As in the United States, convenience stores in Japan provided customers with a variety of products carried by general retailers as well as food retailers. In Japan, the convenience store sector was one of the few business areas that continued to grow during the prolonged 1990s downturn. From 1991 to 2002 the number of convenience stores in Japan increased from 19,603 to almost 42,000. As a percentage of all retail stores in Japan, this represented an increase from 1.2 percent to 3.2 percent. During that period, annual sales at convenience stores more than doubled from just over 3 trillion to 6.7 trillion yen. As a percentage of all retail sales in Japan, this represented an increase from 2.2 percent to 5.0 percent.
