Hataoka became the first home player in seven years to win the Japan title, firing seven birdies and two bogeys to finish at 14 under par at Seta Golf Club in Shiga.

“I’m glad to win here in Japan,” Hataoka said before a big crowd adding that she had faced “a challenge” after back-to-back bogeys at the 11th and 12th.

The diminutive 19-year-old, who is just 1.58 metres tall, sank further birdies at the par-four 14th and par-five 18th to seal the victory.

“I was able to play calmly from the 13th hole,” a smiling Hataoka said as she kissed the winner’s trophy.

In June, Hataoka became the 14th Japanese player to win an LPGA title by finishing 54 holes at Pinnacle Country Club in Rogers, Arkansas, on 21-under par 192, the lowest score in tournament history.

Local favourite Momoko Ueda, who won the tournament in 2011, shot five birdies with a bogey for a 68 to share second place with Japan’s Saki Nagamine and Spain’s Carlota Ciganda.

China’s Feng Shanshan, the two-time defending champion, shot 72 to be tied for 30th, and newly-crowned world number one Ariya Jutanugarn tied for 19th after carding a 69.
