Yoshiaki Shiraishi was having trouble at his sushi restaurant. He could
not find enough staff to help all his customers. One day, he
noticed beer bottles on a conveyor belt at a beer factory; he realized he could
borrow this idea for his restaurant.
He had to research how to set up the conveyor belt first. For example, he
did experiments to find the ideal conveyor belt speed. He decided 8cm per
second was best. He also noticed that customers held their chopsticks in their
right hand. This meant the conveyor belt should turn in a clockwise direction,
so customers could easily grab plates with their left hand.
Following five years of development, Shiraishi’s
first conveyor belt sushi restaurant opened in Osaka in 1958. Now, people can
enjoy fresh and tasty sushi at conveyor belt sushi restaurants all around the
world.
