Even though it is the Oriental Land Company that owns and operates the resort, the park was designed and built by Walt Disney Imagineering. The park was modelled on the Magic Kingdom in Florida and Disneyland in California. Cinderella's Castle is almost an exact replica of the Castle at Walt Disney World in every way apart from a slightly different colouring nowadays.
According to The Themed Entertainment Association's findings, Tokyo Disneyland remained the 3rd most visited theme park (of all theme parks, not just of the Walt Disney Company) worldwide in 2008, with 14,293,000 visitors (in comparison, Magic Kingdom had 17,063,000, Disneyland had 14,721,000 and Disneyland Paris had 12,688,000).
So, shall we pick up a map and have a good look at the park, just to get used to it?
And what about a map of Tokyo Disneyland itself?
