Marucho's House is a tall skyscraper located in Dan's town. It was constructed during the beginning of Bakugan Battle Brawlers. Though it may seem small on the outside, but it's actually a huge mansion-like tower with many rooms.
- Marucho's room
- Marucho's parent's room (never seen, but implied since they live there)
- Living Room
- Dining Room
- Bakugan Interspace
- Airship storage
- Basement/Bakugan Interspace
- Art Room

- Wave pool in which Kato is seen in
- Closet (entrance)
- Bowling Alley
- A running gag in the series is newcomers' reactions to the bathroom, which is so large and well-decorated that it is often mistaken for a glamorous room. Dan thought it was Marucho's room, Julie thought it was her room when she was staying over, Mira thought it was a ballroom, and Shadow hoped the Brawlers and the Battle Gear data were there.
- The front door leads to a giant closet.
