A ninja takes you through a dark narrow path, serves you food and drink and performs magic in a restaurant in Tokyo's Akasaka district where the likes of former Prime Minister Junichiro Koizumi and famed film director Steven Spielberg have dined.

The Ninja Akasaka theme restaurant, opened in 2001, has been attracting around 3,000 to 5,000 customers a month, according to Will Planning Inc., its managing company.

Ninja Akasaka "is like a fusion of Disneyland and ninja. When customers come out from the path (that takes them from the entrance to their seats), their faces are beaming with excitement," said Isao Kuramochi, the restaurant's manager.
