In 2017, Hataoka played on both the LPGA Tour and LPGA of Japan Tour. On the LPGA Tour, she made 9 cuts in 17 events and finished 140th on the money list, losing her card. On the LPGA of Japan Tour, she won two events, including a second Japan Women's Open, and finished 14th on the money list. She again competed in the LPGA Final Qualifying Tournament, finishing first to re-earn her LPGA Tour card for 2018.[5]
On 31 March 2019, Hataoka won the Kia Classic at Aviara, closing with a 5-under-par 67 to clinch a three-stroke victory.[11]
2021
In June 2021, Hataoka started the final round of the U.S. Women's Open in sixth place. She shot a final round 67 at The Olympic Club and got into a playoff with Yuka Saso. Saso won with a birdie on the third playoff hole.[12]
Hataoka won her fourth LPGA Tour title, the Marathon Classic by six strokes, after 54 holes, because poor weather conditions made the course unplayable on Sunday, 11 July.[13]
Hataoka won her fifth LPGA title, and the second time (2018) in the Walmart NW Arkansas Championship, at Rogers, Arkansas on 26 September, by a stroke, after 54 holes. Minjee Lee and Ji Eun-hee were tied for second place. She set the scoring record in the 2018 event. She is ranked third for a Japanese golfer in wins.[14] With her $345,000 win, she rose to second place in the money ranking, trailing only number 1 world-ranked Nelly Korda.[15]
2022
In 2022, she won the DIO Implant LA Open on 24 April, her sixth win on the LPGA Tour, and the $225,000 prize. Her world ranking jumped six places, from 12 to 6,[16] which is where she ranked at the end of 2021.[17] She had missed the cut in her previous tournament the week before at the Lotte Championship, but won by five strokes over Hannah Green. She had a six-stroke lead after the 17th hole with a chance to tie the tournament record at 268, but bogeying the 18th made it a 269.[1] With a four-stroke lead going into the final round, her new ball position and swing change that weekend from a new coach, helped her miss only four fairways and seven greens.[18]
