Wheelchair tennis players Yui Kamiji and Shingo Kunieda on Friday became the first two Japanese athletes to qualify for the 2020 Tokyo Games by winning gold at the Asian Para Games in Indonesia.

Kamiji defeated China's Zhu Zhenzhen 6-3, 6-4 in the women's singles gold medal match at the ongoing Asian Para Games in Jakarta.

Kunieda later beat compatriot Takashi Sanada 6-2, 6-3 in the men's final.

The winners of the singles tournaments at the eight-day games automatically qualify for the 2020 competition.

With her victory, the 24-year-old Kamiji became the first Japanese to qualify for either the Olympics or Paralympics to be held in Tokyo.

She is set to compete in her third straight Summer Games following London in 2012 and Rio de Janeiro in 2016. She won bronze in women's singles at the Rio Paralympics.

The 34-year-old Kunieda, who has amassed 22 career Grand Slams, will be looking to add a third Olympic gold following victories in London and at the 2008 Beijing Games.
