Thailand's mixed doubles duo Dechapol Puavaranukroh and Sapsiree Taerattanachai begin their hunt for the country's elusive Olympic medal in badminton today.
The third seeded pair are among the country's top hopes for medals at Tokyo 2020.
They made history in January when they claimed a hat-trick of Super 1000 titles in three consecutive weeks.
At Tokyo, Dechapol and Sapsiree are in Group B alongside France's Thom Gicquel and Delphine Delrue, Britain's Marcus Ellis and Lauren Smith, and Canada's Joshua Hurlburt and Josephine Wu.
The Thais play Hurlburt and Wu today.
The other Thais shuttlers in action today are Busanan Ongbamrungphan in the women's singles, and Jongkolphan Kititharakul and Rawinda Prajongjai in the women's doubles.
Busanan, the 10th seed, meets Daniela Macias today with the other player in Group D being Estonia's Kristin Kuuba.
Jongkolphan and Rawinda are in Group D with second seeds Chen Qingchen and Jia Yifan of China, South Korea's Kim So-Yeong and Kong Hee-Yong, and Bulgaria's Gabriela Stoeva and Stefani Stoeva, the European champions.
The Thais face Chen and Jia today.
Comeback king
Banned from the Rio Games for gambling and almost forced to retire last year after a car crash, Japanese badminton star Kento Momota is finally ready for his Olympic debut.
The world No.1 is among the host country's brightest medal hopes at the Tokyo Games, but he will just be glad to compete after fracturing his eye socket in a January 2020 accident.
Momota said his "spirit was almost broken" as he tried to recover from the crash -- hours after he won the Malaysia Masters -- which killed the driver of the vehicle taking him to Kuala Lumpur airport.
He suffered double vision and needed surgery on a bone near his eye that delayed his comeback, leaving him fearing his career was over.
"I thought about it. How long will it take?" he said in March last year, when asked if he was worried he might never play again.
"There were times when my spirit was almost broken."
But the 26-year-old has since made a full recovery, and he heads into his first-ever Olympics as the favourite to win the gold medal.
