South Korea's I.J. Jang ended a seven-year drought on the Japanese tour with his second career victory at The Crowns on Sunday.
Jang, who went into the final round at Nagoya Golf Club two shots off the pace, carded an 8-under 272 to finish two strokes ahead of overnight leaders Steven Conran and Yoshikazu Haku for the ¥24 million win.
Ryo Ishikawa shot a 70, which left him in an eight-way tie for 11th at 2 under.
"I can't think straight; it's my first championship in seven years," said the 39-year-old Jang, who had five birdies against a bogey for a 66 on the day.
"Even though I've had chances to win every year, I'd forgotten what it feels like to actually do it. I'm glad I persevered this whole time," he added.
