Japanese Tuna Egg Sandwich Ingredients
To make a mouthwatering Japanese tuna egg sandwich, you’ll need a few key ingredients.
These items are easy to find and come together to create a flavorful dish. We’ll examine what’s required and the importance of each component.
Essential Ingredients for the Tuna Mixture
High-Quality Tuna
Using good-quality canned tuna is crucial. Look for options packed in water or oil, depending on your preference.
Why Quality Matters
The better the tuna, the tastier your sandwich will be. Freshness makes a noticeable difference in flavor.
Choosing Between Water and Oil
Tuna packed in water is lighter, while oil-packed tuna is richer. Pick based on your desired taste and calorie count.
Creamy Mayonnaise
Mayonnaise is a must-have for binding the tuna mixture. It also adds a rich, creamy texture.
The Best Type of Mayonnaise
Japanese recipes often use Kewpie mayonnaise, which has a slightly sweeter taste than regular mayo.
Adjusting the Amount
Feel free to add more or less mayonnaise based on how creamy you want your sandwich filling to be.
Key Components for the Egg Layer
Fresh Eggs
Fresh eggs are essential for making the soft, fluffy omelette that pairs beautifully with the tuna.
How Many Eggs to Use
For one sandwich, two to three eggs should suffice. This ensures a thick, satisfying layer.
Whisking Techniques
Whisk the eggs thoroughly to avoid lumps. This helps create a smooth, even omelette.

Step 1 – Prepare the Tuna Mixture
The first step in making a Japanese tuna egg sandwich is preparing the tuna mixture. This is the foundation of your sandwich, so take your time to get it right.
Here’s how to make a flavorful and creamy tuna mix.
Mixing the Tuna
Combine Tuna and Mayonnaise
Start by draining the canned tuna and placing it in a mixing bowl. Add a few tablespoons of mayonnaise to bind the mixture.
How Much Mayonnaise?
- For 1 can of tuna (about 5 oz), use 2–3 tablespoons of mayonnaise.
- Adjust based on your preference for creaminess.
Why Mix Thoroughly?
Mixing ensures the mayonnaise coats every piece of tuna, creating a uniform texture. Any big lumps can be broken apart using a fork.
Adding Flavor Enhancers
To elevate the flavor, you can add a pinch of salt, pepper, or even a dash of soy sauce.
Optional Ingredients
- Soy Sauce : Adds umami depth.
- Lemon Juice : Brightens the flavor.
- Green Onions : Adds a fresh, mild kick.
A Quick Taste Test
Before moving on, taste the mixture and adjust the seasoning if needed. This ensures your sandwich will be perfectly balanced.
Tools You’ll Need
Simple Kitchen Tools
You don’t need fancy equipment to prepare the tuna mixture. A mixing bowl and fork are all it takes.

Step 2 – Cook the Perfect Tuna and Egg Omelette
The following step involves preparing the tuna and egg omelette, which contributes a light, airy layer to your sandwich. This step is simple but requires attention to detail for the best results.
Preparing the Egg Mixture
Whisk the Eggs
Break the eggs into a bowl and beat them until they are smooth. Season with a dash of salt and pepper.
Whisking Tips
- Use a fork or whisk for even blending.
- Avoid over-beating to keep the texture light.
Optional Add-Ins
- Milk: Makes the omelette softer.
- Cheese: Adds richness and flavor.
Cooking the Omelette
Heat a nonstick pan over medium-low heat and pour in the egg mixture. Cook gently to avoid browning.
Cooking Tips
- Use low heat to prevent sticking.
- Stir gently while cooking for a soft texture.
When Is It Done?
The omelette is ready when it’s set but still slightly moist. Don’t overcook it!
Combining Tuna and Egg
Layering for Flavor
Once the omelette is cooked, chop it into small pieces and mix it with the tuna mixture.
Why Combine Them?
This creates a cohesive filling that blends the flavors of both components.
Proportion Guidelines
| Ingredient | Amount |
|---|---|
| Tuna Mixture | 1 cup |
| Chopped Omelette | 1/2 cup |
Final Touches
Mix gently to avoid breaking the omelette pieces too much. This keeps the texture interesting.

Step 3 – Assemble Your Japanese Tuna Egg Sandwich
Now that your tuna mixture and omelette are ready, it’s time to assemble your Japanese tuna egg sandwich.
This step is where everything comes together to create a delicious, picture-perfect meal.
Choosing the Right Bread
Soft and Fluffy Bread
The best bread for this sandwich is soft, white bread—often called shokupan in Japan. It’s slightly sweet and perfectly complements the filling.
Why Shokupan Works Best
- Its fluffy texture holds the filling without overpowering it.
- The subtle sweetness balances the savory flavors.
Alternatives to Shokupan
If you can’t find shokupan, any soft white bread will work. Avoid dense or crusty bread, as it can detract from the sandwich’s delicate taste.
Preparing the Bread
Toast the bread lightly if you prefer a firmer texture, or use it as-is for a softer bite.
To Toast or Not to Toast?
- Toasting adds a slight crunch.
- Untoasted bread keeps the sandwich light and airy.
Butter or No Butter?
You can spread a thin layer of butter on the bread for extra richness, but it’s optional.
Layering the Filling
Spread Evenly
Start by spreading the tuna and egg mixture evenly across one slice of bread. Be generous but not excessive.
How Much Filling?
- Use about 1/2 cup of filling per sandwich.
- Adjust based on the size of your bread slices.
Why Even Spreading Matters
Even spreading ensures every bite has a perfect balance of bread and filling.
Adding Extra Layers
For an extra touch, you can add a thin layer of lettuce or sliced cucumbers for crunch.
Optional Add-Ons
- Lettuce: Adds freshness.
- Cucumber: Provides a crisp texture.
Keep It Simple
Stick to one or two extras to avoid overwhelming the main flavors.
Final Assembly
Press Gently
Place the second slice of bread on top and press gently to hold everything together.
Why Press Lightly?
Pressing helps the sandwich hold its shape without squishing the filling.
Cutting the Sandwich
Cut the sandwich diagonally or into neat rectangles for a polished look.
Serving Suggestions
Serve immediately or wrap it tightly for later.

Step 4 – Add the Finishing Touch
The final step in making your Japanese tuna egg sandwich is adding the sauce. This finishing touch enhances the flavors and ties everything together.
A well-made sauce can elevate your sandwich from good to amazing.
Choosing the Right Sauce
Classic Japanese Mayo
Kewpie mayonnaise is the go-to choice for this sandwich. Its creamy texture and slightly sweet flavor make it ideal.
Why Kewpie Mayo?
- It’s richer than regular mayo.
- The sweetness complements the savory filling.
Where to Find It
Look for Kewpie mayo in Asian grocery stores or online. Regular mayo works in a pinch, though.
Optional Sauces
If you want to experiment, try adding a drizzle of tonkatsu sauce or sriracha for a tangy kick.
Tonkatsu Sauce
- Adds a hint of umami.
- Pairs well with the tuna and egg flavors.
Sriracha Mayo
- Mix sriracha with mayo for a spicy twist.
- Perfect for those who like heat.
Applying the Sauce
Drizzle or Spread
You can either drizzle the sauce over the filling or spread it directly on the bread. Both methods work well.
How Much Sauce?
- Start with 1–2 teaspoons and adjust to taste.
- Too much sauce can make the sandwich soggy.
Why Apply Evenly?
Even application ensures every bite has a balanced flavor.
Final Presentation
Garnish for Appeal
For a professional touch, sprinkle a little black pepper or sesame seeds on top before serving.
Why Garnish?
- Adds visual appeal.
- Enhances the flavor profile.
Ready to Serve
Your Japanese tuna egg sandwich is now complete! Serve it fresh for the best taste.

Tuna and Egg as Low-Calorie Proteins
Tuna and eggs are both excellent sources of protein and relatively low in calories. Together, they form the core of this healthy sandwich.

A 5-ounce can of tuna packed in water contains about 120–150 calories. If you opt for oil-packed tuna, the calorie count increases slightly due to the added fat.

Sauce Adds Extra Calories
Kewpie mayonnaise, while delicious, is higher in calories than regular mayo. A tablespoon contains about 90–100 calories. Using it sparingly helps keep the total count in check.
Total Estimated Calories
Per Sandwich
Based on typical ingredient amounts, a single Japanese tuna egg sandwich contains approximately 350–450 calories.
Factors That Affect Total Calories
