Led the Japan Golf Tour order of merit, on the strength of three victories.

Won for the second time of his campaign, at the Coca-Cola Tokai Classic in Japan. Despite a final-round 73, that saw him make four bogeys against and eagle and a birdie, he held off Tadahiro Takayama by a stroke. Was tied for seventh after the opening round but took the lead at the halfway point and led the rest of the way.

Final victory of the season came at the Japan Open, where he defeated Kenichi Kuboya in a playoff.

Also had a pair of runner-up finishes to his credit on the Japan Golf Tour. Was T2 at the Japan PGA Championship, losing by two strokes to Hiroo Kawai. Two weeks later, shot four rounds in the 60s (68-68-68-65) and finished second at the Tsuruya Open.

A week after playing in the U.S. Open at Congressional CC, where he T42, he returned to the Japan Golf Tour and T3 with Ishikawa, three strokes behind winner Jung-Gon Hwang at the Gateway to the Open Mizuno Open. 2010: Had a strong season, winning the SK Telecom Open on the Asian Tour for a second time in his career, three years after his first title there. Shot four rounds in the 60s to win by three strokes. Also had a T7 at the Kolon 53rd Korea Open.

On the Japan Golf Tour, he didn't win but had six top-10s and eight top-25s in 11 starts, missing only one cut. His top performance was a fifth-place showing at the Sun Chlorella Classic. 2009: Missed the cut in his only two career PGA TOUR starts—the Sony Open in Hawaii and the U.S. Open.
