Yeah, the Oriental Land Company is a publicly traded, for-profit business. Tokyo Disney Resort is also their primary venture. Crowds and culture definitely play a part, but the cheaper parks in Japan have pretty much always been more profitable than the American parks. They're continued proof that "quality will out" and that Disney today is leave huge sums on the table because people who don't like theme parks are making the decisions and being cheap.
Your second sentence explains the difference between OLC and The Walt Disney Company (TWDC).
As their primary source of business, OLC's management team is focused on the amusement park business, often with decades of experience built from the ground-up. They understand the business.
Unfortunately, TWDC's Parks & Resorts leadership comes from the "any good manager can manage anything" school of business.
Current Parks & Resorts Chairman, Tom Staggs, was an investment banker at Morgan Stanley before joining Disney.
Jay Rasulo, Chairman before him, came from Chase Manhattan and Marriot.
Paul Pressler came from a toy company and was well-known to be a 'numbers guy'. His post-Disney crash-and-burn performance at The Gap is well documented.
Along with CEO Bob Iger (from ABC), these corporate leaders look at Parks & Resorts from a financial perspective.
All organizations need a steady financial hand.
However, they also need creative leadership at the helm with a strong feel for the core business.
Parks & Resorts has suffered in the last dozen years exactly because none of these folks, or most of the people who report to them, have a good feel for their theme park product.
