Royal Tokyo is a hotel in Tokyo, Japan; the Simpsons stay here when they go to Japan.
The rooms feature bowing doormen; rice-paper walls, which Homer destroys; high-tech talking toilets that spray fountains of multi-colored water and have a camera in the bowl; and a television, on which Bart finds a channel that happens to be linked to the camera in their toilet, resulting in an unpleasant view for the family when Homer sits on it. The Simpsons' room has views of the Imperial Gardens, the Meiji Shrine, and the Hello Kitty factory.
