The Magic of the Japanese Convenience Store Sandwich

Sharing is caring!

There are over 50,000 convenience stores in Japan – sometimes it seems you’re no more than about 500 steps from one of them – and, while they sell all sorts of fun items to investigate, it’s the food – and particularly the sandwiches, that thrill most tourists. But why? Why is the Japanese Convenience Store Sandwich so iconic…

Wait – You Want Me To Eat Where?

I hear you.

Depending on where you are from in the world, the idea of visiting a convenience store might not sound like a key holiday attraction, let alone a viable dining choice. But the 7-11 and other convenience stores in Japan, like Family Mart and Lawson, are nothing like the convenience stores you might be used to back home.

They’re spotlessly clean and well stocked, and the food aisle is full of everything from snacky onigiri (hunks of rice with filling—there’s a picture below) to full takeaway meals prepared fresh every day.

Some convenience stores – known as konbini – even have seating areas in which to consume your meal.

This is why popping in for snacks and a nose around the chocolate aisle of a konbini, is one of the main things on our list of small things you must do on your Japan trip.

But of all the cool things you’ll find in the food aisles of a kombini, the piece de resistance is the sandwiches.

Helpfully, if you’re trying to order one, the Japanese word for sandwich is サンドイッチ – pronounced sandoiichi

And of all the places you might eat a sandwich in Japan, the konbini sandwiches, are a thing of magnificence with a cult-like following on various Japanese Facebook groups. And, once you taste one, you’ll (probably) also join the cult.

My obsession is such that when I’m traveling solo to Japan, I usually don’t do anything the first night. Instead, I spent the first night in my hotel to get over the flight and pick up a convenience store egg sandwich, a Zima ‘beer’ (something I become obsessed with traveling in the US, but that you can now only buy in Japan) and whatever crisps look exciting on the day.

It’s become my little ritual.

I’m not alone. Japanese Facebook groups rave about them, and during the Tokyo Olympics, one reporter’s discussion of his convenience store food purchases of the day was getting more love than his reports on the events! Even Hollywood celebrities have to have one – although Eugene Levy went off-piste and got his egg sandwich from a store renowned for giant egg sandwiches!

So, Why Are the Sandwiches So Amazing?

In a world of artisan sourdough and sandwiches piled high with exotic toppings, I admit, when you first see the Japanese sandwiches lined up on the shelf, you might wonder what all the fuss is about.

They’re not very thick, the toppings squish against the plastic packaging, and they’re (usually) made from the type of sliced white bread that it’s definitely not fashionable to be seen putting in your shopping basket!

But, you know what they say about judging books and covers and all that… use that now.

I’m not a food writer for a reason. I can’t describe food in glowing terms, explain what it is about the taste that makes the Japanese sandwich experience so different from anywhere else, and definitely can’t do it lyrically—but I can look at facts, and so, rather than trying to waffle on about tastes, I decided to investigate why these things taste so good. And it seems it all starts with…

The Bread

The bread on most convenience store sandwiches is standard white sliced bread, but it’s squishier and fluffier than that type of bread elsewhere.

The reason is that the Japanese use a special way of cooking dough for their bread, known as yudane.

In this, the flour and water are mixed together and then cooked which causes the starch in the dough to change structure and become more chewy and gelatinous.

They also usually cut the crusts off for you, which, technically, makes the sandwich less healthy but means you don’t have any of the normal ‘ugh, there’s no filling left, and this bit’s boring, but I guess I have to eat it anyway’ that you get with a normal sandwich.

The Fillings

These vary depending on which store you’re in, but there are over 20 different flavors of convenience store sandwiches. Among them, though, are a few stand-out classics.

The Egg Sandwich

This is my first choice every time. The filling is soo creamy.

It’s simply roughly processed eggs (so the chopped whites and yolks mix together) mixed with Japanese Kewpie Mayonnaise, which is much creamier than the mayo you’re probably used to.

The combination is a thing of beauty.

Some brands offer egg sandwiches with more whole-formed eggs in them – but personally, I just go for the mushy ones! I hate boiled eggs in their natural form.

The Tonkatsu Sandwich

If you’re looking for a more substantial Japanese convenience sandwich, this is the one to pick. You can also have these heated up by the staff.

If you like this one, also look for the Shrimp Cutlet with Sauce. Imagine the topping from a prawn toast between bread!

There’s also a Chicken Cutlet if you don’t like or eat pork.

Ham and Potato Salad

Do not knock this one until you’ve tried it.

I picked this up in a hurry one day, thinking it was ham and coleslaw. When I got back to the hotel, I was not impressed, but I’d walked about 20km that day, and I wasn’t going back out again, so it was going to be eaten—and it was amazing.

Also, watch out for the Ham and Cucumber one. Simple yet deceptively tasty.

And, if you want your spuds to play more of a starring role, you’ll find ‘plain’ Potato Salad Sandwiches.

As you can see, the sandwiches are also a good option if you don’t like fish and have been worried about how you’ll manage in Japan – the good news it there’s a lot more than you might think. Find a list of fish-free dishes to choose here.

Veggies Watch Out

A note to vegetarians: Despite being labeled as ‘potato salad,’ these often contain small pieces of ham. You might also find that sandwiches labeled ‘salad’ or ‘lettuce’ also have meat, so look or read things carefully.

The Strawberry and Cream Sandwich

Yes, it’s whipped cream and strawberries between two slices of bread.

It took me a few trips to try this one, and I’m not sure I need to do it again.

There’s nothing wrong with it, but if I’m going to finish my meal with something sweet it would be of the chocolate variety.

It is a very iconic, only in Japan, experience though – and others rave about them the way I do the egg option.

You might also find other fruit-based sandwiches with options like oranges, peach or kiwi. If you’re vegan you don’t have to miss out. There’s a vegan fruit sandwich shop in Asakusa – find the details in our Tokyo itinerary

If you can’t make your mind up, you’ll also find multipacks that might let you taste two, or even three, options in one handy packet!

How Much Are They?

Eating in a konbini is one way to save money on your trip. And the great thing about the sandwiches is that they are pretty cheap (usually around 250-400 yen).

They are quite light, so, if you have a big appetite, you might want to treat them as a snack rather than a meal – or, buy two and/or something else to go with them like an onigiri or one of the many other things you’ll find on the shelf.

Who Makes the Best Egg Sandwich in Japan?

After sampling all of the options, multiple times, I have to say I agree with Antony Bourdain, Lawson just has the edge – then Family Mart, then 7-11 – but, 7-11 has better side dishes to go with it. Their little pots of salad are really interesting – and let you get in a vegetable which can be harder than you think in Japan!

How to Order Your Sandwich?

It couldn’t be easier!

The exact name is written on the front in Japanese, but also in English (if that surprises you, then have a look at our post on where English is commonly used in Japan) so you know exactly what you’re signing up for.

You’ll even find calories on the back if such things concern you when you travel.

The price is the first number on the pack – so 276円 – in the example above. 円 is the symbol for yen.

But, Japan has an extra tax which is 8 percent on food and drink – so, the actual price you’ll be charged is the second figure – 298円 for the pack above.

Convenience stores will always ring your purchases up on the till so you’ll get a ‘written’ total anyway. I find them a great place to get rid of some of the many, many small coins you pick up in Japan as you know exactly how much to give the server.

Depending on what you’ve ordered when you get to the counter, the staff might ask you a question – if you hear the words atatamemasu ka? they are asking if you would like it heated.

Say Hai (pronounced like hi) – or nod – if you do. If not just say iie (pronounced like eee-e).

If you want to eat your sandwich now, either head to one of the seats if the store has them, or, eat it outside the shop.

Not only is this polite – you shouldn’t eat while walking in Japan – it’s likely to be the only place you’ll find a bin to throw away the rubbish. Leave at your peril or your bag could end up with an egg sandwich wrapper in it for hours!

A Last Sandwich Thought…

There’s one last reason I love convenience store sandwiches in Japan. A reason that has nothing to do with how they taste or what’s in them…

Some nights on a trip, I don’t want to go out and eat – and can’t even manage to stagger to one of the local chains that are my go-to when I’m tired.

I just want to sit and let my poor achy feet recover. I want to have a bath in my hotel room (Japanese hotel rooms nearly always have baths) or use the onsen if the hotel has one, relax and plan the next few days.

If I do this while enjoying some local goodies from the 7-11 and watching Japanese television, I don’t feel like I’m missing out on some kind of ‘authentic’ experience.

I’m just doing the same as a lot of Japanese people that evening – eating a quick, tasty meal from the konbini while watching TV – and that’s alright with me.

If sandwiches aren’t your thing, you can also get fried chicken – Family Mart’s FamiChicki is voted the top by those in the no. Or, pick up a ready meal… and have it heated up for you. There’s so many dishes to choose from.

So, have you tried a Japanese convenience store sandwich on one of your trips – or, do you think I’m mad even suggesting the idea in a country with so many Michelin-starred restaurants and must-try dishes?

    If you sit to eat/drink inside the sales tax is 10%, not 8%. If you don’t say in advance when paying that you will eat inside you and then you sit down to eat you will get quickly asked to leave, as technically you (and likely the combini itself) could be considered to be evading taxes.
