Sushi
Conveyor belt sushi

In 1958, Yoshiaki Shiraishi opened the first conveyor belt sushi restaurant (回転寿司, kaiten-zushi) named " Genroku Zushi" in Higashi-Osaka. In conveyor belt sushi restaurants, conveyor belts installed along tables and counters in the restaurant transport plates of sushi to customers. Generally, the bill is based on the number of plates, with different colored plates representing the price of the sushi.

When Genroku Sushi opened a restaurant at the Japan World Exposition, Osaka, 1970, it won an award at the expo, and conveyor belt sushi restaurants became known throughout Japan. In 1973, an automatic tea dispenser was developed, which is now used in conveyor belt sushi restaurants today. When the patent for conveyor belt sushi restaurants expired, a chain of conveyor belt sushi restaurants was established, spreading conveyor belt sushi throughout Japan and further popularizing and lowering the price of sushi. By 2021, the conveyor belt sushi market had grown to 700 billion yen and spread outside Japan.
