Ai Ueda and Yuichi Hosoda each won a gold medal on Thursday at the Asian Games as Japan claimed the top two prizes in both the women's and men's triathlons.

Ueda won a Japan one-two finish in the women's triathlon, and Hosoda, the defending champ, did the same in the men's event a few hours later, when he pipped teammate Hirokatsu Tayama at the finish line by 13 seconds to complete his race in 1 hour, 49 minutes, 11 seconds.

It was the second straight Asian Games in which Japan took the top two spots in both triathlons. Mariko Adachi and Akane Tsuchihashi won gold and silver in Guangzhou, China, four years ago, when Ryosuke Yamamoto joined Hosoda on the men's podium.
