Sapporo Revolving Sushi restaurants, also known as "kaiten-zushi" or conveyor belt sushi restaurants, have an interesting origin that can be traced back to Japan. While I can't provide a specific origin story for a particular restaurant in Sapporo, I can give you a general overview of the concept's history.
The concept of conveyor belt sushi was first introduced by Yoshiaki Shiraishi in the 1950s. Shiraishi was inspired by the idea of making sushi more accessible and affordable to a wider audience. He devised a system of rotating conveyor belts with small plates of sushi dishes that traveled around a counter. Customers could simply pick the plates they wanted as they passed by, and then they were charged based on the number and type of plates they consumed.
This novel dining concept quickly gained popularity in Japan and later spread to other parts of the world. Sapporo, being one of Japan's major cities, naturally became home to many conveyor belt sushi restaurants. These restaurants not only offer a cost-effective way to enjoy fresh sushi but also provide a fun and interactive dining experience.
While I don't have information on a specific origin story for a Sapporo revolving sushi restaurant, it's safe to say that they are a part of the broader Japanese culinary tradition that has become a global phenomenon, making sushi more accessible and enjoyable for people from all walks of life.
