Momoko Ueda shot 4-under 68 on Saturday to maintain a one-shot lead entering the final round of the Toto Japan Classic in Shiga.
A two-time winner of the tournament, Ueda stands at 14-under through three rounds at the Seta Golf Club. One shot back is Scotland's Gemma Dryburgh at minus-13 after posting a 65, mixing eight birdies with a bogey.
Despite being in position for a wire-to-wire victory, Ueda was slightly disappointed with her Saturday round.
