"We have to start looking at 2020," she said at Wimbledon when asked about her successful doubles tenure with sister Serena. "That would be impressive. If you think this year's impressive, hold on.
"That would be a blessing if we did play. I'm so grateful for each and every time we've had a chance to play and qualify. It's been beyond our dreams. It means the world to us to play together."
Venus and Serena have been the story of Olympic tennis since the two first paired up to win gold in women's doubles back in 2000. Since then, the sisters have each amassed quite a haul, each taking gold in singles - Venus in 2000, Serena in 2012 - and earning three golds in women's doubles in 2000, 2008, and 2012.
She narrowly missed out on a fifth gold medal in mixed doubles, winning silver alongside Rajeev Ram in Rio.
"Tokyo is about if I want to be there," the five-time Wimbledon winner said in August. "If I want to continue to work as hard. It's a lot of hard work. I have to want to do the work. So we'll see."
Her resolve appears to have solidified even more in the off-season, discussing the possibility of playing through 2020 on a soon-to-be broadcast program on the Hallmark Channel.
"I am targeting that to see if it's possible to play there. While you're out there playing, I love that challenge, I love the pressure, it's all a privilege.
"If I can be out there, I will be."
