Sushi is Japan's original fast food, at least in the literal sense. However, most sushi bars are too small and expensive to qualify for the more common meaning of the term "fast food." Kaiten (revolving) sushi, on the other hand, fits the term to a T. The conveyor belt system made sushi more affordable to the hoi polloi back in the '70s by stressing volume over every other consideration.

is the cheapest of the chain kaiten sushi restaurants. They regularly charge only ¥105 for a standard two-piece dish, with some items priced slightly higher. However, until July 16, the price at all 363 stores for everything on the menu is only ¥90 during weekdays, all day. And don't forget, you can get all the tea and gari (ginger) you want for free. They're promoting the deal with a pretty clever TV ad campaign.
