Uzbekistan’s Ulugbek Rashitov, the United States’ Anastasija Zolotic and Croatia's Matea Jelić are the other three athletes who won in Japan last year, scheduled to appear in the second leg of the series.

Wongpattanakit is one of the headliners competing in the women's under-49 kilograms event, alongside Olympic silver medallist and Rome Grand Prix winner Adriana Cerezo of Spain.

Serbia's Tijana Bogdanovic and Israel's Abishag Semberg are also expected to fight, making it a stacked division.

Rashitov, who won the men's under-68kg class at the Olympics, is set to fight for gold in the category again as he seeks to prevent Hakan Reçber of Turkey from winning back-to-back Grand Prix events.

Reçber, a Tokyo 2020 bronze medallist, and Rashikov may also need to keep an eye out for Olympic silver medallist Bradly Sinden with the Briton also seeking to claim the title.

Meanwhile, Zolotic is among the athletes lined-up for the women's under-57kg alongside fellow Olympic medallist Hatice Kübra İlgün of Turkey and China's Luo Zongshi.

Jelić, prepped to compete in the women's under-67kg event, could face a challenging task of bettering Britain's Lauren Williams, who she defeated in Tokyo last year, and Ivory Coast's Ruth Gbagbi.

Sarah Chaari of Belgium may also prove to be a tough opponent to beat as a recent world junior champion while home favourite Magda Wiet Henin is bidding to follow up her Rome Grand Prix triumph.

In the men's under-58kg category, South Korea's Jang Jun is tipped as one of the favourites after his Olympic bronze medal is backed up by winning in the Italian capital.

However, Olympic silver medallist Mohamed Khalil Jendoubi has the skill to lead Tunisia to glory.

Jordan's Saleh Elsharabaty, Egypt's Seif Eissa and Croatia's Toni Kanaet all come into the men's under-80kg event as Olympic medallists and are expected to impress with Rome Grand Prix victor Simeone Alessio of Italy.

In the men's over-80kg class, Turkey's Emre Kutalmış Ateşli enters the competition in red hot form after winning in Rome and may need to battle Olympic bronze medallist Rafael Alba of Cuba for supremacy.

South Korea's Lee Da-bin has the same triumphant feeling having won the first World Taekwondo Grand Prix in the women's over-80kg division.

Potential challengers to the Olympic silver medallists are Olympic bronze medallist pairing, Bianca Walkden of Britain and Althéa Laurin of France.

The competition is due to run from tomorrow to Sunday (September 4).
