What happened
Sushiro, IT giant Fujitsu, and Kiyo subsidiary Kuroshio Suisan are launching a cross-industry demonstration in Sukumo Bay, Kochi Prefecture, using ocean tech to support aquaculture, with Sushiro pledging to buy all the fish produced.
Why it matters
The move signals that a major conveyor-belt sushi chain sees cross-industry partnerships as necessary to keep supplying fish, as aging workers and rising sea temperatures make single-company efforts insufficient.
WHO IT HITSThis affects aquaculture workers and seafood supply chain managers, who may see new technology-based approaches to fish farming as labor challenges and rising sea temperatures strain traditional methods.

The demonstration brings together a conveyor-belt sushi chain, an IT company, and a fisheries subsidiary to test whether ocean tech can help sustain aquaculture. Kuroshio Suisan, a subsidiary of Kiyo, provides the site in Sukumo Bay, where it currently operates 130 fish pens. The push comes as Japan's fishing and aquaculture workforce ages and sea temperatures rise, making it harder to deliver seafood to the table. At the same time, global demand for Japanese seafood is growing on the back of sushi's popularity. Individual companies have tried to tackle these problems, but the partners argue that single-company efforts have limits; hence the cross-industry approach. The panel discussion was held at CEATEC 2026, an event organized by JEITA.
