The Japanese National Duel Monsters Championship, known as the Duel Monsters Tournament in the manga, was a Duel Monsters tournament in the Yu-Gi-Oh! manga and anime to determine the Japanese champion. In the dub, it was referred to as a Regional Duel Monsters Championship, suggesting it only encompassed a region, rather than the whole country. In the manga and Japanese anime, the regionals are mentioned as being a lower stage than this tournament.
