The National Japan Bowl is a day long academic language competition for high school students studying the Japanese language. Students are tested on grammar, kanji, katakana, kotowaza, culture, current events and listening comprehension. The competition is open to students of Japanese levels II, III, and IV. Those who speak Japanese at home or have had significant exposure to the language outside of the traditional high school curriculum are ineligible. A team is made up of two or three players representing one level of competition. Schools may submit a team for any or all three levels. Only one team per school, per level is permitted.
