A huge prepared-foods section displays ready-made sushi, crab cakes and dishes like beef with curry sauce, that, to be honest, looked better than they tasted in a recent sampling. Customers can also take advantage of the digital photo enlarging services. Sato says the store targets people between 21 and 44 whose household incomes top $80,000.

The Japanese face tough hurdles in the crowded U.S. market. But they believe their edge lies in their mastery of information technology, which, at least at first, will be used mainly behind the scenes for managing inventory and tracking customer preferences.
