The Japan Championship Rice Bowl is an annual American football national championship game held in Japan every January 3 that determines the champion of the X-League. The game was originally a collegiate all-star game until 1983. From 1984 to 2021, the game matched the champions of the Japan X Bowl with the college Koshien Bowl winners. However, after lopsided victories to the professional teams, discussions took place over whether this was a reasonable contest, and from 2022 the contest was changed so that it was between the two top professional teams. The game can draw over 30,000 spectators.
The current 2026 champions are the Panasonic Impulse. This is the first time the Impulse has won back-to-back Rice Bowl titles.
