Only a handful of businesses have managed to actually increase sales during the current economic downturn. Two are no-brainers: fast-food Leviathan McDonald's and cheapo clothing retailer Uniqlo. Less generally known is the fact that the restaurant chain, Gyoza no Osho, has enjoyed 74 consecutive months of sales growth. Revenues for the quarter ending in June were ¥15.5 billion, which is 23 percent more than sales for the same quarter in 2008. Some months have even seen a 100 percent increase in revenues over the previous year.

As the name indicates, Osho's specialty is gyoza (pot sticker), but it's more of a general purpose Chinese food chain than a restaurant that pushes ramen — which is prominent on the menu, but stir fry seems to be more their bag. The first Osho opened in Kyoto in 1967, and now there are 533 outlets nationwide, though almost none in northern Japan, which doesn't seem that interested in Chinese food.
