Kapur picked up a cheque of USD 80,000 after finishing with a four-day total of 13-under 271, ending four behind the leader.
He had rounds of 67, 68, 69 and 67 at the USD 1.9 million event sanctioned by the Asian Tour and Japan Golf Tour.
The second top-five finish of the season for Kapur also more than doubled his earnings this year on the Asian Tour. It also brought him up from 22nd to 11th place on the Asian Tour Order of Merit for the year.
"I'm pretty happy. It is nice to string four good rounds together. I've been up there on the leaderboard lately and had something to prove to myself. I wanted to carry the form for four rounds," Kapur said.
"Being on the leaderboard and not finishing the job has been disappointing but this week was nice. I played really nice but unfortunately the putt on the last didn't drop. But this is golf and we accept it. It's nice to be up there and have the juices flowing.
"I was solid. I bogeyed the first and then played really good golf. I gave myself a lot of chances. For the first time this week, I felt comfortable off the tees which is nice. They say better late than never," he added.
Even as Kapur rose from overnight 11th to fourth, his playing partner and Asian Tour rookie Masanori Kobayashi produced a stunning front nine of seven-under 28 enroute to a nine-under 62 and won the title on home soil. MORE
