JAKARTA (Kyodo) -- Hayato Katsuki won Japan's second straight gold medal in the men's 50-kilometer race walk at the Asian Games on Thursday.
Katsuki had to serve a five-minute penalty before the 34 km mark but rejoined the race and put in a spurt to cross the finish line at Jakarta's GBK Main Stadium in 4 hours, 3 minutes and 30 seconds, over three minutes ahead of China's Wang Qin.
"I'm relieved. I prepared myself well to beat the heat," said Asian Games debutant Katsuki, who secured a berth in next year's world championships with the victory.
"I'm happy with the gold medal but also know I have to improve on my walk form. I'm having mixed feelings," he said.
The gold was Japan's second in the event after Takayuki Tanii won at the 2014 Asian Games in Incheon, South Korea.
Japan is now the second country to have won the 50 km walk multiple times at the Asian Games, joining China which won its eighth total medal over this distance on Thursday.
Wang took silver in 4:06:48 and South Korea's Joo Hyun Myeong won bronze in 4:10:21.
Katsuki's compatriot Satoshi Maruo led for a majority of the race but faded to finish fourth.
