A little late to this, but I wrote about the future of conveyor-belt sushi for The Japan Times. It lacks conveyor belts:
“In October, U.K. sushi chain Yo! Sushi opened a new kaiten (conveyor belt) restaurant in a Florida mall. It is the third branch the chain has established in the United States this year, and more branches are slated to open in 2016. It is a reminder that this automated approach to dining continues to intrigue eaters outside of Japan.
Yet in its birth country, kaiten sushi is changing. Kappa Sushi, one of the major chains, debuted a new restaurant in September in Tokyo’s Aoyama neighborhood called Sushi Nova. Since then, new locations have opened in Asakusa, Harajuku and Shibuya.”
