Study Notes
Sushi Train Invention
- Yoshiaki Shiraishi invented the sushi train (kaiten zushi) in Osaka, Japan nearly 70 years ago.
- Yoshiaki was inspired by a tour of a bottling factory where he saw bottles moving along a conveyor belt.
- He encountered three main problems:
- Materials: He tried wood, thick paper, and iron, but these were not suitable for the constant cleaning. He finally settled on stainless steel.
- Corners: Right-angled corners led to plates getting stuck or falling off. He solved this by using half-moon shaped pieces of steel to create a "fan" shape around the corner.
- Speed: He found that a speed of 8 centimeters per second was ideal.
- The sushi train was designed to be in a "U" shape to fit Yoshiaki's restaurant and allow for the maximum seating capacity.
- The sushi train moves clockwise because most Japanese hold chopsticks in their right hand, allowing them to easily pull plates from the sushi train with their left hand.
