The All-Japan Corporate Ekiden Championships is a series of races contested between Japan's corporate (business) running teams. The structure involves regional qualifying races and a national championship for women and for men. The All-Japan Men's Corporate Ekiden Championship, also called the New Year Ekiden  takes place in Japan's Gunma Prefecture on 1 January.

Teams for the women's championship gain qualification into the final ekiden race through a series of 3 preliminaries  (2011 summary).
