhara fell to sixth-ranked Indian P.V. Sindhu, 21-19, 21-17. The 23-year-old Japanese, who beat Sindhu to become world champion in 2017, failed in her bid to regain the tour final championship she last won three years ago.
"The accuracy of my shots was way too poor. I could never get the initiative," said Okuhara, who has recently been hobbled by shoulder and knee injuries.
In the men's doubles final, Japan's Hiroyuki Endo and Yuta Watanabe lost 21-15, 21-1 to China's Li Junhui and Liu Yuchen.
