If you want to make a Japanese rice bowl at home that combines tender raw tuna with warm rice, Negitoro Don is a simple and satisfying option.
This Negitoro Don recipe is made by finely mincing 200 g (7 oz) of tuna akami, mixing it with 2 tsp mayonnaise, and serving it over rice with green onion, egg yolk, and wasabi. The tare is made with brewed soy sauce, Cheongha, sugar, garlic, and sesame oil. It is briefly boiled, chilled completely, and then drizzled over the bowl little by little to taste. The clean flavor of the tuna pairs with creamy mayonnaise, aromatic green onion, and the sweet-savory tare for a smooth, rich rice bowl.

✓ How to Make Negitoro Don
- Soak the tuna in salted water: Lightly rinse the surface of 200 g (7 oz) frozen tuna akami under running water. Dissolve salt in lukewarm water and soak the tuna in the salted water for 5 minutes.
- Thaw the tuna: Remove the tuna from the salted water and pat it thoroughly dry. Wrap it in plastic wrap and let it thaw at room temperature for 30 minutes.
- Cook the tare: Add 2 tbsp brewed soy sauce, 1 tbsp Cheongha, 1/2 tsp sugar, and 1/2 tsp minced garlic to a small saucepan. Heat the mixture and, once it begins to boil, continue boiling for another 30 seconds.
- Cool the tare: Transfer the cooked tare to a separate container. Stir in 1 tsp sesame oil, then chill it in the refrigerator until completely cold.
- Prepare the green onion: Thinly slice the 10 cm (4-inch) piece of green onion and set it aside for the topping.
- Finely mince the tuna: Slice the thawed tuna akami thinly, cut it into small pieces, then repeatedly chop it with a knife until it develops a fine, soft texture.
- Mix the tuna with mayonnaise: Add 2 tsp mayonnaise to the finely minced tuna and gently mix until evenly combined and smooth.
- Assemble the Negitoro Don: Add rice to serving bowls and generously spoon the mayonnaise-seasoned minced tuna over the top. Add the sliced green onion, egg yolk, and wasabi.
- Serve with the tare: Do not pour all of the chilled tare over the bowl at once. Drizzle it on little by little as you eat, adjusting the amount to your taste.
✓ Key Tips for Success
- Mince the tuna very finely. If large pieces remain, the tuna will not blend smoothly with the mayonnaise and it will be harder to achieve the fine texture associated with Negitoro. Slice the tuna thinly first, then continue chopping it repeatedly with a knife.
- Do not add all of the tare at once. The soy-based tare has a strong flavor and can overpower the delicate taste of the tuna if too much is added at once. Drizzle on a small amount as you eat and adjust the seasoning to your preference.
✓ Serving Tips
- Break the egg yolk just before eating and mix it into the tuna and rice. This adds an even smoother, richer texture to the bowl.
- Instead of mixing all of the wasabi into the tuna, add a small amount to each bite. This makes it easier to adjust the sharp flavor to your preference.
- Start with a small amount of tare and add more only if needed. This helps preserve the individual flavors of the tuna, green onion, and mayonnaise.
✓ How to Choose Good Bluefin Tuna Akami
- Color and sheen: Choose akami with a deep, vivid red color and a natural sheen on the surface. Avoid pieces with noticeable dark discoloration.
- Connective tissue: For sashimi-style akami, pieces with fewer thick, prominent white connective tissues generally have a smoother texture when minced or eaten raw.
- Chilled or frozen condition: Because proper bleeding, gutting, and low-temperature handling after catch are important for maintaining bluefin tuna quality, choose products with intact packaging that have been kept at a stable refrigerated or frozen temperature.

✓ Frequently Asked Questions (FAQ)
Q1. How do you thaw frozen tuna akami for Negitoro Don?
Lightly rinse the surface of the tuna, then soak it in lukewarm salted water for 5 minutes. Pat it dry, wrap it in plastic wrap, and let it thaw at room temperature for 30 minutes before mincing.
Q2. Why does my Negitoro have a coarse texture?
The tuna may not have been minced finely enough. Slice it thinly, cut it into smaller pieces, and then repeatedly chop it with a knife until the texture becomes fine and smooth.
Q3. Is mayonnaise necessary for this Negitoro Don recipe?
This recipe uses 2 tsp mayonnaise to give the minced tuna a smooth, rich texture. To reproduce the same flavor and texture, use the specified amount.
The finished Negitoro Don looks especially appetizing with vivid red tuna, fresh green onion, and a golden egg yolk. Finely minced akami keeps the clean flavor of tuna while the mayonnaise gives it a softer, creamier texture. Thinly sliced green onion adds a fresh aroma and light texture that keeps the rich tuna from feeling too heavy. Once the egg yolk is broken, it makes the tuna and rice even smoother and richer. A small drizzle of soy-based tare, scented with garlic and sesame oil, adds just enough savory depth to balance the bowl.
When I eat tuna rice bowls, I prefer tasting the tuna itself before adding a lot of sauce, so I especially liked serving the tare separately and adding it little by little. Finely chopping the akami and mixing in a small amount of mayonnaise transformed the lean tuna into a smooth, creamy mixture without losing its clean flavor. Eating it with the green onion also added a fresh aromatic note between bites. After breaking the egg yolk and mixing it with the tuna and rice, even the salty notes of the tare became softer and more rounded. My family also enjoyed the combination of finely minced tuna, creamy egg yolk, and sharp wasabi. The ingredient list is simple, but being able to adjust the amount of tare and wasabi as you eat makes this a rice bowl worth preparing again.
If you want a different way to enjoy tuna akami, try this Negitoro Don recipe with finely minced tuna, green onion, and egg yolk. Add the tare gradually rather than pouring it all over the bowl at once so you can enjoy the distinct flavor of each ingredient.
