Space Mountain is a roller coaster in Tomorrowland at Tokyo Disneyland. While it's not a "must do," it is also recommended. The minimum height to ride is 40 inches.
However, the attraction was given a refurbishment from October 2006-Apirl 2007. The ride reopened with new rockets, new effects, redesigned queue, and much more. The ride still does not have a sound system.
