The words printed on a Japanese drugstore box are not marketing copy. 化粧品, 医薬部外品, 第3類医薬品, 第2類医薬品, 第1類医薬品 and 要指導医薬品 are statutory classifications under Japan's Pharmaceuticals and Medical Devices Act, and each one carries a different legal answer to a question you are about to face: may you pick this up and carry it to the register yourself, or must a licensed person be involved first?
That is why the shelf layout of a Tokyo drugstore looks arbitrary and is not. The glass case near the counter, the shelf with the printed sign asking you to consult staff, the aisle where nobody bothers you — those are three different legal regimes, and the box tells you which one you are standing in before anyone speaks to you.
This guide explains the classification system and nothing else. It does not recommend, compare or name products to buy, it gives no dosage or usage instruction, and it is not medical advice of any kind — if you need to know what to take, the pharmacist standing three metres away is the correct answer and is legally the person the system is built around. Equally, do not assume that a product legally sold in Japan may legally be carried into your own country. Japan's classification tells you what a product is under Japanese law. It tells you nothing about the customs and drug-control law of the country you are flying to.
What do the box words mean?
Every 一般用医薬品 and 要指導医薬品 sold in Japan must print its category on the package in a prescribed form, so the classification is always visible before you reach the till. The Tokyo Metropolitan Institute of Public Health sets out the format: the words 要指導医薬品 appear inside a frame, and the OTC classes appear as 第1類医薬品, 第2類医薬品 or 第3類医薬品 with the number in Arabic numerals inside a square box, at a minimum of 8 point unless the product name itself is smaller (Tokyo Metropolitan Institute of Public Health, checked 7 September 2026). Roman and Chinese numerals are prohibited for the class number, so the digit you see will always be 1, 2 or 3.
One variant is worth spotting because it looks like a printing quirk and is not. A 指定第2類医薬品 (designated Class 2) is still labelled 第2類医薬品, but the numeral 2 is additionally enclosed in a circle or a second frame. That extra ring is the whole signal.
The table below maps each word to what it legally is and what it means for you at the register.
| Word on the box | What it legally is | At the till |
|---|---|---|
| 化粧品 (cosmetic) | Cosmetic; claims limited to a fixed list of permitted expressions | Take it yourself, no staff involvement |
| 医薬部外品 (quasi-drug) | Quasi-drug; mild action, approved active ingredients, approved claim | Take it yourself, no staff involvement |
| 第3類医薬品 | Class 3 OTC medicine, lowest risk tier | Take it yourself; staff advise only if you ask |
| 第2類医薬品 (incl. 指定第2類) | Class 2 OTC medicine; designated Class 2 has a ringed numeral | Take it yourself; pharmacist or registered seller may sell |
| 第1類医薬品 | Class 1 OTC medicine, highest OTC risk tier | Pharmacist only; written information provision is required |
| 要指導医薬品 | Requires pharmacist guidance; new switches, potent drugs | Pharmacist only, with guidance; not a self-serve purchase |
Two of those rows are the ones that change your behaviour. For 第1類医薬品 the pharmacist must provide the necessary information using a written document, and for 要指導医薬品 the pharmacist must give pharmaceutical guidance before the sale, assessing your situation rather than simply handing the box over (City of Sakai, checked 7 September 2026; Shizuoka Prefecture, checked 7 September 2026).
The gradient below that is real but softer. For 第2類医薬品 the seller is required to make an effort to explain; for 指定第2類医薬品 the shop must actively prompt you to check the contraindications or consult a professional, typically by signage at the shelf; and for 第3類医薬品 the seller responds if you ask and is not otherwise obliged to volunteer anything.
Why is that shelf locked?
The locked glass case and the awkwardly placed high shelf are legal requirements, not shop policy, and they map exactly onto two of the six categories. Under the store structure and layout rules explained by municipal drug-affairs offices, 要指導医薬品 and 第1類医薬品 must be displayed inside the counter at a distance of at least 1.2 metres from the counter, or in a locked display fixture, or otherwise arranged so that the purchaser cannot take the product directly in hand (City of Fukuoka, checked 7 September 2026).
指定第2類医薬品 carries a lighter version of the same idea. It must be displayed within 7 metres of the information-provision fixture — the consultation counter — so that a customer picking one up is physically near someone qualified to answer. The categories must also be displayed separately from one another rather than mixed on a single shelf.
Once you know this, the drugstore reads differently. If a product is behind glass, it is almost certainly Class 1 or 要指導, and the correct move is not to look for another shelf but to go to the counter. If a shelf has a sign asking you to consult, you are in designated Class 2 territory and within 7 metres of the person who can answer. And if you are in an open aisle stacked high with boxes, you are in Class 2, Class 3, quasi-drug or cosmetic territory, where nobody is required to speak to you at all.
What changed in May 2026?
Japan revised its medicine sales rules with effect from 1 May 2026, and two of the changes are visible from the customer side of the counter. The Ministry of Health, Labour and Welfare has published both in its own explainer (MHLW, checked 7 September 2026).
The first is a new named category, 指定濫用防止医薬品 (designated abuse-prevention medicines). Six active ingredients previously handled under the looser heading of "medicines with a risk of abuse" were moved into this formal class: ephedrine, codeine, dihydrocodeine, bromovaleryl urea, pseudoephedrine and methylephedrine. Products containing them now come with specific point-of-sale duties. The pharmacist or registered seller must confirm the purchaser, provide information, and check whether the buyer is also purchasing the same or other abuse-prevention medicines elsewhere. Where someone buys several units, or a single large-volume pack, the seller must confirm the reason.
The age rule is the sharpest edge. MHLW's implementing notice 医薬発1226第16号 of 26 December 2025 sets the threshold at under 18, and MHLW's public explainer states that young purchasers below the age limit may buy only one small-volume box (MHLW notice PDF, checked 7 September 2026). The notice defers the exact permitted quantities to a subsequent ministerial notification, so treat "one small pack" as the shape of the rule rather than a figure to argue over at a counter.
The second change concerns method. These sales must be conducted in person or through a system carrying live two-way video; the notice explicitly excludes methods where the other party's image cannot be seen in real time, naming telephone-only, document-only and chat-based exchanges as insufficient. In practice that rules out buying such a product from an unattended self-checkout.
The third change runs the other way and loosens a long-standing restriction. 要指導医薬品 was historically the one category that could not be sold online at all, because it required face-to-face pharmacist guidance. Under the 令和7年 amendment, effective 1 May 2026, a pharmacist may provide the required guidance by online consultation, judging case by case whether that is appropriate; some products still require in-person confirmation (MHLW reference material, checked 7 September 2026). For a visitor standing in a Tokyo shop this changes little, since you are there in person anyway, but it explains why English-language articles written before 2026 flatly state that 要指導医薬品 can never be sold online.
Cosmetic or quasi-drug?
The difference between 化粧品 and 医薬部外品 is a difference in what the maker is legally allowed to claim, and the label itself tells you which regime a product sits in. A quasi-drug must carry the words 医薬部外品 on the package — or 指定医薬部外品, or 防除用医薬部外品 for pest-control products — and where the product is a designated quasi-drug it must also state the names and quantities of its active ingredients (Tokyo Metropolitan Institute of Public Health, checked 7 September 2026).
Quasi-drugs are defined by law as items with a mild action on the human body, used for purposes such as preventing nausea, bad breath or body odour, preventing rashes and similar skin conditions, preventing hair loss, promoting hair growth, removing hair, and controlling pests. Approval is granted against ministry standards for the specific approved effect, which is why a quasi-drug package can state a defined purpose in a way a cosmetic package cannot.
Cosmetics run on a different logic entirely. Rather than approving each claim, MHLW publishes a closed list of permitted efficacy expressions — 56 of them, under notice 薬食発0721第1号 of 21 July 2011, ranging from cleansing scalp and hair to providing moisture to skin, with the 56th item permitting a claim about making fine lines caused by dryness less noticeable (MHLW notice PDF, checked 7 September 2026). Anything outside that list is not a cosmetic claim, and a product that needs to say more has to be a quasi-drug or a medicine instead.
The compensating rule is disclosure. Cosmetics must display, in principle, all compounded ingredient names on the direct container, along with the manufacturer or distributor's name and address, the product name and the manufacturing number, with limited exceptions for very small products and samples (Tokyo Metropolitan Institute of Public Health, checked 7 September 2026). So the practical test on the shelf is quick: a long full ingredient list and no category word means cosmetic; the words 医薬部外品 mean quasi-drug; a boxed 第1類 / 第2類 / 第3類 numeral means medicine.
How does tax-free work now?
Japan's tax-free system for visitors is in the last weeks of its current form, and the rules you will meet depend on whether you shop before or after 1 November 2026. Both the Japan Tourism Agency and the National Tax Agency have published the change in advance, and the date is fixed in the 令和7年度 tax reform.
Until 31 October 2026 the system works by exempting the sale at the point of purchase. Under the National Tax Agency's rules, 消耗品 (consumables) — a category that explicitly includes 薬品類 and 化粧品類, that is medicines and cosmetics — qualify when a single purchaser's same-day total at the same shop is at least JPY 5,000 and no more than JPY 500,000 excluding tax, and the goods must be packaged in the designated sealed manner and exported within 30 days of purchase (National Tax Agency Q&A and 定義 PDF, both checked 7 September 2026). General goods have the same JPY 5,000 floor and no stated ceiling.
From 1 November 2026 the mechanism inverts. You pay the tax-inclusive price at the shop, present your passport and the goods to Customs at the airport or seaport before check-in, and the tax is refunded only once Customs confirms the export (Japan Tourism Agency, traveller page, checked 7 September 2026).
The table below compares what you must satisfy under each system, since your trip may straddle the boundary.
| Requirement | Until 31 Oct 2026 | From 1 Nov 2026 |
|---|---|---|
| Minimum spend, one shop, one day | JPY 5,000 excl. tax | JPY 5,000 excl. tax, unchanged |
| Consumables ceiling | JPY 500,000 excl. tax | Abolished; category distinction removed |
| Sealed packaging (特殊包装) | Required for consumables | Abolished |
| When you pay the tax | Not charged at purchase | Charged at purchase, refunded after Customs |
| Deadline to leave Japan | 30 days for consumables | 90 days from purchase |
Two consequences matter for a drugstore run in particular. First, the sealed bag disappears, which removes the awkward situation where cosmetics and medicines bought for use during the trip were legally supposed to stay sealed until departure. Second, you must physically have the goods with you when you get the Customs confirmation. The Japan Tourism Agency's traveller page is explicit that the items must be in your possession and that you cannot retrieve them from checked baggage for the check, which means a drugstore haul needs to survive as cabin baggage through the confirmation step rather than being surrendered at the airline desk first.
Can you take it home?
Whether a product may leave Japan and whether it may enter your own country are two separate legal questions, and Japan only answers the first. For ordinary quasi-drugs and cosmetics no Japanese export permission is involved. For controlled substances the position is strict: MHLW states that a person prescribed medical narcotics must apply in advance to the regional Narcotics Control Department for permission both to carry them out of Japan and to bring them back in, and that psychotropic medicines above certain quantities require documentation of medical necessity (MHLW, checked 7 September 2026).
The second question is the one that catches travellers, and the Japanese government answers it only by warning that it cannot answer it. The same MHLW page states that depending on the destination country, you may need to carry documents such as a physician's certificate, that there may be limits on the quantities you can bring in or take out, and that advance permission may be required. Its practical instructions are to carry medicines in their original containers, to avoid carrying quantities beyond your own needs for the trip, to carry them personally rather than posting them, and to check the destination country's rules in advance.
Read that carefully and the implication is unavoidable. Some ingredients that sit in open Japanese drugstore aisles are controlled elsewhere. This guide does not list which countries restrict which ingredients, because the only authority on that is the destination country's own customs or health agency, and no Japanese source consulted here publishes such a list. The verification step is yours: identify the active ingredients printed on the package — Japanese law requires medicines and designated quasi-drugs to state them — and check them against your own country's authority before you fly.
What should you do at the till?
Reading the label solves most of the problem before you queue, and the remaining decisions come down to a short sequence. Work through it in the shop rather than at the register.
- Find the category word on the front of the box: 化粧品, 医薬部外品, or a boxed 第1類 / 第2類 / 第3類医薬品 numeral. If the numeral 2 sits inside a circle or a double frame, it is a 指定第2類.
- If it is a cosmetic or a quasi-drug, you are done. Carry it to the register; no professional involvement is required by law.
- If it is Class 2 or Class 3, you may also carry it to the register. Ask a question if you want one answered — for Class 3 the staff respond on request rather than volunteering.
- If you cannot physically pick the product up, or it is behind glass, it is Class 1 or 要指導医薬品. Go to the counter and expect a pharmacist, a few questions, and written information. Expect it to take longer.
- If nobody at the counter is a pharmacist, a Class 1 or 要指導 sale cannot legally proceed at that moment. That is not a refusal of service; it is the licence boundary. Come back when a pharmacist is on duty or try a pharmacy.
- Photograph the ingredient panel before you leave, especially for medicines. You will need those names to check your own country's import rules, and the packaging may be discarded before you fly.
- For tax-free, keep the purchase in cabin baggage and know which system applies to your purchase date. Before 1 November 2026 the tax comes off at the register; from that date you pay it and reclaim it after Customs confirmation at departure.
There is a matching list of things this system does not give you, and stating it plainly saves time. There is no requirement for the statutory category words to appear in English, so a shop's English shelf signage is a courtesy rather than a legal label. There is no central register of which Tokyo drugstore has a pharmacist on duty at a given hour, so Class 1 availability at 23:00 is a per-branch question you can only answer by asking. There is no official English list of Japanese OTC ingredients restricted in other countries. And there is no reading of the classification system that substitutes for a professional: the entire architecture of six categories exists to route certain questions to a pharmacist, which is a strong hint about where to take yours.
The single most useful sentence to carry into a Tokyo drugstore is therefore not a product name. It is this: the word on the box is a legal status, the legal status decides who may sell it to you, and the shelf it sits on is the law made visible. Learn the six words and the shop stops being a wall of unfamiliar packaging and becomes a sorted, readable system — which is exactly what the regulator built it to be.
