What do people get wrong about 100-yen shops in Japan?

This answer is a draft. It stays unpublished until legal review and source verification are complete.

These shops appear on almost every visitor's list, usually described as somewhere cheap. The numbers say something more interesting.

The market, in numbers

Teikoku Databank's industry survey estimates the domestic 100-yen shop market at about ¥1.11 trillion for fiscal 2025 — the third consecutive year above ¥1 trillion. The four largest chains operate roughly 9,400 stores, up more than 200 on the year and 1.4 times the count of a decade ago.

The driver, according to the same report, is the ¥150–¥500 price tier: DIY tools, outdoor goods, functional housework items, beauty tools, stationery and craft supplies. Growth came from specificity and quality, not from staying at ¥100.

[Verify] Figures are from Teikoku Databank's fiscal-2025 outlook (published April 2026). Confirm before publication.

Misunderstanding 1｜Everything costs ¥100

Most shops now carry ¥300 and ¥500 lines alongside the standard range. Check the tag rather than assuming.

Misunderstanding 2｜The price on the shelf is what you pay

Since April 2021 shelf tags must show the tax-inclusive price, so a '¥100' item is labelled ¥110 (10% tax; 8% on food). The '100' in the name is a nominal price - you pay ¥110 or more at the till.

Misunderstanding 3｜It is the same product everywhere

Ranges differ by chain and branch, and lines rotate quickly. An item you saw once may not be there next time.

Misunderstanding 4｜Buy first, work out the use later

The items worth carrying home solve one specific annoyance you already have. Ask whether it solves something at home, not whether it is cheap.

Misunderstanding 5｜Anything can go in your luggage

Knives and blades cannot travel in hand luggage (small round-tipped scissors with blades under 6 cm are usually allowed), and liquids are restricted. Check your airline's rules, and your own country's import rules, before buying.
