The Toyota Thailand Open was a badminton tournament that took place at the Impact Arena in Thailand from 19 to 24 January 2021. It had a total purse of $1,000,000.
The Toyota Thailand Open was the ninth tournament of the 2020 BWF World Tour and also part of the Thailand Open championships, which had been held since 1984. This tournament was organized by Badminton Association of Thailand and sanctioned by the BWF. It was the second of three BWF tournaments taking place in Thailand in January 2021 following a break caused by the COVID-19 pandemic. Participation in both Thailand Opens was mandatory to qualify for the 2020 BWF World Tour Finals.[1]
Four out of five world number ones withdrew from all three tournaments. The Chinese team withdrew from all three tournaments after failing to get permission to travel to Thailand; affected players include Chen Qingchen and Jia Yifan (women's doubles), and Zheng Siwei and Huang Yaqiong (mixed doubles).[2] In addition, the Japanese team has withdrawn from the tournaments following the positive COVID-19 diagnosis of Kento Momota (men's singles).[3] Following Kevin Sanjaya Sukamuljo's positive COVID-19 diagnosis, he and Marcus Fernaldi Gideon (men's doubles) withdrew from the tournaments.[4] Indian men's singles players B. Sai Praneeth and Kidambi Srikanth had to pull out after Praneeth's positive COVID-19 diagnosis.[5]
This international tournament was held at the Impact Arena in Pak Kret, Nonthaburi, Thailand.[1]
