Leading conveyor belt sushi chain Kura Sushi will launch a new product, "Kiwami Jukusei AI Tuna," which utilizes the TUNA SCOPE smartphone app for a limited time from July 10.

Kiwami Jukusei AI Tuna utilizes TUNA SCOPE, which learns the "connoisseurship" of skilled tuna artisans and veteran brokers and judges the quality of the tuna with high precision. This is a product that is claimed to be one of the best with even more flavorful ingredients.

According to Kura Sushi Public Relations, the reason for introducing TUNA SCOPE is that the global epidemic of a new type of coronavirus is also affecting business transactions of seafood products. In the past, stockists, together with brokers and fishery companies, visited production areas and processing plants in Japan and abroad to check and share quality.

According to Kura Sushi, TUNA SCOPE makes it possible to sort out tuna with a high degree of accuracy even remotely, making it possible to source only the highest grade A tuna, even in an environment where staff members cannot go.

TUNA SCOPE is an AI application developed by Dentsu and Dentsu International Information Service that uses deep learning to instantly assess the quality of tuna by cross-sections of a large number of "tuna tails" and the results of a craftsman's connoisseurship.

The quality classification by TUNA SCOPE is "A" for the highest grade, "B" for the high grade, and "M" for the rest. These three classifications can be instantly distinguished, and the highest grade, "A", is selected and served to customers visiting a Kura Sushi restaurant as the Kiwami Jukusei AI Tuna.

The price of the Kiwami Jukusei AI Tuna is 200 yen for two pieces (excluding tax). They will be available from July 10 to July 16 and July 22 to July 28. This time, TUNA SCOPE will be introduced on a trial basis to help improve quality.
