The Uzbekistan skipper won the honour for the second time after helping his nation claim fourth spot at the 2011 Asian Cup, beating out Honda and Kagawa among others
The 29-year-old midfielder clinched the honour ahead of Iran's Hadi Aghily at Wednesday evening's ceremony in Kuala Lumpur.
Djeparov, who won the award in 2008, played a key role in helping Uzbekistan to their best ever Asian Cup finish, placing fourth at the 2011 tournament in Qatar.
"I'm very happy to have won this award for the second time after winning it three years ago in 2008," Djeparov said.
"I believe every player has this dream to win this award and I believe this is not the end for me as there will be more in the future.
"This second time round, I'm even happier than last time. I hope this award is good for my career now with Al Shabab.
"Football is the same everywhere, It depends on the player how to play from one country to another. Every player should play professionally every time regardless in which country he plays."
Nominees Keisuke Honda, Shinji Kagawa, Koo Ja-Cheol and Yeom Ki-Hun were unable to attend the evening and were subsequently ineligible.
