"The past year has gone by so quickly," Payne said.
"When I think back to the start of the under 17s to where I am right now and everything that's happened it's a dream come true. Having played for the All Whites is every young Kiwi footballer's dream so it's been a big year for me.
"Any chance to represent New Zealand is a proud moment and going to age group World Cups is a pretty cool experience. Playing for the different teams in just over a year something I'll look back on and think how lucky I was at some stages and how cool it's been."
Long-term, Payne said being part of an All Whites team that qualifies for the 2014 FIFA World Cup in Brazil is high on his list of targets, but more immediately he and his Oly Whites teammates are aiming to get out of an Olympic group featuring Belarus, Egypt and Brazil.
Preparations for that mission enter a new phase for Neil Emblen's charges against Japan.
Like Payne, All Whites Cameron Howieson and Michael McGlinchey will make their Olympic team debut against Japan and while the likes of Shane Smeltz, Ryan Nelsen and Kosta Barbarouses will be used to hitting the ground running on international duty, some new combinations will need to be forged with younger New Zealand-based players.
Emblen will be without the services of West Brom striker Chris Wood and Ipswich Town defender Tommy Smith who join the team in Korea for their next warm up match while Marco Rojas arrives in Tokyo on the morning of the match. Tim Myers is suffering from virus while Dakota Lucas is carrying an ankle injury.
The match at the National Stadium in Tokyo kicks off at 10.55pm tonight with coverage on Sky Sport 3 from 10.30pm.
