Toryumon is the name of several professional wrestling promotions that have operated in Japan and Mexico. The promotions were owned and operated by Yoshihiro Asai, who is best known under the ring name Último Dragón. Toryumon is a coined word that means Fighting Dragon Gate. The word was derived from the homonym Tōryūmon (登龍門) that literally means climbing up the dragon gate. The Toryumon Mexico promotion was originally created to give graduates of the Último Dragón Gym a promotion to gain their initial in-ring experience in. Its Japan-based sister promotion Toryumon Japan developed a major cult following and grew into becoming one of the hottest independent promotions in the country. The promotion would run for five years. On July 4, 2004, Último Dragón left the promotion and took the name and trademarks with him. Toryumon Japan's wrestlers and officials decided to form a new promotion, adopting the name Dragon Gate and continuing in the traditions of Toryumon. Since then Último Dragón would continue to promote Toryumon events mainly in Mexico but also has occasionally held shows in Japan until 2020 when he signed with Dragongate.
