The Crown Jewel of Fatty Sashimi: Ōtoro
When asking which sashimi has the most fat, the definitive answer is Ōtoro, specifically from the belly of a bluefin tuna. This premium cut, known as toro, is celebrated for its extreme marbling and exceptionally high fat content, which can exceed 25%. Sourced from the underside of the fish closest to the head, Ōtoro has a pale pink, almost white coloration, a visual indicator of its dense, flavorful fat. Chefs and connoisseurs prize it for a uniquely sweet and rich flavor that is often described as buttery, literally melting away on the palate. Its intense, concentrated umami makes it one of the most expensive and sought-after delicacies in Japanese cuisine.
A Balanced Approach: Chūtoro
Situated between the super-fatty Ōtoro and the leanest cut, Akami, is Chūtoro, or medium-fatty tuna. Chūtoro comes from both the belly and back sections of the tuna, offering a balanced blend of both fat and lean meat. With a fat content typically between 15–20%, Chūtoro provides a satisfyingly rich flavor and a tender yet slightly firmer texture than Ōtoro. Many people find this cut to be the perfect compromise, delivering a harmonious mix of the meaty taste of akami with the luxurious fat of toro.
Other Noteworthy Fatty Sashimi Options
While tuna belly takes the top prize, several other fish offer deliciously fatty sashimi cuts. Salmon, particularly the belly cut, is a popular and readily available option known for its abundant omega-3s and silky texture. King or Chinook salmon is especially high in fat, making it a favorite for many chefs. Yellowtail (Hamachi) is another excellent choice, prized for its rich, oily flavor and high fat content, which is best during its peak season. Mackerel (Saba) also contains a significant amount of healthy fats and is often served cured (Shime Saba) rather than raw to balance its strong flavor.
The Health Benefits of Fatty Fish Sashimi
The fat in these prized sashimi cuts isn't just for flavor; it's a rich source of highly beneficial omega-3 fatty acids, specifically EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid). These essential nutrients are crucial for supporting heart health, brain function, and overall well-being. For instance, a serving of fatty salmon can provide a substantial portion of your daily omega-3 needs, contributing to reduced inflammation and improved cardiovascular function. Healthline reports that fatty fish like salmon and tuna are excellent sources of omega-3s for better heart health.
How to Identify and Enjoy Fatty Sashimi
Identifying fatty sashimi is often a straightforward process. Look for the white, buttery marbling that streaks through the flesh, similar to how it appears on a high-grade cut of beef. This marbling is more pronounced in Ōtoro and Chūtoro, while the fattiness in salmon belly is typically softer and more evenly distributed. When enjoying these cuts, they are best served simply to let the natural flavor and texture shine. A light dip in high-quality soy sauce is usually all that is needed, with wasabi used sparingly to complement, not overpower, the rich taste.

Conclusion: A Delicate Balance of Flavor and Fat
When exploring the world of sashimi, knowing which sashimi has the most fat is key to understanding its flavor and texture profile. While Ōtoro stands as the undisputed champion, the nuances between it, Chūtoro, and other fatty favorites like salmon and yellowtail offer a range of delicious experiences. From the intense richness of Ōtoro to the harmonious balance of Chūtoro, each cut provides a delightful and healthy way to enjoy the rich omega-3s and unique characteristics of fresh seafood. The high fat content not only enhances the taste but also contributes to the sashimi's coveted silky texture and nutritional value.
