Chandni Canan BauerNasa Hataoka knows how to win the TOTO Japan Classic. She’s done it twice already. What she has never managed, anywhere in her professional career, is to successfully defend a title.
That is the rather significant piece of unfinished business facing the Japanese star this week, and a second-round 64 suggests she has every intention of putting it right.
The defending champion produced eight birdies and an eagle in the lowest round of the day, moving to the top of the leaderboard ahead of compatriot Miyu Yamashita, who is herself enjoying a remarkably productive season.
With two rounds completed, Hataoka leads, Yamashita sits second, and Ana Belac and Fuka Suga share third.
Hataoka Finds Her Form at Just the Right Time
There was plenty to admire about Hataoka’s second-round performance beyond the number on her scorecard.
She found 11 of 14 fairways, hit 16 of 18 greens in regulation and needed just 26 putts. Her 14 birdies across the opening two rounds also put her joint-top of the field in that particular department.
For a player who has already lifted this trophy in 2018 and 2025, the surroundings are familiar. This is her seventh appearance at the tournament, with a tied-eighth finish in 2023 another indication of her comfort at the event.
Her victory last year ended a winless spell stretching beyond three years and delivered the seventh LPGA Tour title of her career.
The 2026 campaign has brought five top-10 finishes from 19 starts, including a share of sixth at the US Women’s Open and another tied-sixth finish at the BMW Ladies Championship in her most recent appearance.
Currently ranked 21st in the Rolex Women’s World Golf Rankings, Hataoka has accumulated 60 career LPGA Tour top-10 finishes and more than $12 million in official prize money.
Those are substantial numbers. Yet the successful title defence remains conspicuously absent.
Yamashita Arrives With Momentum of Her Own
If Hataoka is hoping to break new ground, Miyu Yamashita has already enjoyed that particular pleasure.
The Japanese player successfully defended her Maybank Championship title last week, securing her third LPGA Tour victory of the season. Now she is threatening to add another trophy to an increasingly impressive 2026 campaign.
Yamashita followed her opening round with a five-under-par effort, finding 11 fairways and 16 greens while recording 29 putts.
Perhaps more tellingly, she has made just one bogey through 36 holes.
Her consistency has carried her into second place in a tournament where she finished third last year.
This is Yamashita’s fifth TOTO Japan Classic appearance, having contested three editions as a JLPGA Tour member and two since joining the LPGA Tour.
She also claimed the Sony JLPGA Championship, one of the Japanese tour’s major championships, in her only JLPGA appearance this year.
Having spent four years competing on the domestic circuit before moving to the LPGA Tour, Yamashita is hardly unfamiliar with the demands of golf in Japan.
And having successfully defended a title just days ago, she knows precisely what Hataoka is attempting.
Belac and Suga Keep the Pressure On
Behind the leading pair, Ana Belac and Fuka Suga have ensured the chasing pack remains interesting.
Belac’s presence near the top of the leaderboard is particularly notable given how late she entered the tournament.
The Slovenian secured her place in the field following Ariya Jutanugarn’s withdrawal on Monday and has made the most of the opportunity in her first TOTO Japan Classic appearance.
Eight birdies helped her climb 13 positions into a share of third. She found 11 of 14 fairways and 13 greens in regulation, while requiring only 24 putts.
Suga, meanwhile, has taken a steadier route to the same position.
The Japanese player followed her opening 67 with another 67, completing the second round without a bogey. Like Yamashita, she has dropped just one shot across the opening 36 holes.
Suga finished tied 42nd on her tournament debut last year, but her domestic form suggests she is well capable of improving considerably on that result.
She has already won the Taiwan Foxconn Ladies Golf Tournament on the JLPGA Tour this season and currently occupies fifth place in the JLPGA Mercedes Rankings.
A Familiar Winner Chasing Something New
The TOTO Japan Classic has produced some remarkable scoring over the years.
Annika Sorenstam still holds the tournament’s 36-hole record of 126, set in 2003, alongside the 54-hole mark of 192 from the same edition.
The 72-hole record belongs to Mone Inami, whose 266 in 2023 established the benchmark for the tournament’s expanded format, introduced in 2022.
Hataoka’s latest 64 is one stroke outside the tournament’s 18-hole record of 63, a mark matched ten times, most recently by Hana Wakimoto in 2024.
Records, however, are unlikely to be occupying much of the defending champion’s attention.
She has won this tournament twice, knows what it takes to finish the job and has now put herself in front once again.
The complication is that Yamashita, immediately behind her, has spent the past week demonstrating exactly how to defend a title.
For Hataoka, there would be a certain satisfaction in finally doing the same.
