'The biggest change is that my core feels stable. I can keep my center of gravity low, which has improved my first step. I want to keep wearing it even after I retire.'

Profile

Born in 1978 in Chiba Prefecture, Matsui is a living legend in the Japanese tennis world who continues to compete globally at age 48. He has a unique background, moving to Canada alone at 16, attending college in Hawaii, and then turning professional. He is a right-handed player known for an aggressive one-handed backhand style.

While he was active in singles, he is especially known as a doubles specialist and has won six All Japan Championships.

In May 2024, at age 46, he achieved a career-high world ranking of 121st in doubles. His ability to keep evolving as he ages has earned him great respect from younger players and fans.

This year, overcoming a right elbow injury from 2025, he has returned with the theme 'One More Roar.' Armed with vitality and strategy, he continues to challenge himself as an active ATP ranker, focusing on doubles at Challenger and ITF tournaments worldwide.
