Naomi Osaka loses to Mia Pohankova in Tokyo

Naomi Osaka lost 6-3, 7-5 to 18-year-old wild card Mia Pohankova in the Pan Pacific Open round of 16 on Thursday, ending her run in front of her home crowd in Tokyo. According to ESPN, the Slovakian teenager will face Alycia Parks in the quarterfinals after eliminating the No. 7 seed.

For Pohankova, who turned 18 only last week, beating a four-time major champion looks like a significant breakthrough. It doesn't tell us how her next match will go. Beating Osaka and beating Parks are separate challenges.

Naomi Osaka loses to Mia Pohankova: the result

Pohankova beat Osaka in straight sets to reach the last eight of the WTA 500-level event.

Here are the key details:

• Result: Pohankova defeated Osaka 6-3, 7-5.
• Round: Pan Pacific Open round of 16 in Tokyo.
• Pohankova’s entry: Wild card; she turned 18 last week.
• Previous achievement: 2025 Wimbledon junior singles champion.
• Next opponent: Alycia Parks in the quarterfinals.

The score establishes what Pohankova achieved, but it doesn't explain how she did it. The available reporting doesn't include a serve-and-return breakdown for this match, so there is no basis for attributing the win to particular tactics or passages of play.

Why Osaka’s first-round form matters

The defeat followed an encouraging start for Osaka. ESPN reported that she beat Jasmine Paolini 6-3, 7-6 (4) on Tuesday, recording seven aces to Paolini’s one in a match lasting one hour and 37 minutes.

That result avenged Osaka’s defeat to Paolini at the previous year’s Miami Open, their only earlier meeting. ESPN also described the 29-year-old as playing some of her best tennis since returning after the birth of her daughter, Shai, three years ago.

In our view, that opening win makes Pohankova’s result more notable. Osaka had beaten Paolini before facing the teenager, rather than arriving without a win in Tokyo.

Osaka’s tournament included both a first-round victory and a second-round defeat. Neither result should erase the other from the assessment.

What makes Pohankova’s breakthrough significant?

Pohankova’s Wimbledon junior singles title provides useful context. She arrived in Tokyo with a notable junior achievement, although a junior title and a senior win over Osaka are different tests.

We see Thursday’s result as an important step: Pohankova beat a four-time major winner in front of that opponent’s home crowd.

Still, the Wimbledon title isn't a complete explanation for the Tokyo win. Nor is Osaka’s major count a shortcut to predicting Pohankova’s next result. Those facts help explain why this victory deserves attention, not why another must follow.

Pohankova deserves credit for reaching the quarterfinals. Assessing what comes next requires a closer look at Parks, not just another look at the Osaka score.

Pohankova vs Alycia Parks: what to watch

Pohankova will face Alycia Parks in the quarterfinals, ESPN confirms. The Osaka result doesn't settle that match in advance.

We would watch Pohankova’s serving and returning against Parks to see how she follows up this win. Those are areas to assess, not strengths established by the available account of her match against Osaka.

Parks needs her own assessment, too. The available reporting confirms the matchup but doesn't provide her recent results, a head-to-head record or a detailed account of her route through Tokyo. There is no reason to fill those gaps with assumptions.

For us, the question is whether Pohankova can build on this result against a different opponent. One upset is worth celebrating without making it a prediction.

Who else is still in the Tokyo draw?

Osaka’s exit wasn't the only significant development on Thursday. According to ESPN, top-ranked Elena Rybakina secured the year-end No. 1 ranking by defeating Yulia Putintseva 6-2, 6-3, while Leylah Fernandez beat No. 14 Elise Mertens 6-2, 7-6 (8).

ESPN also reported that second-seeded Maja Chwalinska and No. 4 Belinda Bencic had withdrawn earlier through injury. Chwalinska had a left-thigh injury, while Bencic had a right-ankle injury.

Those withdrawals don't, by themselves, establish an easier route for Pohankova. Her next opponent is Parks, and that matchup deserves attention on its own terms.
