Tokyo: Asian champion Yoshihide Kiryu won the men's 100-metre title here on Sunday in the first track and field event held at the Tokyo 2020 Olympic Stadium.
Kiryu, who became Asia's fastest man in last year's Doha Asian Championships, clocked 10.14 seconds. Cambridge Aska, who was born in Jamaica to a Japanese mother and Jamaican father, finished second in 10.16.
The Tokyo Golden Grand Prix was originally scheduled to take place in May as a test event for the Olympic Games, which have been postponed by one year because of the Covid-19 pandemic.
The event was held behind closed doors and featured only Japan's top athletes. The brand new 60,000-seat stadium has staged just one football match since it opened last November.
