We developed TUNA SCOPE, the world’s first AI capable of discerning tuna quality with the eye of a skilled artisan.Using the peculiarities of deep learning,the AI was able to establish its own methodology for making judgments that had been considered ‘tacit knowledge’ based on human intuition and experience, becoming the world’s first AI to successfully acquire a professional skill.

In 2020,TUNA SCOPE has been introduced to Kura-Sushi, the largest sushi chain in Japan.With strict COVID-19 travel restrictions preventing its staff from going abroad to purchase tuna as usual, Kura-Sushi succeeded in AI-driven remote purchasing of high-quality stock by sending the app to plants overseas.Its new ‘AI-Tuna’ product was sold in 461 stores, tripling previous sales figures. Tuna Scope caused a major stir around the world, with coverage by more than 1,500 media outlets in 57 countries, as a digital transformation of quality judgment and a solution for overcoming the pandemic.
