Decadent, rare, and profoundly luxurious, 28-Day Dry-Aged Otoro (Premium Cut) represents the absolute apex of tuna craftsmanship. Cut from the fattiest, most prized section of bluefin tuna belly, this Otoro undergoes an exacting 28-day dry-aging process that only a handful of specialists can execute safely and consistently.
 
Our store is one of only five places in the United States that professionally dry-age fish, operating under rigorously controlled temperature, humidity, and airflow. Over 28 days, moisture is gently reduced while natural enzymes refine texture and amplify umami - transforming pristine fat into a cleaner, silkier melt and elevating flavor depth without any fishiness.
 
Trimmed to a chef-grade premium cut, this Otoro delivers unmatched marbling, clarity, and elegance - designed for the most discerning sashimi and nigiri experiences.
