(REUTERS) - Feng Shanshan won back-to-back tournaments for the first time in her career, after the world No. 8 survived a late scare to secure a one-stroke victory over South Korea's Jang Ha Na at the co-sanctioned Japan Classic on Sunday.

The Chinese golfer completed her third and final round with a two-under 70 at the Taiheiyo Club's tree-lined Minori Course to claim her sixth LPGA Tour title, one week after winning the Sime Darby LPGA Malaysia in Kuala Lumpur.

"I haven't won at the LPGA for two years and I just won back-to-back that means Shanshan is back," Feng told reporters.

Feng continued her bogey-free golf from the previous day by mixing four birdies with 13 pars over 17 holes but it was not all plain sailing for the 27-year-old, as she three-putted for double-bogey on the par-four 18th to finish at 13-under 203.

Jang, who beat Feng by a stroke to win in Taiwan last month, shot her third straight 68 but the Korean was always too far back to mount a serious challenge in the final event on the American-based circuit's Asian swing.

Defending champion Ahn Sun Ju tied for third at 10-under alongside Japan's Kotone Hori and fellow South Koreans Ryu So Yeon and Kang Soo Yun.

The US$1.5 million (S$2.1 million) event is co-sanctioned by the LPGA of Japan Tour.
