The former world number one and four-time major winner has been named in the Japan squad to face Kazakhstan in Tokyo.
It will be her first appearance in the team competition since February 2020 which means that she hasn't fulfilled the obligation of making it to two ties in one Olympic cycle.
If she is to secure a spot in the Japan team for the Paris Olympics "she'll need to go through the appeals process," a spokesman for the International Tennis Federation (ITF) told AFP.
However, the ITF also reserves a place in each singles draw at the Games to a Grand Slam title winner.
Osaka was absent from the tour from September 2022 until January this year after giving birth to her first child.
At the Australian Open, she was ranked a lowly 831 but a quarter-final run in Qatar followed by back-to-back third round spots at Indian Wells and Miami have lifted her to just inside the top 200 and number four in Japan.
The singles event at the Olympics is limited to 64 players with a maximum of four from each nation.
Osaka has already experienced the Olympics, lighting the cauldron at the opening ceremony of the Covid-delayed Tokyo Games in 2021 where she went on to make the third round.
That appearance came just months after she withdrew from the French Open at Roland Garros - the venue for this summer's Olympics tennis event - citing mental health issues.
Japan's tie with Kazakhstan on Friday and Saturday will be staged at Tokyo's Ariake Coliseum, the venue for the 2021 Olympic tournament.
"She said that she wants to play, so I'm really happy," local media quoted Japan captain Ai Sugiyama as saying when the team for this weekend was announced.
