The Haunted Mansion was an opening day attraction at Tokyo Disneyland, where it is part of Fantasyland. The Tokyo Disneyland version is largely a duplicate of the Magic Kingdom version, although it did not receive the changes made in the 2007 refurbishment of the Magic Kingdom version.
This ominous gothic mansion is haunted by 999 ghosts, goblins, and ghouls. They're all "dying" to make their number an even 1,000. Look over there! It's a statue with glowing eyes. And invisible hands are playing strange music on that piano. Now, who's that sitting next to you?
