The J.League awards are represented by a ceremony, which is hosted every year in December, at the end of the season.
Only five players won this award twice: Masashi Nakayama, Ryoichi Maeda, Joshua Kennedy and Yoshito Okubo.
Other four players won both the top-scorer award and the one for Most Valuable Player: Masashi Nakayama in 1998, Naohiro Takahara in 2002, Marquinhos in 2008, Hisato Sato in 2012 and Yu Kobayashi in 2017.
To be considered a rookie, there are some criteria to meet: The youngest-ever winner is Takayuki Morimoto: he won the award in 2004 at the age of 16.
In the past, the award usually went to the manager of the champions, though this has varied somewhat over the years.
