From 1947 through 1982 the Rice Bowl, played at the beginning of January, was a game between two all-star teams from the east and the west of Japan. Since the 1983 season the Rice Bowl is the site of the japanese national championship game between the champion of the X League (company teams and club teams sponsored by companies) and the college champion. The champion of the X League (in the Japan X Bowl) and the college champion (Koshien Bowl) are determined a couple of weeks earlier in December.
