The Squirrels' average home crowd figure in 2007 continued the more or less year-on-year increase since the club joined the J-League in 1999. An average 11,741 falls just shy of the 12,000 target, but can be regarded as a success when considering what a difficult year it has been on the pitch, with poor performances, disappointing results and an even less potent strike force than had previously been the case under ex-coach Toshiya Miura.
The number represents a rise of 1507 on the 2006 equivalent, putting Omiya Ardija above only relegation-threatened Sanfrecce Hiroshima in the J1 ranking. Indeed, both Vegalta Sendai and Consadole Sapporo in J2 both have superior average gates as well. However, discounting the promoted sides Vissel Kobe, Yokohama FC and Kashiwa Reysol - all of whom reported large increases in their levels of support - the Squirrels' is the fourth-biggest rise in J1, behind only Kawasaki Frontale, Shimizu S-Pulse and Ventforet Kofu.
