     Sony and Toyota are struggling. But one brand name is booming (繁荣) in Japan during the economic

slowdown-Mickey Mouse.

     According to the company that runs Tokyo Disneyland, Japan's busiest theme park will be more packed

than ever over Christmas and New Year's Day. Despite the bad economy, it's already been a record year for

an escape which is cheaper than the average night out in pricey Tokyo.

     "Here, economic depression (萧条) seems a world away " visitor Namie Katsunuma said. "This is the only

place where I can totally forget the economic worries and hardship of my life."

     The single mother's salary at an auto factory was cut in November, but with her $ 500 yearly pass in hand,

she makes the 95-km journey from her home to Tokyo Disneyland every couple of months.

     The park's operator, Oriental Land Co., estimates (估算) a record 26.5 million people will visit Tokyo

Disneyland and its nearby sister park, Disney Sea, during the financial year ending in March. The company is

forecasting sales of a record $ 4.2 billion, up almost 10 percent.

     "In a way, the economy works well for Tokyo Disneyland," said Hiroshi Watanabe, an economist at the

Tokyo-based Daiwa Research Institute. "Because of the economic depression, people have stopped buying cars

and houses or going to Hawaii, and Tokyo Disneyland offers an affordable and pleasant alternative."

     Around the world, Disney's theme parks have been a bright spot for the brand this year as people seem to

look for an escape from bad times.
