Chūtoro sushi
ōtoro sushi

Chūtoro (中トロ) is the name for medium fatty tuna when served in sushi restaurants.[1] A bluefin tuna yields akami (red meat), chūtoro, and ōtoro (大トロ, 大とろ, pink fatty tuna).

Chūtoro is usually found near the skin on the back and belly. It combines the lighter but deep, slightly bitter flavor of an akami with the sweet tenderness of an ōtoro. It is quite expensive and usually served only on special occasions.[1]
