     In most places children are banned from working. But at a theme park in Japan, boys and girls can

fight fires, catch thieves and also perform the more boring tasks of making hamburgers and delivering

parcels.

     Kidzania, in a shopping centre in Tokyo, is like a real town where children can act out their dreams

of future careers. The streets are lined with shops and even a bank. Everything inside is two-thirds normal

size to accommodate (容纳) the young workers. After their parents buy the ticket, children can try

several jobs.

     Being a firefighter is a dream of many children. Children are being trained in the fire station of the town. Suddenly an alarm bell rings and they put on firefighter clothes before running towards the scene. The

scene is created with lighting and fake smoke, but for children it is real enough. "Sometimes it's too hard

for them," says the worker Ryoko Ishikura. "Some kids are in tears when they hear the alarm and the

fire breaks out. But even with tears in their eyes they go on running and fight the fire bravely." 

     The idea for Kidzania started in Mexico. It arrived in Japan three years ago and there are also parks in Chile, Indonesia and Portugal. Another one is opening soon in Dubai.

     The children are rewarded for their efforts in "Kidzos", the theme park money. In most countries it is

quickly spent in shops and restaurants. But in Japan, children form long queues at the theme park's bank. "I'll keep it in the bank," said nine-year-old Noa Morita, who wants to be a fashion designer.
