The Duel Gate (決闘門（デュエル・ゲート）, Dyueru Gēto) is a location in the Yu-Gi-Oh! 5D's manga. It is an entrance on Saiko Island, and is both the starting line and goal for the D1 Grand Prix's final stage. It can only be opened if the participant acquires Star Ticket(s) which have a value of 12 or above; when he does so, by placing the Star Tickets in his Duel Disk, the small door inside the big gate will open, letting the participant enter. The Aerial Fortress Seibal is located beyond this gate.
