The 2005 J.League Division 2 season was the 34th season of the second-tier club football in Japan and the 7th season since the establishment of J2 League.
In this season, two additional clubs joined from the third-tier Japan Football League, though the number of participating clubs stayed at twelve, as no teams were relegated from 2004 J1 League to replace the two promoted clubs. The clubs competed in the quadruple round-robin format for the top two promotion slots. The third placed-finisher participated in the Pro/Rele Series for the promotion. There was no relegation to the third-tier Japan Football League.
