American Football was first introduced to Japan in the 1930s, although it was not until after WWII, that it was played competitvely, with the Rice Bowl, Japan’s version of the Super Bowl, being played between the Universities since 1947, and since 1984 between the University Champions and the Social Champions (Business League – currently X-League).
There is also a third League in Japan, which is the Private Club League, opening up American Football to non-students and non-Corporate Workers. The JPFF (Japan Private Football Association) organises the Ocean Bowl between the JPFF East and JPFF West Champions.
