Korean Ji-Yai Shin produced a flawless performance to earn a two-stroke lead after the second round at the Mizuno Classic.
Shin shrugged off miserable conditions to card a bogey-free six-under-par 66 on a chilly, occasionally wet day at Kintetsu Kashikojima Country Club.
"Today feels very comfortable," said the British Open champion, who posted a 10-under 134 total with one round left at the co-sanctioned LPGA and Japan LPGA Tour event.
Japan's Mayu Hattori, the first round co-leader, stayed in the hunt with a 69 for second place on eight under, with Korean Jee Young Lee and Japan's Shiho Oyama equal third, three shots behind.
Shin is aiming for her second victory in Japan this year, after winning the PRGR Cup.
The highlight of her round was a tap-in birdie at the par-four 15th, where she struck a six iron to six inches.
