Japan is the one country where the grocery shop is a destination in itself, because it runs on three separate systems. The **konbini** (7-Eleven, Lawson, FamilyMart) is for now: a hot snack, a rice ball, an egg sandwich. The **supermarket** (Life, Ito-Yokado, Seiyu, OK) is for cooking and for the pantry. The **depachika** — the food basement of a department store — is for the thing you will photograph before you eat it. Knowing which one you are standing in decides whether a Japanese food shop is the best hour of the day or an expensive bowl of nothing.

## The three shops, and what each one is for

**Konbini** are everywhere and open 24 hours. They are not just snacks: the rice balls (*onigiri*), the tamago sando, the hot case by the register and the in-store coffee are all made to a standard that would be a premium shop elsewhere. In winter they add a pot of **oden** (fish cake, daikon, egg simmered in dashi) by the till.

**Supermarkets** are where locals do their weekly shop. This is where the pantry staples live, and where you find the regional shelves that stock whatever the prefecture is known for.

**Depachika** sit under the big department stores (Isetan, Mitsukoshi, Takashimaya, Daimaru). They are the most expensive and the most impressive: counters of wagashi, bento and prepared food. Almost every depachika cuts prices on prepared food in the last hour before closing, which is the only cheap way to eat there.

## Pantry staples that justify the suitcase space

**Mentsuyu** is noodle soup base, concentrated. Dilute it for soba and udon or use it straight as a dipping sauce. It is the single most useful bottle to bring home because it covers a whole category of meals, and supermarket own-brand versions are good.

**Ponzu** is citrus-and-soy, lighter, used on grilled fish, steamed vegetables and as a dressing. **Goma dare** is the sesame sauce that arrives with shabu-shabu; buy it as a jar and it becomes a dressing for cold noodles and blanched greens.

**Dashi** in its easiest form is a granulated or teabag-style stock. The teabags are the practical version — one bag in a litre of water, then discard.

**Kewpie mayonnaise** is in every supermarket and tastes different from the western version: richer, with more egg yolk. **Furikake** — dried seasoning for rice — comes in dozens of flavours and is light and unbreakable.

**Japanese curry roux** is sold as a block of squares. House Vermont and Java Curry are the two brands you will see most; the difference is mostly spice level. One box makes a large pot and packs flat.

## What is actually in season, month by month

**Spring** is *takenoko* (bamboo shoot) and *sakura mochi*, and strawberry season peaks alongside it.

**Summer** brings *edamame* and cold *somen*, and supermarkets push anything that can be eaten chilled.

**Autumn** is the strongest season for food: *sanma* (Pacific saury), *matsutake* mushrooms, chestnuts (*kuri*) and new rice.

**Winter** is oden, *mikan* (mandarins), crab and *fugu*. Convenience stores ride this hardest — the oden pot and the steamed bun case both appear in late autumn.

## The practical bits nobody mentions

**Plastic bags are no longer free.** Since 2020 shops charge for them. Bring a tote; nobody will look at you strangely, and every shop sells a cheap reusable bag at the till.

**Cash still matters**, though less than it did. Cards are fine at supermarkets and konbini in cities. Smaller shops, many restaurants and some market stalls are cash-only.

**There is no tipping**, and staff will chase you down the street to hand back change you have left.

**Tax-free shopping** is a separate procedure with its own rules and a minimum spend. We cover it in [Japan tax-free shopping](https://clevertourists.com/resources/japan-tax-free-shopping-tourist-rules-and-process) — note that food you consume in Japan no longer qualifies.

**You bag it yourself** at the counter after paying, at a separate bagging table, which is why nobody is standing at the till doing it for you.

## What not to bother with

Fresh fruit is sold in ways that surprise visitors — sometimes single pieces in protective foam. It is excellent and it is priced as a gift, not as a snack.

Anything sold as a souvenir box at a tourist attraction costs more than the same thing in a supermarket one street away.

Liquid-heavy items (sauces, drinks) are usually cheaper and easier to buy at a shop near the airport on the way out than to carry for two weeks.

## Frequently asked questions

### Can you buy groceries at a Japanese convenience store?

Yes, and for a short trip it is enough. Konbini sell rice balls, sandwiches, hot snacks, drinks and basic toiletries, open 24 hours, and accept cards.

### What food is worth bringing home from Japan?

Things that are concentrated, dry or sealed: mentsuyu, ponzu, curry roux, dashi teabags, furikake and Kewpie mayonnaise. They are light, survive the flight and cannot be found at home.

### Do Japanese supermarkets charge for bags?

Yes. Plastic carrier bags have been charged since 2020, so bring a tote or buy a reusable bag at the till.

### Is Japanese supermarket food cheaper than eating out?

Considerably, and prepared food in department-store food halls is marked down in the last hour before closing.
