Tuna sushi is served on a conveyor belt at the “Kura Sushi” chain in Tokyo, Japan, March 13, 2023. The Japanese conveyor belt sushi chain said on Monday that they started using an artificial intelligence camera system early this month to catch unhygienic pranks after a video of a man licking a soy sauce bottle filmed at one of their restaurants in central Japan went viral online.
