Akira Santillan (アキラ サンティラン, Santiran Akira; born 22 May 1997) is a Japanese tennis player. He represents Japan in competitions, though he played for Australia from 2010 to 2015, and from 2017 to 2025.
Santillan was born in Tokyo to a Japanese mother and a South African father. He lived the first 8 years of his life in Japan before his family relocated to the Gold Coast, Australia and became citizens. He played much of his junior tennis at the Gold Coast before moving to Brisbane to join the national academy program at the Queensland Tennis Centre.[citation needed]
Junior career
On the junior tour, Santillan has a career-high ITF junior ranking of 7 achieved in September 2015. Santillan's major highlights on the junior tour included a semi-final at the 2015 Australian Open and doubles finals at the 2014 French Open and the 2015 Wimbledon Championships.
In March 2015, Santillan opted to play under the Japanese flag instead due to a fractious relationship with Tennis Australia.[1] He returned to playing under the Australian flag in 2017, before switching back to Japan in 2025.[2][3]
