Every tourist ends up in a konbini within an hour of landing — it's convenient, it's bright, it's open. But convenience is a product you're paying for. Mio doesn't care that it's easy; here's where the same items actually cost less.
A convenience store (konbini) is unbeatable for one thing: it's open 24/7 and it's everywhere. It's genuinely the right choice for an ATM that takes foreign cards, buying event/transport tickets, printing, parcel drop-off, or a hot meal at 2am. But for the everyday basket — a bottle of water, a bag of snacks, travel-size toiletries — you're typically paying a convenience premium of roughly 20–50% over a drugstore (illustrative, varies by item). If you buy your daily drinks and snacks here for a week, that premium quietly adds up.
Japanese drugstores (Matsukiyo / Matsumoto Kiyoshi, Welcia, Sugi, Cosmos, and others) are far more than pharmacies. They stock drinks, snacks, instant food, cosmetics, sunscreen and over-the-counter medicine — usually at the lowest everyday prices of the three. The tourist bonus: many drugstores offer tax-free shopping once you pass the minimum purchase (generally ¥5,000+ in one store, same day) with your passport. That means buying toiletries and consumables in bulk at a drugstore can beat konbini twice — lower shelf price and no consumption tax.
Daiso and other 100-yen shops (hyaku-en shop) are where you fix travel problems cheaply: travel adapters, umbrellas, phone cables, packing containers, snacks, and souvenirs for about ¥100–300 each. They're not the cheapest place for a week of groceries, but for the "I forgot to pack X" moment they beat a konbini or department store by a wide margin. Note prices are usually shown before tax, so a ¥100 item rings up a little higher.
If you have kitchen access or just want a cheaper lunch, a supermarket (super) beats all of the above on food. The traveller's trick: many supermarkets discount fresh bento, sushi and deli items with half-price stickers in the evening (often after ~7–8pm) as they clear that day's stock. A dinner that would cost ¥800 at a konbini can be ¥300–400 at a supermarket near closing time — illustrative, but the pattern is real.
| Item | Cheapest place | Note |
|---|---|---|
| Water / soft drinks | Drugstore / supermarket | Konbini is 20–50% more; buy multipacks at a drugstore |
| Snacks & sweets | Drugstore | Same brands, lower price; tax-free if basket is big enough |
| Toiletries (travel size) | Drugstore | Buy in bulk once, go tax-free with passport |
| Cosmetics / sunscreen | Drugstore | Widest range and best price; popular tax-free category |
| OTC medicine | Drugstore | Only realistic option; pharmacist may need to advise |
| Travel adapter / umbrella / cables | 100-yen shop | ~¥100–300 vs several times that elsewhere |
| Souvenirs (cheap) | 100-yen shop | Snacks, chopsticks, small gifts |
| Meals / fresh food | Supermarket | Cheapest, and half-price stickers in the evening |
| Anything at 3am / ATM / tickets | Konbini | Worth the premium for 24/7 convenience |
Use the konbini only for what it's uniquely good at — convenience, ATM withdrawals, tickets, and late-night emergencies. Buy drinks, snacks and toiletries at a drugstore (in bulk, and tax-free with your passport if you clear the minimum). Buy travel gear at a 100-yen shop, and buy meals at a supermarket, ideally in the evening. The item is the same; only the meter changes with the door you walk through.
One more lever: how you pay matters too. Some tax-free and discount setups interact with cash vs card — worth knowing before you check out. Cash vs card in Japan →
