KidZania, the theme park where children can role-play professions such as doctor or firefighter, has proved popular around the world: entertainment centers are now operating in 10 countries in addition to Japan, including Mexico, Indonesia and Portugal.

Similarly, in Tokyo, there is a business that offers adults the chance to try their hand at interesting jobs, getting guidance directly from professionals in the field, in the name of travel.

"We think each job is its own world. Based on that thought, we provide customers 'travel' opportunities to the various worlds," said Tsubasa Tanaka, head of Job-travel Agency.
