Michelle Wie fired a one-over-par 73 to trail leaders Toshimitsu Izawa and Yoshiaki Kimura by five strokes after the first round of Casio World Open.
The US teenager, only the second woman to play in a Japanese men's event, teed off from the 10th hole and bogeyed the 16th hole and the second and third.
But she recovered to shoot back-to-back birdies on the sixth and seventh.
The 16-year-old has already played in five men's tournaments but has failed to make the cut in any of them.
However, Wie said her play over the final holes in Thursday's opening round had boosted her confidence.
"Coming back like that will give me confidence for Friday," she said.
"It's good to know I can do that even when I'm not playing that well."
Swede Sophie Gustafson - the only other woman to tackle the tournament - missed the cut in 2003.
