Miyuu Yamashita set the Japan LPGA Tour's record for the lowest 18-hole score with a 12-under 60 in the first round of the Miyagi TV Cup Dunlop Ladies Open on Friday.
The 21-year-old Yamashita, who has topped this year's money list, built a five-shot lead over Fumika Kawagishi after racking up 12 birdies without a bogey at Rifu Golf Club in Rifu, Miyagi Prefecture.
She had six birdies on each of the front and back nine.
The previous record, an 11-under 61, had been set by South Korea's Kim Hyo Joo in 2012 and equaled by Mone Inami in 2021.
Yamashita has won twice this year and three times in her tour career. One of her 2022 victories came at a major tournament, the World Ladies Championship Salonpas Cup in May.
