Yui Kamiji Bio

Yui Kamiji is a Japanese professional wheelchair tennis player born on 24 April 1994 in Akashi, Hyōgo Prefecture, Japan. Competing on the international wheelchair tennis tour, she plays left-handed with a one-handed backhand and has built one of the most decorated careers in the sport. Over the course of her career, Kamiji has accumulated 33 major titles and reached the No. 1 ranking in both singles and doubles.

Kamiji first rose to global attention in 2014 when she partnered with Jordanne Whiley to complete the doubles Grand Slam, sweeping all four major titles in a single calendar year. She has since added Paralympic medals in singles and doubles, including a gold-medal sweep at the 2024 Paris Paralympics. She is currently managed by Avex Group through its Avex Challenged Athletes program.

Early Life and Background

Yui Kamiji was born on 24 April 1994 in Akashi, a coastal city in Hyōgo Prefecture, Japan. She grew up in Japan and developed her interest in tennis at a young age, eventually transitioning to wheelchair tennis as her competitive discipline. Her Japanese nationality and upbringing in the Hyōgo region have shaped her identity as one of the country’s most prominent Paralympic athletes.

Details about her family background and formal education are not widely documented in public sources, and she has generally kept her early personal life private. What is clear is that her early dedication to the sport laid the foundation for a professional career that would take her from regional Japanese events to the top of the international wheelchair tennis rankings.

Path to Professional Tennis

Kamiji’s rise through the wheelchair tennis ranks began on the international circuit in 2013, when she won singles titles in Iizuka, Daegu, Paris, and St Louis. That same season she became the first non-Dutchwoman to win the prestigious Wheelchair Tennis Masters singles title, signaling her arrival as a global force in the sport.

Her early doubles partnerships were equally productive. She won titles with Sharon Walraven in Pensacola, with Sabine Ellerbrock in Iizuka, with Ju-Yeon Park in Daegu, and with Jordanne Whiley in Paris and at the Masters. By the end of 2013, Kamiji had established herself as a versatile and dangerous competitor across surfaces and formats, setting the stage for her Grand Slam breakthrough the following year.

Yui Kamiji Career

Early Career (2013)

Kamiji’s 2013 campaign announced her as a serious contender on the wheelchair tennis tour. She won four singles titles across three continents and capped the year by becoming the first non-Dutch player to win the Masters singles crown. Her aggressive left-handed game and consistency from the baseline helped her adapt quickly to the demands of international competition.

In doubles, her willingness to partner with a range of players showed her tactical flexibility. She built chemistry with multiple partners while collecting trophies, demonstrating the team-oriented mindset that would later define her most celebrated partnership.

Grand Slam Breakthrough (2014)

The 2014 season was the defining year of Kamiji’s career. She won singles titles in Melbourne, Kobe, and Iizuka, reached her first Grand Slam singles final at the Australian Open, and then won her first Grand Slam singles title at the French Open at Roland Garros. She followed that breakthrough with a US Open singles title later in the year, establishing herself as a major champion.

Even more remarkably, Kamiji and her partner Jordanne Whiley completed the doubles Grand Slam in 2014, winning the Australian Open, French Open, Wimbledon, and US Open in the same calendar year. The pair added the Masters doubles crown at the end of the season, defeating Louise Hunt and Katharina Krüger in the final. While they did not go undefeated, losing a round-robin match to Marjolein Buis and Michaela Spaanstra, their overall achievement cemented their place among the sport’s great teams.

Continued Dominance (2015–2024)

Kamiji extended her Grand Slam success well beyond her initial breakthrough. She added Australian Open singles titles in 2017 and 2020, repeated her French Open success in 2017, 2018, and 2020, and lifted the US Open trophy again in 2017. She also reached the Wimbledon singles final in 2022.

In doubles, she and her various partners amassed an extraordinary haul of major titles, including multiple Australian Open, French Open, Wimbledon, and US Open crowns. She also added a second Wheelchair Tennis Masters doubles title in 2025, further underscoring her longevity at the top of the game.

Paralympic Career

Kamiji made her Paralympic debut in Rio in 2016, where she won a bronze medal in singles. Four years later at the Tokyo 2020 Paralympics, she claimed silver in singles and bronze in doubles, narrowly missing gold on home soil.

At the 2024 Paris Paralympics, Kamiji reached the top of the podium, winning gold medals in both singles and doubles. The double-gold performance represented the pinnacle of her Paralympic career and confirmed her status as one of the greatest wheelchair tennis players of her generation.
