He wears Uniqlo clothing and as of the beginning of 2017 red Nike, Inc., Nike Vapor Tour shoes after having played for almost a decade in Adidas.

Playing style

With solid and consistent shots on both wings, Nishikori plays most comfortably at the baseline, using dominating groundstrokes to push his opponents around and hit winners. He can generate a lot of pace, especially on his flat backhand, while his Western forehand is accurate and consistent. However, he also has the ability to play defensively and hit consistently to wear out his opponents. Because of this, many people have commented that he has the offensive ability of Fernando González and the defensive skills of Novak Djokovic. Many critics and fellow players have said that Nishikori's two handed backhand is one of the best on the tour, on par with that of Djokovic and Andy Murray, Murray. Under the coaching of Michael Chang, Nishikori has gained the habit of taking balls earlier without compromising consistency, reminiscent of Andre Agassi, allowing him to take time away from his opponents. Nishikori has a slightly unusual style of hitting groundstrokes on both wings, winding up the racket with a short but compact backswing, and hitting the ball right at its peak. These make his groundstrokes powerful, accurate and unpredictable due to the delayed backswing, which prevents opponents from anticipating which direction the ball will go.

He has also been praised for his return of serves, which he executes well due to his ability to take them quickly. He is known to hit winners off return of serves with strong and accurate groundstrokes.

Although his serve is not exceptionally strong, it is consistent enough to prevent opponents from easily winning points off it. He has a flat first serve that can reach speeds of up to 120 mph and employs a topspin second serve.

Nishikori holds one of the highest percentages of deciding set wins in the open era.
