The agreement will see the company support the tour through 2021 and they will continue to hold the title sponsorship of the Wheelchair Doubles Masters.

UNIQLO will also become an official partner of the BNP Paribas World Team Cup tournament, considered the Davis and Fed Cups of wheelchair tennis.

They will also be the title sponsor of the wheelchair tennis rankings, published on a weekly basis for men, women and quads players.

"It is very gratifying for all of us at the ITF who care passionately about wheelchair tennis to see a brand like UNIQLO not only extend but expand its role in the sport," said David Haggerty, the ITF President.

"Wheelchair tennis is one of the most successful disability sports with growing audiences around the world for these outstanding athletes.

"With UNIQLO’s support and that of the other sponsors of wheelchair tennis, the ITF can continue its work in this important area."

The ITF Wheelchair Tennis Tour began in 1992 with 11 tournaments and has now expanded to over 150 events annually in 40 countries.

UNIQLO, sponsors of the tour since 2014, currently boast Japanese wheelchair tennis star Shingo Kunieda as a global brand ambassador.

"As an athlete, and as a UNIQLO global brand ambassador, I am honoured to take part in the UNIQLO Wheelchair Tennis Tour," said Kunieda, a 20-time Grand Slam singles champion.

"All tour competitors are very grateful to UNIQLO for supporting wheelchair tennis, whose tournaments have grown in stature in the past few years.

"I will continue to do my best to boost the sport's status."
