With mad cow disease and the bird flu still making some people anxious about the safety of beef and poultry, an increasing number of Tokyo residents are turning to mutton and lamb.

The number of restaurants serving lamb has grown since last year, said Fumiaki Shimono, 43, operator of Tokyo Jingisukan (mutton barbecue) Club, a Web site he created five years ago for lovers of lamb.

His Web site says there are now 40 restaurants specializing in lamb and mutton meals in Tokyo, up from four in 2000.
