Under the agreement, Nishikori will be suiting up in UNIQLO wear for the first time as he takes the court at the Aircel Chennai Open, running from January 3 to 9 in India.

Nishikori, currently one of the youngest players ranked in the top 100 of the ATP World Rankings, has his sights firmly set on becoming the highest ranked Japanese tennis player in history. He is the highest profile athlete to be endorsed by UNIQLO.

UNIQLO will announce more details about the new agreement during a press conference to be held in Tokyo, Japan after Nishikori competes in the Australian Open starting January 11, 2011.
