Yosuke Asaji shot 4-under 67 Thursday to take the first-round lead at the Asian Amateur.
Asaji, 17, of Japan, was the only player to go bogey-free at the 7,068-yard West Course at Kasumigaseki Country Club, an hour northwest of Tokyo.
The winner of the event will receive a spot in the 2011 Masters. The winner and the runner-up will also earn a place in International Final Qualifying for 2011 British Open at Royal St George’s.
Chang-Won Han won the inaugural Asian Amateur last fall.
“I played perfectly today with no bogeys, and I only missed the green on one hole,” Asaji said. “I think I play well at Kasumigaseki, so hopefully I can do better than last year, when I finished 41st, because I really want to play in the Masters in the future.”
Hideki Matsuyama, Australia’s Jake Higginbottom and Koreans Jae-Hyeok Lee and Il-Hwan Park shot 68.
Matsuyama, 18, started on the back nine and made four birdies in a row from Nos. 14-17.
The 72-hole event will end on Sunday.
