China’s Liu Shiying is the new women’s Olympic javelin champion after her first attempt in Friday’s final was enough to secure the gold medal.
The 27-year-old, who threw a season’s best 66.34 meters, adds the Olympic title to her Asian Games gold and 2019 World Championship silver medal.
China have now won 36 gold medals at the Tokyo 2020 Olympics.
"It means a lot to me and my country. I want to thank everyone, my team, my country and also my parents," Liu said. “2020 was a very difficult year for me because of the injury and of the pandemic, but I got all the support and encouragement from all of them," she added.
She also said she was "very satisfied" with her performance.
"The most difficult thing for me was to have a breakthrough on my mind, although I improved my technique. But I didn’t have the opportunity to perform and get a better form (before)," she said.
Poland’s Maria Andrejczyk won silver with a throw of 64.61 meters with Australia’s Kelsey-Lee Barber taking bronze with 64.56m, her best performance of the season.

Elaine Thompson-Herah won her third gold medal of the Tokyo 2020 Olympics as Jamaica set a new national record to win the women’s 4 x 100 meter title on Friday.
Friday’s gold is Thompson-Herah’s fifth gold medal overall – the only woman to win more is American Allyson Felix with six golds.

Tokyo reached 34.8° C — or 94.6° F — on Friday, the hottest day of the Olympics so far and the hottest day of the year.
The heat combined with oppressive humidity yielded a heat index over 40° C, which is 104° F, through the afternoon.
This year's average high temperature during the games has been 33° C, or 91° F, two degrees above the average temperature for this time of the year — and, notably, two degrees above what the average max temperature would have been if the games were held on schedule last year.

Janja Garnbret became the first women's sport climbing Olympic champion after dominating the all-around competition on Friday.
The Slovenian, 22, was the hot favorite as the sport made its Olympic debut at Tokyo 2020 and she certainly didn't disappoint.
After a steady start in the speed climbing leg, she was the runaway winner in both the bouldering and lead disciplines.
Japan's Miho Nonaka and Akiyo Noguchi took silver and bronze respectively but neither could get close to Garnbret, who cemented herself as the best female climber in the world.
Garnbret spoke to CNN Sport ahead of the Games as she prepared for her first Olympics. Read more HERE.
With a bronze medal win in the 400 meter race, Allyson Felix has become the most decorated female track and field Olympian.
Felix has 10 medals across 5 Olympic games, matching Carl Lewis' US record.
She ran a 49.46, her second-fastest time ever. That was 0.05 seconds faster than the time she ran to win silver in Rio 2016.
The road to Tokyo has not been easy. Felix is an Olympic veteran used to pristine training conditions, but the last year has been very different. She trained on empty soccer fields and beaches.
Felix’s two-year-old daughter Camryn has also made a few appearances on the track as the Olympian has juggled motherhood and training.
“Having a young daughter at home, that’s a whole new world,” she told CNN previously. “It’s given me a different motivation.”

Shaunae Miller-Uibo of the Bahamas retained the women's 400 meter title in impressive fashion, as Team USA's Allyson Felix won bronze -- the 10th Olympic medal of her career.
With those ten medals, Felix passes Jamaican Merlene Ottey-Page for the most career Olympic medals by a female track athlete.
Silver went to Marileidy Paulino of the Dominican Republic.
Coming into the final, the starting eight were as impressive as we've seen, with Felix -- an Olympic legend -- and reigning champion Miller-Uibo headlining the group.
After an even first 200 meters, Miller-Uibo turned on the style.
An extremely strong back half of the race propelled her far in front of Paulino in second, allowing her to cruise over the line with a time of 48.36.
Paulino set a national record of 49.20, while Felix finished with a time of 49.46.
Correction: An earlier version of this post incorrectly identified the country Shaunae Miller-Uibo's was representing. Miller-Uibo was representing the Bahamas.
