JAKARTA (Kyodo) --In the men's 100, Ryota Yamagata matched his personal best of 10.00 seconds to finish third behind China's Su Bingtian. The Chinese ran a games record 9.92 seconds to win gold with Qatar's Tosin Ogunode taking silver with an identical time to Yamagata.
"To be honest, I feel a little regret," Yamagata said. "But the start was good, and for the race as a whole, I did all I could. I am glad I could win a medal."
Su said his time was not a motivation.
"I didn't care about time," he said. "All I wanted was gold."
Japan's Asuka Cambridge bombed out in the 100 semifinals, he blamed a poor start and his inability to accelerate mid-race for his 10.36-second time, the 11th fastest.
Edidiong Odiong from Bahrain won the women's 100, her 11.30-second time just enough to beat out Dutee Chand from India and Wei Yongli from China.
Japan's first medal hope of the night, Julian Jrummi Walsh, finished a distant fifth in the men's 400, won by Abdalelah Hassan of Qatar.
The Jamaican-Japanese Walsh was close to the leaders exiting the final bend, but the Sudan-born Qatari turned on the jets to cross the line in 44.89 as Walsh went backwards. India's Muhammed Anas Yahiya won silver and Bahrain's Ali Khamis bronze.
"I was reminded of the strength of the athletes in Asia," said Walsh. "I brought my best, and this is the reality. I think it will definitely lead to me raising my game."
Yuki Hashioka was fourth in the men's long jump, his 8.05-meter leap just outdone by bronze medalist Sapwaturrahman Sapwaturrahman of Indonesia, who registered a personal-best 8.09. China went one-two, Wang Jianan's games-record 8.24 jump too good for Zhang Yaoguang.
Bahrain won gold in the women's 400, 2017 World Championships silver medalist Salwa Naser crossing in a games record 50.09 seconds with India's Hima Das and Kazakhstan's Elina Mikhina winning silver and bronze, respectively.
There were more medals for Bahrain in the men's 10,000, Hassan Chani outlasting teammate Abraham Cheroben with China's Zhao Changhong winning bronze.
Gong Lijiao of China won women's shot put gold. The reigning champion and two-time Olympic medalist was in another league as she threw 19.66 meters, more than two meters further than countrywoman and silver medalist Gao Yang. Noora Jasim of Bahrain won bronze.
South Korea's Jung Hye Lim won women's 100 hurdles gold in 13.20 seconds, beating Indonesian Emilia Nova and Lui Lau Yiu from Hong Kong who both set personal bests.
Japan claimed its first track and field gold on Sunday when Keisuke Ushiro ran a heroic 1,500-meter race to win the men's decathlon.
Entering the event's final discipline, the 32-year-old defending champ was two points behind Suttisak Singkhon of Thailand, needing to outpace him over the almost four laps of the GBK main stadium to claim gold.
By finishing the 1,500 in third, he scored 655 points and built a 69-point final buffer over the Thai. Ushiro's fellow Japanese Akihiko Nakamura won the 1,500 to snatch bronze from China's Gong Kewei.
"I'm really happy with this," said Ushiro, who won the decathlon's three throwing disciplines and the pole vault. "I'm at an age, 32, where I'm called a veteran, but that is just a number. I want to win a medal in a world competition, and Tokyo 2020 is coming up, so I aim to keep striving."
