The Heartland New Tower (ハトランドニュータワー, Hatorando Nyū Tawā) is an attraction in the Heartland Theme Park.
It is composed of two towers, which are connected by a globe surrounded with stripes. Each tower contains a Dueling stadium - the Red Stadium and the Blue Stadium. According to Luna, the upper part of the building is actually a device which can open the door to another world, causing the annihilation of Heartland City in the process.
After creating a duplicate of Mr. Heartland, Kyoji arranges a double Duel in the tower between the remaining Number Hunters, including himself, using his duplicate of Mr. Heartland to commentate the Duels.
