Japanese Bluefin Tuna Belly Nagasaki 10lb

What is this Bluefin?
This is premium farm-raised bluefin tuna from Takashima in Nagasaki, cultivated in the nutrient-rich waters off Kyushu and known for its clean flavor, beautiful color, and texture. This piece is a belly block (harakami / 腹一番), the fatty underside that yields the finest cuts — otoro (大トロ) and chutoro (中トロ) — each rich and melting.

Even the leaner parts of the belly carry depth and umami, free of tough sinew or off odors, and the fat dissolves smoothly on the palate. Grown over several years with careful feed management, Takashima bluefin is prized for its consistency in size, color, and taste. Each piece is approximately 10 lbs.

How to enjoy

A belly block gives you both otoro and chutoro from one piece. Slice against the grain for sashimi, or lay it over rice for nigiri, where the fat melts as you eat it. A light sear (aburi) suits the fattier otoro. It needs little more than soy and wasabi. As a large block, it portions into several servings — slice only what you'll eat and keep the rest cold and sealed.

Pairing notes — soy and wasabi, warm sushi rice, grated daikon, and a dry sake.
