The founder of the Genroku-zushi Restaurant, Shiraishi Yoshiaki, came up with the idea of serving sushi on a conveyor belt. After four years of trial and error, the first conveyor-belt sushi bar opened in 1958. It was called Genroku-zushi. Within a few years, Shiraishi had a chain of 240 outlets all over Japan. At this type of restaurant, the bill is calculated after the customers say how much they have eaten.
People say Osaka merchants look after the interests of their customers.
This Osaka entrepreneur is no exception. His idea added modern technology to a traditional Japanese meal, and spread it to different parts of the world.
