Among them are men's wheelchair singles number one and home favourite Shingo Kunieda of Japan, Dutch women's wheelchair singles number one Diede de Groot and quad singles world number one Dylan Alcott of Australia.

Alcott is the reigning Olympic champion.

Qualification was earned based on the ITF wheelchair tennis rankings as of June 7.

As well as two-time Paralympic singles champion Kunieda, Rio 2016 bronze medallist Yui Kamiji will be carrying Japanese hopes in the women's wheelchair singles.

Britain's Gordon Reid is set to defend his men's wheelchair singles title.

Five-time Grand Slam winner Gustavo Fernández of Argentina and reigning Australian Open champion Joachim Gérard of Belgium will also be among the top contenders in the men's wheelchair singles.

Reid is one of seven Britons set to compete at the Games, with other medal contenders including Alfie Hewett in the men's singles, Jordanne Whiley in the women's singles and Andy Lapthorne in the quad singles.

Jiske Griffioen of The Netherlands won the women's title at Rio 2016 but has since retired, meaning a new champion will be crowned.

Brazil and the United States also have seven players due to compete, while The Netherlands has eight and hosts Japan 10.

American David Wagner will start as a podium favourite in the quad singles, while Dutch player Aniek van Koot has won the women's singles silver medal at consecutive Paralympics.

Entries for the doubles events - men's, women's and mixed wheelchair doubles - are set to be announced at the end of July.

Wheelchair tennis is scheduled to take place at Ariake Tennis Park from August 27 to September 4.
