The 54-year-old Scot two-putted for par from 50 feet on the par-4 18th, hitting his first to one-and-a-half feet, for a 5-under 67 and a one-stroke victory over Billy Mayfair and second-round leader Scott McCarron.
“The greens were as good as any, and I mean this, as good as any as we have ever putted on, ever,” Montgomerie said. “And we’ve putted on some great, great surfaces. In the 30 years as a pro, these are as good as any we have putted on as a putting surface. Superb putting surfaces.
“And the way the course was manicured was exceptional.”
Montgomerie finished at 14-under 202 for his fifth victory on the 50-and-over tour and first in nearly a year. He won 31 times on the European Tour and topped the tour’s money list a record eight times – seven in a row from 1993-99 and the last in 2005.
“It’s a big deal, a very big deal,” Montgomerie said about the tour’s first visit to Japan. “And let’s hope that the success of this event goes forward and not only allows the PGA Tour Champions to come back and compete but also allows the PGA Tour to come and play here. It will be fantastic if that time ever comes.”
Montgomerie ran in a 60-footer on the par-4 13th in the middle of a three-hole birdie spree, and made two key six-foot putts – the first for par on the par-3 16th and the second for birdie on the par-5 17th to break a tie for the lead with Mayfair.
“I think when I holed the putt on the 14th hole for my third birdie in a row, I felt that I had a chance then,” said Montgomerie.
“I’m a big scoreboard watcher and knew I was leading. I just had to make sure I birdied 17 and par in, which I did.”
Mayfair, playing two groups ahead of Montgomerie, settled for a 66 after missing a six-foot birdie attempt on 18.
McCarron, who had won three of the previous six events, birdied the final two holes for a 71. He opened with a double bogey.
Montgomerie birdied four of the first five holes on the back nine – also holing putts of 20 feet on the tenth, 15 feet on the 12th, and 14 feet on the 14th – after playing the first nine in even par with a bogey and a birdie.
“It wasn’t easy,” Montgomerie said. “The wind was swirling in the trees, the pins were located in some very difficult positions, very difficult, right on the edges of the greens on slopes.”
Sidelined for two-and-a-half months in the spring by torn ligaments in his left ankle, Montgomerie won for the first time since beating McCarron late last September in a play-off in Canada in the Pacific Links Bear Mountain Championship – a title he will try to defend this coming week in Victoria, British Columbia.
The Hall of Famer’s first three Champions victories came in majors – the 2014 and 2015 Senior PGA Championship and 2014 US Senior Open.
“I’m just beginning to play the way that I have the last three years,” Montgomerie said.
