Ninja Hideout is a stage from Dead or Alive 4.
A building of traditional Japanese architecture set in a Ninja-esque theme; the fight starts in the hallways. The hallways are very small, making the fight's resulting relocation into the mansion's two rooms almost inevitable. There is a door where you can hit your opponent to get them to the other side and into the balcony. From there you can hit your opponent into the balcony and the fight will continue in the courtyard.
The doors automatically open and shut behind the characters. If one character is dominant, he could continue pummeling his opponent, eventually kicking him out of the mansion. But a fight between more balanced fighters will be an intense back and forth between two rooms of the mansion. It's as intense to watch as it is to play.
