American Brittany Lang shot a 6-under 66 on Friday to take a one-stroke lead over Japan's Nobuko Kizawa and South Korea's Hee Young Park after the first round of the Mizuno Classic.

Lang, who is winless in four seasons on the LPGA Tour, reached 7-under at Kintetsu Kashikojima with an eagle on the par-5 seventh, but bogeyed the eighth and finished the round with a par.

Vicky Hurst, 2007 winner Momoko Ueda, Bo Bae Song and Mi-Jeong Jeon opened with 68s, and defending champion Jiyai Shin and Japanese star Ai Miyazato topped a group at 69.

Australian Karrie Webb was four shots of the pace with a 70 while top-ranked Lorena Ochoa had a 71 in the event co-sanctioned by the Japan LPGA.
