Creamy egg salad is sandwiched between fluffy slices of shokupan bread to create Tamago Sando, a Japanese egg sandwich. You can easily recreate this iconic Japanese convenience store item at home!
I'll share a simple convenience store version and a gourmet kissaten (old-school coffee shops in Japan) version with whole boiled eggs inside.
As I grew up in Japan, tamago sando might be the first sandwich I ever had, and I've enjoyed it so many times when eating out. My parents made homemade tamago sando for Sunday lunch.
It's a popular item in konbini (Japanese convenience stores), and you can grab one at many konbini across Japan, even late at night (yes, really). I use Kewpie mayonnaise to recreate nostalgic flavor.
This recipe is part of my Japanese konbini from scratch series, where I recreate my Japanese convenience store favorites at home, including: Natto Maki and Tuna Mayo Onigiri. Make sure to check them out too for a Japanese konbini experience at home.

What Is Tamago Sando?
Tamago sando is a Japanese egg salad sandwich made with Kewpie mayonnaise based egg filling and fluffy Japanese soft bread called shokupan (食パン).
Tamago sando is one of the most popular sandwiches in Japan, along with tuna mayo sando. "Tamago" means eggs and "sando" is for sandwich. It gained popularity through tourist reaction to Japanese convenience store tamago sando.
The filling is usually made with hard-boiled eggs and Kewpie mayonnaise to create a creamy texture.
Another key component is shokupan, Japanese milk bread. Japanese shoupan is a little bigger than standard sandwich bread in the US. It has a significantly fluffy and pillowy texture that gently hugs the filling inside. The convenience store tamago sando is usually served with its crust cut off to emphasize the fluffiness.
Egg salad sandwich is the most popular style of tamago sando, but some stores have Tamagoyaki (Japanese rolled egg omelette) as a filling.
Why Is Tamago Sando So Popular in Japan?
Tamago Sando is popular and widely enjoyed in Japan because it's delicious and affordable. You can grab them anywhere in Japan 24/7 at convenience stores like 7-Eleven Japan, Lawson, and FamilyMart. It's an easy grab-and-go food at the train stations.
You can also grab gourmet versions at cafes and bakeries. A konbini egg sandwich is light and great for a snack. But a gourmet tamago sando at a cafe is fulfilling enough for a meal.
Konbini Tamago Sando vs. Cafe Tamago Sando vs. Homemade
Tamago sando comes in many styles in Japan, and each one has its own charm. The convenience store style, cafe style, and homemade style are all very delicious in their own ways, but they serve a different purpose and feel.
Konbini tamago sando is THE tamago sando, and has an iconic style. You can find them in any convenience store like 7-Eleven, Lawson, and FamilyMart, and they all look and taste close to each other. It's often made with crustless, thin yet fluffy bread and creamy uniform egg salad filling. It's light and easy, great for a snack and light meal with sides and coffee.
Cafe tamago sando feels something more special. At kissaten (喫茶店), Japanese old-school cafes, and modern coffee shops, you may see a sandwich made with thicker and bigger slices of bread, more filling, chunkier egg salad, or even a thick Japanese omelette instead of egg salad. Some come in hot dog style.
Homemade tamago sando is close to konbini style but more homey. Made with shokupan and homemade tamago salad. It's more flexible and can be adjusted to your liking. Either way, making it at home is so simple and easy.
For this recipe, I'll share how to make a simple homemade version inspired by Japanese convenience store tamago sando and how to turn it into a gourmet cafe version.
Why Is Japanese Egg Sandwich Different from Western Egg Salad Sandwich?
Japanese egg sando tastes different from a Western egg salad sandwich because of fluffy shokupan and Kewpie mayo based filling.
Japanese egg sando filling usually has no herbs or vegetables. But Kewpie mayonnaise makes it so rich and satisfying. And the Japanese milk bread makes this sandwich extra pillowly.
Ingredients
- Eggs: Use large eggs for the egg salad filling. I use hard-boiled eggs for the classic tamago sando filling, and added soft-boiled eggs for the gourmet-style version.
- Kewpie Mayo: I highly recommend Kewpie mayonnaise for this recipe, like a lot of Japanese families make their sando at home. It makes the sandwich taste more like Japanese tamago sando. But you can also use your favorite mayo.
- Rice Vinegar: A small amount of rice vinegar adds brightness and balances the richness of the eggs and mayonnaise. You can also add lemon juice for bright acidity.
- Shokupan: Shokupan, or Japanese milk bread, is the best bread for tamago sando because it is soft, fluffy, and slightly sweet. If you cannot find shokupan, use the softest white sandwich bread you can find.
- Butter: Softened butter adds richness and helps protect the bread from the egg salad filling.
- Karashi: Karashi is Japanese mustard. It is optional, but it adds a spicy kick! Karashi is very spicy compared to regular yellow mustard, so a little goes a long way! I use karashi powder and mix it with water before use. Karashi powder usually lasts longer in my pantry than paste tubes.
- Salt and Pepper: Keep the seasoning simple. Salt brings out the flavor of the eggs, and pepper adds a little spicy kick.

Best Bread for Tamago Sando
The best bread for tamago sando is shokupan, Japanese milk bread, because it is pillowy soft, slightly sweet, and big enough to hold creamy egg filling.
What If I Cannot Find Shokupan?
I understand the struggle! Because I live in a Midwest suburb, it's really hard to find one for me too.
First, try your local Asian grocery store. In their bakery section or frozen section, you might find one there.
If there is a Japanese, Asian, Korean, or French-style bakery nearby, take a look there. They might have soft milk bread.
If not, don't worry! You can use soft white sandwich bread as the closest substitute. I personally like sourdough or crusty bread even though you won't quite get the Japanese tamago sando feel, but it still tastes delicious and hearty.
Should You Cut Off the Crusts?
Yes, if you want yours to be as soft as Japanese convenience store tamago sando. But no if you don't mind a crust or you're making a hearty gourmet version.
How to Make Konbini-Style Tamago Sando at Home
- Bring a pot of water to a boil. For hard-boiled eggs, cook eggs for 12 minutes, and for soft-boiled eggs, cook for 8 minutes. Transfer to an ice bath to cool, then peel.
- Separate the egg yolks and whites of hard-boiled eggs.
- Chop the egg whites finely and set aside.
- In a bowl, add the egg yolks, mayonnaise, and rice vinegar. Use a fork to mix until creamy. Then stir in egg whites. Season with salt and pepper.
- Spread the butter and karashi on one side of each slice of bread.
- Add half of the egg salad to the buttered side of one bread slice and spread it toward the edges, leaving a thick layer in the center. Top with the other slice of bread. Repeat with the remaining ingredients.
- Wrap the sandwiches in plastic wrap or parchment paper. Let them rest for 5-10 minutes. Slice into halves or quarters.
Tips for Success
- Mixing egg yolks with mayonnaise before adding egg whites creates a creamy texture.
- You can chop egg white finely for a smooth filling, or chop roughly for a chunky texture. Adjust for your liking.
- Butter creates a barrier between the bread and filling, preventing a soggy sandwich.
How to Make Gourmet Cafe Style Tamago Sando
When making a gourmet sando, toasting your bread is also a delicious option, adding tasty flavor!
Also, make the filling a little bit saltier than convenience style, as extra whole eggs will be added. Also season the soft-boiled eggs on the cut surface before enjoying.
- After adding the egg salad layer, add 2 soft-boiled eggs on top of the egg salad layer. Top with the other slice of bread.
- Wrap the sandwiches in plastic wrap or parchment paper. Let them rest for 5-10 minutes. Slice into halves.
- Season the cut surface of soft-boiled eggs well with salt and pepper after cutting.
Tips for the Creamiest Tamago Sando Filling
For the creamiest tamago sando filling, mix just egg yolks and mayonnaise first. The yolks become smooth and rich when mixed with Kewpie mayonnaise, and this creates the creamy base of the filling.
I like to chop the egg whites separately, then fold them into the yolk mixture. This gives the filling a creamy texture while still leaving chunky pieces of egg for a satisfying texture.
Common Tamago Sando Problems and Fixes
Why Is My Egg Filling Watery?
Egg filling can become watery if you add too much liquid. Do not add too much rice vinegar or lemon juice.
Why Is My Tamago Sando Soggy?
Tamago sando can become soggy if the filling is too loose. Make sure the egg filling is creamy but not runny.
A thin layer of butter on the bread can also help protect the bread from moisture, especially if you are making the sandwich ahead of time.
Why Is My Sandwich Hard to Cut Cleanly?
Tamago sando needs to be set to be cut cleanly. After assembling the sandwich, wrap it in plastic wrap or parchment paper and let it rest for 5-10 minutes. Then use a sharp knife to cut through.
Tamago Sando Variations
- Konbini-Style Tamago Sando: Made with the creamy filling and soft white bread or shokupan, and the crusts are cut off for a Japanese convenience store-style sandwich.
- Cafe-Style Tamago Sando: Keep the egg filling a little chunkier and add more filling for a thicker sandwich. Use thick slices of bread, toasted bread, or hot dog buns.
- Atsuyaki Tamago Sando: Instead of egg salad, use thick Japanese rolled omelette or dashimaki tamago as the filling. Spread Kewpie mayo on the bread to add richness and a touch of tartness.
- Jammy Egg Tamago Sando: Add a soft-boiled egg in the center for a beautiful cross-section.
- Karashi Tamago Sando: Add a small amount of Japanese mustard for a sharper flavor. Karashi goes really well with creamy egg filling.
- Cucumber Tamago Sando: Add thinly sliced cucumber for freshness and crunch.
- Ham Tamago Sando: Add a thin slice of ham with the egg filling for a simple Japanese-style sandwich variation.
What to Serve with Tamago Sando
Tamago sando makes a fulfilling meal with a few sides and a drink! Try these recipes to pair with your homemade sando.
- Drinks: I love to pair sandwiches with a glass of matcha like Banana Matcha Latte, Strawberry Matcha Latte, or refreshing Matcha Lemonade.
- Sides: Add fun sides to make it even more fulfilling, like Karaage, Sunomono, and green salad with Japanese Sesame Dressing.
- Soups: Shio Koji Tomato Soup and Miso Soup.
- Desserts: Hanami Dango, Ichigi Daifuku, and Mitarashi Dango.
How to Store Tamago Sando
Tamago sando tastes best the day it is made, while the bread is still soft and the filling is fresh.
If you have leftovers, wrap the sandwich tightly in plastic wrap or place it in an airtight container and store it in the refrigerator. Enjoy it within the same day for the best texture.
The bread can dry out or become soggy as it sits, so I do not recommend storing tamago sando for too long.
If you want to make it ahead, prepare the egg filling in advance and store it in the refrigerator. Assemble the sandwich closer to serving so the bread stays soft and fresh.
