The Christmas Bowl (クリスマスボウル, Kurisumasu Bōru) is the annual Japanese high-school American football championship game.
Surprisingly, the competition has been going on for almost as long as the Super Bowl, being only four contests behind.
The Christmas Bowl in the manga and anime series Eyeshield 21 is based on this competition.
The Tokai area is composed only of high schools in Aichi.
The second place teams from Kyoto and Shiga play in a playoff match, the winner of which can participate in the Kansai tournament.
