Egg sandwiches have become a staple in Japanese convenience stores, gaining attention even overseas. Beyond the classic egg salad, there’s a wide array of unique sandwiches to explore.

In this article, we introduce seven types of sandwiches commonly found at FamilyMart, ranging from familiar favorites to slightly unconventional options.

Classic egg sandwiches: perfect for a light meal

Sandwiches are simple, but the choice of bread and fillings can greatly influence their taste and satisfaction. FamilyMart offers a variety of sandwiches ideal for when you’re feeling a bit peckish.

Whether it’s an egg sandwich or a lettuce-packed option, these selections are perfect for a light snack.

“Egg” sandwich

Egg sandwiches are ubiquitous, found not just at FamilyMart but throughout the country. The term “egg sandwich” encompasses various styles, from mashed boiled eggs mixed with mayonnaise to thick omelets.

FamilyMart’s version features the classic egg salad style, where the sweetness of the eggs is complemented by the tanginess of mayonnaise. However, the tartness is not overpowering, achieving a rich and well-balanced flavor.

“Tuna & Egg” sandwich

The “Tuna & Egg” sandwich combines two popular fillings—egg salad and tuna salad (known in Japanese as tsunamayo, from the words “tuna” and “mayonnaise”)—making it perfect for those who want to enjoy multiple flavors at once.

Tsunamayo, a favorite in rice balls, pairs excellently with sandwiches. At FamilyMart, finely chopped onions are added to the tsunamayo, providing a delightful crunch and enhancing the overall taste.

“Lettuce, Ham, Cheese” sandwich

For health-conscious individuals looking to increase their vegetable intake, the “Lettuce, Ham, Cheese” sandwich is a great choice.

While it includes ham and cheddar cheese, the generous amount of lettuce takes center stage. You could even say that the crisp texture of the lettuce is the sandwich’s defining feature.

The tangy French dressing adds a refreshing finish, embodying the essence of a light and satisfying sandwich.

“Ham & Cucumber” sandwich

The “Ham & Cucumber” sandwich, filled with ham and sliced cucumber, offers a unique twist in its seasoning.

The mayonnaise, which forms the core of the flavor, is mixed with a hint of mustard, imparting a subtle spiciness that tantalizes the taste buds. This combination is sure to have you reaching for another bite!

Hearty meat sandwiches for a satisfying meal

FamilyMart also caters to those seeking more substantial sandwiches. These hearty options, rich in flavor and generous in portion, are sure to satisfy both hunger and taste.

“Pork Cutlet” sandwich

The first thing you’ll notice is the thick cutlets of highly-regarded Sangen pork, which promise a delicious bite even before you dig in. Its appearance alone makes it hard to resist.

The thick-cut pork is juicy, with the fat of the meat perfectly complementing the sweet sauce. While it’s delicious as-is, heating it up makes the cutlet even juicier. You can ask the cashier to warm it up for you.

Once heated, the “Pork Cutlet” sandwich delivers an exquisite taste that deepens with every bite.

It’s amazing to think that such a satisfying sandwich is available 24 hours a day at FamilyMart.

“Teriyaki Chicken & Egg” sandwich

The sweet and savory teriyaki sauce is the key to the flavor of the “Teriyaki Chicken & Egg” sandwich, another staple at FamilyMart.

The soy-based sauce is notably sweet and carries a hint of smokiness. The generous coating of this sauce on the chicken adds a luxurious touch.

Enhancing the sandwich’s heartiness are the egg salad and boiled egg. The richness of the eggs combined with the teriyaki sauce creates a deeply flavorful experience.

Fruit-filled sweet sandwiches

Fruit sandwiches, believed to have originated in Japan, are also available at FamilyMart.

The whipped cream, containing mascarpone, strikes a balance between sweetness and a refreshing taste.

Combined with the juicy fruits, each bite offers a high level of satisfaction.

FamilyMart also offers regional and seasonal limited-edition sandwiches.

With continuous updates and fine-tuning of ingredients and flavors, there’s always something new to discover.

This means that the best time to purchase is when you find them in-store. Don’t miss the opportunity to try these diverse sandwiches!
