Eat Cheaper in Japan: Supermarkets vs Konbini

The konbini is on every corner and open all night, and you pay for that. A supermarket a few streets away sells the same bottle for much less, and in the evening its bento get stickers.

In short

In the government’s price survey the konbini is the dearest shop for every food item: green tea costs 1.6 times the supermarket’s price.
In the evening, supermarkets mark down bento and sushi: first so many yen off, then 半額, half price.
Take it away and the tax is 8%; eat in and it’s 10%.
Konbini staff heat your bento at the till; hotel rooms are a fine place to eat it.

How much more does a konbini cost?

Japan’s Statistics Bureau compares the same products across kinds of shop. In 2024 the konbini was the most expensive for every one of them, and drugstores were often cheaper than supermarkets.

	Supermarket	Konbini
Green tea, a 525–600 ml bottle	100	163
Ice cream, a 200 ml cup	100	144
A bar of chocolate	100	124
Sliced bread	100	114
Milk, 1 litre	100	109
Beer, a 350 ml can	100	108

The supermarket’s average price is 100, and each konbini price is shown against it. National averages for 2024.

Tip: Drugstores sell drinks and snacks too, and in 2024 they were cheaper than supermarkets for most of the same food: bread by about 9%, chocolate by 8%.

Evening discount stickers

Bento, sushi and deli food are made for the day. As the evening goes on, staff cover them in stickers: first a set amount or a percentage off, then 半額, half price.

Temaedori: Japan asks shoppers to take the item at the front, closest to its date, rather than reach to the back. Shelves carry the sign てまえどり.

Department-store food halls before closing

Department stores keep their food halls, the depachika, in the basement. Their sushi, tempura and salads are pricier than a supermarket’s, and some counters mark them down as closing time nears.

Eat in or take away: 10% or 8%

Food you take away carries the reduced 8% tax; food eaten in the shop, like any meal out, 10%. Alcohol is always 10%.

8% · 10% — Take away · eat in

So a konbini with seats will ask whether you’re eating in. Say so if you are: the price at the till changes.

The microwave, and dinner in your room

Buy a bento in a konbini and the cashier will offer to heat it. Nod at 温めますか, atatamemasu ka, and it comes back warm, with chopsticks.

Supermarkets often have a microwave by the bagging counter or the eat-in corner.
Hotel rooms are a fine place for a bento dinner; many business hotels have a microwave in the lobby.
In a ryokan with dinner included, eat the inn’s dinner: bringing your own to the dining room isn’t done.
