Japanese tuna is raw. Italian tuna is cooked.

Pretty much, yeah. Japan’s culinary tradition treats tuna as an ingredient best raw or barely seared — sashimi, nigiri, tataki. The fish is prized for its pristine freshness, silky texture, and subtle flavor. Italy, on the other hand, almost always cooks tuna. You see it grilled, pan-seared, confit, or packed in olive oil (tonno sott’olio) for pasta, salads, and antipasti.

The difference comes down to how each culture values the fish. In Japan, the ritual is about the ocean-fresh flavor of the flesh itself. In Italy, tuna is a richer, more robust ingredient — cooked or preserved to intensify its meatiness.

There’s overlap, sure. Italy has raw tuna preparations (like crudo or carpaccio) and Japan does cook tuna (like in nitsuke or katsu). But those are exceptions that prove the rule. Walk into a traditional Italian trattoria and ask for raw tuna — you’ll get a funny look. Walk into a traditional sushi-ya and ask for grilled tuna — same thing.

The lesson: respect the tradition, and you’ll get the best version of each
