Since the park opened in 1983, Tokyo Disney Resort has regularly been one of the most profitable Disney resorts. By 1994, over 149 million people had entered through the gates of Tokyo Disneyland, more than Japan's entire population of 127.6 million at the time. In 1996, it employed 12,390 people, making Tokyo Disneyland the biggest workplace in Japan's diversionary outings at that time. Many speculate that Tokyo Disneyland is such an economic success due to timing.
