Our Wild Bluefin Tuna Akami Saku Block is cut from the lean loin section (akami) of wild-caught bluefin tuna and trimmed into a traditional saku block for sushi and sashimi preparation.

Akami is the most classic and widely used bluefin cut in sushi bars, valued for its deep ruby color, clean ocean flavor, and firm texture. Unlike fattier bluefin cuts, akami delivers a pure, focused tuna experience that highlights freshness and technique rather than richness.

This saku block gives you complete control over slice thickness and presentation—ideal for sashimi, nigiri, or crudo. It’s a refined, everyday sushi cut that performs consistently and cleanly.

Akami vs Otoro: What’s the Difference?

Bluefin tuna offers several distinct cuts, each with its own character:

Akami (This Product)

• Cut from the lean loin
• Deep red color (retained by tasteless smoke process)
• Clean, mild tuna flavor
• Firm texture

Ideal for sushi, sashimi, and everyday raw preparations

Otoro (Our Premium Cut)

• Cut from the fattest belly section
• Pale pink with heavy marbling
• Ultra-rich, buttery mouthfeel
• Considered a luxury, indulgent experience

If you’re looking for purity and balance, akami is the traditional choice.
If you’re seeking maximum richness and indulgence, our Bluefin Otoro is the upgrade.

Both cuts serve different roles—and neither replaces the other.

Why Choose Bluefin Akami?

Akami is preferred when you want:

• Clean, focused tuna flavor

It’s the backbone of classic sushi menus worldwide.
