Tower of Terror drops riders in an elevator inside Hotel Hightower, with a story unique to Tokyo DisneySea rather than the Twilight Zone theme used at other Disney parks. Explorer Harrison Hightower III vanished on New Year's Eve 1899 after mocking a cursed idol, and the hotel stood closed and condemned for more than a decade. The attraction opened in September 2006 in the American Waterfront, with a ride system built by Mitsubishi Heavy Industries.
