Conveyor belt sushi

Lore & Background

Conveyor belt sushi was invented by Yoshiaki Shiraishi (1914–2001), who had problems staffing his small sushi restaurant and had difficulties managing the restaurant by himself. He got the idea after watching beer bottles on a conveyor belt in an Asahi brewery. After five years of development, including the design of the conveyor belt and the speed of operations, Shiraishi opened the first conveyor belt sushi restaurant, Mawaru Genroku Sushi, in Higashiosaka in 1958, eventually expanding to up to 250 restaurants all over Japan. By 2001, his company had just 11 restaurants. Shiraishi also invented a robotic sushi served by robots, but this idea has not had commercial success.

Conveyor belt sushi revolutionized the sushi dining experience by making it fast, affordable, and accessible. The concept spread widely after a conveyor belt sushi restaurant served sushi at the Osaka World Expo in 1970, sparking a boom. Further booms occurred in the 1980s as eating out became more popular, and in the late 1990s after the burst of the economic bubble, when inexpensive restaurants gained popularity. By 2010, Akindo Sushiro was the most famous conveyor belt sushi brand in Japan. The system has evolved to include RFID tags to remove old sushi, touchscreen ordering, and automated delivery trays. In 2023, incidents of unhygienic pranks dubbed 'sushi terrorism' led to arrests and public concern, prompting attention from Japan's Ministry of Agriculture, Forestry and Fisheries.
