Penang, cross-border schooling and Singapore
Jason Teh, recorded in international draws as Jia Heng Jason Teh, was born in Penang, Malaysia, on 25 August 2000. He first accompanied his father to badminton courts as a child. After the family moved to Johor Bahru, school in Singapore meant early-morning Causeway crossings and afternoon journeys back for training.
His education included Montfort Junior School, Bowen Secondary School and Singapore Sports School. In a 2024 CNA interview, Teh recalled leaving school after Secondary 4, completing National Service and choosing full-time badminton. His family settled in Singapore in 2017, and he became a citizen in 2019.
National titles and experience beyond singles
Teh won the Singapore National Open men’s singles title in 2020, beating Vega Vio Nirwanda in the final, and retained the title in 2021. Those victories established him as a national champion before his international World Tour breakthrough.
He also represented Singapore in team competitions. The school’s major-games record lists Birmingham 2022 mixed-team bronze, a result separate from an individual singles medal. In October 2024, he told CNA he was learning to approach matches more patiently.
The Thailand Masters breakthrough in 2025
On 2 February 2025, Teh defeated China’s Wang Zheng Xing 21–18, 15–21, 21–19 to win the Thailand Masters in Bangkok. It was his first BWF World Tour title, at Super 300 level. The three-game final turned a run of near misses into a documented international championship.
SBA’s post-match account explains how narrow the finish was. Teh recalled rushing when the deciding game reached 18–18, then resetting his attention. Vega Nirwanda guided him at the venue while Kim Ji-hyun supplied remote match analysis during the tournament. Teh credited Nirwanda’s courtside guidance and Kim’s daily analysis as part of his tournament support.

A second Super 300 title in Korea
Teh won the Korea Masters on 9 November 2025, beating Japan’s Yudai Okimoto 21–14, 21–15 in Iksan. He did not drop a game in five matches. The result was his second Super 300 title of the year, distinct from the three-game struggle that had brought his first.
The federation’s report also records multiple early exits between the two titles. Teh spoke about coping better with pressure and treating each match on its own terms, even as the top seed. The intervening defeats matter: the second championship followed an uneven season, rather than an uninterrupted rise after Bangkok.

The 2026 Polish Open and tournament levels
On 22 March 2026, Teh won the Polish Open in Łódź. The Polish Badminton Association records a 21–9, 21–10 final victory over Koshiro Moriguchi, while Badminton Europe independently reports his title. It was another international singles success, but the International Challenge event was not a third BWF World Tour Super 300 championship.
National Open titles, Commonwealth team bronze and individual international championships represent different competitions. The wins in Bangkok and Iksan marked his progress from domestic success to the World Tour, while Łódź added a title on the European circuit.
