Janice Tjen Bio
Janice Tjen (born 6 May 2002) is an Indonesian professional tennis player who has quickly become one of the most decorated competitors in her country’s history. She reached a career-high WTA singles ranking of No. 53 on 3 November 2025 and is currently the No. 1 singles player from Indonesia. Tjen has won one WTA Tour singles title and multiple doubles titles, including breakthroughs at the 2025 Chennai Open and other international events. Standing 1.71 m tall, she plays right-handed with a two-handed backhand and is coached by Chris Bint.
Born and raised in Jakarta, Tjen turned professional in 2018 and developed her game through the United States college system before returning to the international circuit. Her combination of steady baseline play and composure under pressure has carried her into Grand Slam main draws and WTA finals. She is also a medalist at the 2022 Asian Games, where she won bronze in women’s doubles.
Early Life and Background
Janice Tjen was born on 6 May 2002 in Jakarta, Indonesia. Growing up in the Indonesian capital, she was introduced to tennis by Priska Madelyn Nugroho, a close friend and one of the country’s top junior players at the time. That early encouragement from a fellow competitor played a significant role in shaping her career path and helped Tjen fall in love with the sport.
Because of the high costs associated with turning professional at a young age, Tjen and her family decided to develop her skills through college tennis. After finishing high school, she enrolled at the University of Oregon, where she played for one season before transferring to Pepperdine University in 2021. She graduated from Pepperdine in 2024 with a degree in sociology, balancing her academic commitments with a steadily rising competitive profile.
Path to Tennis
Tjen’s competitive path began in earnest when she made her multi-sport event debut at the 2019 ASEAN School Games in Semarang, Central Java. She won a gold medal in singles and a silver medal in doubles at the tournament, signaling that she could compete at a high level on an international stage. The experience helped build her confidence and added early silverware to her résumé.
While competing in college tennis in the United States, Tjen also represented Indonesia in team competition, making her Billie Jean King Cup debut at age 18 against China at the 2020–2021 Asia/Oceania Group I qualifying event in Dubai, United Arab Emirates. That exposure to senior-level international play, combined with strong showings in NCAA competition, prepared her for a smoother transition to the WTA Tour.
