Pharmacies and Prescriptions in Japan

A pharmacy in Japan comes in two everyday forms: the dispensing pharmacy (調剤薬局, chōzai yakkyoku), where a pharmacist fills the prescription your doctor wrote, and the drugstore (ドラッグストア, doraggusutoa), which sells non-prescription medicine alongside everyday goods. If a clinic hands you a prescription, you take it to a licensed pharmacy (薬局, yakkyoku), not to just any shop that sells medicine. If you only have a mild cold and want to wait and see, the Ministry of Health, Labour and Welfare notes that you can buy medicine at a pharmacy or drugstore without going to a hospital. This guide explains how the two kinds of shop differ, how a prescription moves from the clinic to the counter, what the medicine notebook (お薬手帳, okusuri techō) is for, how non-prescription medicine is grouped, and where to look for help in English. It is general information only; for anything about your own treatment, ask the pharmacist or your doctor.

What is the difference between a dispensing pharmacy and a drugstore?

The legal line is dispensing. Under Japan's Pharmacists Act, a pharmacist may not dispense medicine for sale anywhere other than a pharmacy, apart from narrow exceptions such as a hospital's or clinic's own dispensary and some care given in the patient's home (Pharmacists Act, Articles 22 to 25-2, e-Gov). In other words, a prescription from a clinic is filled either in a licensed pharmacy or, where the clinic dispenses in-house, at the clinic itself, and a shop that is not a licensed pharmacy is not the place to take it.

Staffing also differs. The Japan National Tourism Organization's guide for visitors who feel ill points people who do not need a doctor toward a nearby pharmacy or a drugstore, and advises them to consult a pharmacist or a registered sales clerk (登録販売者, tōroku hanbaisha) if necessary. The same guide warns that some types of medicine cannot be bought when the pharmacist is not there, and it notes that after a clinic visit you are charged separately at the pharmacy for any medicine you need, although some medical institutions dispense in-house (JNTO, guide for when you are feeling ill). In practice this usually means two payments: one at the clinic and one at the pharmacy.

When a pharmacist fills your prescription, the law gives that pharmacist specific duties. The Pharmacists Act requires the pharmacist to check any doubtful point with the prescribing doctor before dispensing, to write the patient's name, dosage and directions on the container or packet, and to give the patient the information and guidance needed for correct use. That explanation at the counter is part of the pharmacist's legal role, and it is your moment to ask questions about timing, side effects or anything you did not understand at the clinic.

How does a prescription work, from clinic to counter?

After the examination the clinic gives you a prescription (処方箋, shohōsen). In the public insurance system, the rules that govern insured medical practice set its period of use at four days including the day of issue, unless there are special circumstances such as a long trip (Rules for Insured Medical Institutions and Physicians, Article 20, e-Gov). If you cannot reach a pharmacy within that window, contact the clinic that issued it rather than assuming a pharmacy will accept it late. The same rules also provide for a refill prescription (リフィル処方箋, rifiru shohōsen) that can be used more than once, up to three times, for medicines other than those the Minister excludes; each later use must fall within seven days before or after the end of the previous supply period.

At the pharmacy you hand over the prescription. The pharmacist reviews it, checks with the doctor if anything looks doubtful, prepares and labels the medicine, explains it, and you then pay for the medicine at the pharmacy. The amount you pay reflects your insurance share; the Ministry of Health, Labour and Welfare's patient notice on brand-name drugs, cited in the generics section below, refers to the usual patient share of 10 to 30 percent. Paper slips are no longer the only route, because Japan also runs electronic prescriptions, described in the next section. The table below brings together the main rules from the law and from ministry notices.

What is the okusuri techō, and why carry it?

The okusuri techō is a medicine notebook in which your medication history is recorded and kept. The Ministry of Health, Labour and Welfare explains that showing it to doctors and pharmacists when you see more than one medical institution, or when you have medicine dispensed at a pharmacy, helps prevent drug interactions and duplicate prescribing (MHLW magazine, September 2023 feature on using pharmacies). The same feature encourages patients to write down side effects, effects and bodily changes they notice, which makes the notebook useful as a record you can hand to a doctor who cannot read your home-country files.

The notebook no longer has to be paper. In the same September 2023 feature, the ministry describes electronic versions on a smartphone, which are harder to forget, and links them to electronic prescriptions (電子処方箋, denshi shohōsen), which started in January 2023. With an electronic prescription, the clinic and pharmacy share the prescription through a central system instead of paper; after the consultation you receive a printed copy of the prescription contents carrying an exchange number (引換番号, hikikae bangō), which you use at the pharmacy. The ministry also notes that the system lets doctors and pharmacists check your current medicines even if you forget your notebook. For foreign residents, a sensible habit is to bring the notebook or app to every appointment and to keep a written list, with generic names, of any medicine you brought from abroad.

Generic or brand-name: what changes at the counter?

Where a generic (後発医薬品, kōhatsu iyakuhin; often called ジェネリック, jenerikku) exists for a brand-name drug, the choice now carries a cost. According to the ministry's notice to patients, if you ask for the original brand-name drug when a generic exists, you pay a special charge; from June 2026 that charge equals half the price difference between the brand-name drug and the generic, paid on top of the usual 10 to 30 percent share, and consumption tax is added (MHLW, long-listed brand drugs and the special charge). The ministry's own example uses a brand-name tablet at 100 yen and a generic at 60 yen: the difference is 40 yen, so the special charge is 20 yen per tablet.

When several generics exist, the gap is calculated against the most expensive generic, and costs other than the drug itself, such as consultation and dispensing fees, do not change. Rounding means the charge may not come to exactly half. Because the ministry changed the size of this charge from June 2026, older articles may quote a different fraction; confirm the current amount at the pharmacy counter before deciding.

Which medicines can you buy without a prescription?

Medicines sold without a prescription are called OTC medicines in Japan, and the ministry divides them into two groups. Guidance-required medicines (要指導医薬品, yō-shidō iyakuhin) are products such as those that recently moved from prescription to OTC status, and a pharmacist must give information face to face when selling them. General-use medicines (一般用医薬品, ippan'yō iyakuhin) come in Class 1, Class 2 and Class 3; a pharmacist must provide information for Class 1, while Class 2 and Class 3 can be bought from either a pharmacist or a registered sales clerk (MHLW, 2026 revision of the medicine sales system). That is why a drugstore without a pharmacist on duty may have some products it cannot sell at that hour.

A revision taking effect on May 1, 2026 tightened sales of six ingredients now called designated abuse-prevention medicines (指定濫用防止医薬品), which include ephedrine, codeine, dihydrocodeine and pseudoephedrine. Pharmacies and drugstores must now check with the buyer and give information; buying several packs, or even one large pack, requires stating a reason; and young people under a set age can buy only one small pack, sold face to face or by video call by a pharmacist or registered sales clerk. The same revision lets a pharmacist decide to sell guidance-required medicines online after an online consultation, except items that still need a face-to-face check. For symptom-by-symptom help with reading Japanese packaging, see the separate over-the-counter medicine guide on this site.

How can you get help in English at a pharmacy?

Language support varies from shop to shop, so it helps to search before you go. The ministry's national medical information service, Iryō Jōhō Net, nicknamed Navii (医療情報ネット), lets you search pharmacies as well as hospitals and clinics across Japan, and its pharmacy search includes a foreign-language option; the site itself offers English, Chinese and Korean menus (MHLW Iryō Jōhō Net (Navii)). The ministry's September 2023 magazine feature, cited above, described the national system ahead of its April 2024 launch as able to search for pharmacies across prefectures and to support voice reading and multilingual translation. Listings can change, so confirm the language available that day with the pharmacy itself.

According to the same JNTO guide for visitors who feel ill, cited in the first section, visitors can also use the Japan Visitor Hotline, a 24-hour multilingual call center run by JNTO at 050-3816-2787. Its scope covers emergencies such as illness and includes introductions to medical institutions that consult in foreign languages; it supports English, Chinese and Korean, and as a general rule it does not provide three-way interpretation. If symptoms are severe, that JNTO guide lists 119 as the number to call when someone is seriously sick or injured. At the counter itself, showing your okusuri techō, a written medicine list or the packaging from home saves a great deal of explanation, and it is reasonable to ask the pharmacist to write the dosing times down if spoken instructions are hard to follow.

Can you bring your own medicine into Japan?

Often yes, within limits. The ministry's English notice for travelers says you may bring medicines for personal use without applying for import confirmation up to set amounts: prescription drugs up to a one-month supply, and other drugs and quasi-drugs up to a two-month supply (MHLW, bringing medicines for personal use into Japan). Above those amounts, you must apply for import confirmation and receive it before leaving home, then show it to the customs officer. Prescribed narcotics and stimulants' raw materials follow separate, stricter rules and need permission from the directors of the Regional Bureaus of Health and Welfare before departure, and prohibited or controlled narcotics cannot be brought in at all. Rules and forms change, so confirm with the ministry or the relevant regional bureau before you travel, and once you live in Japan, ask a local doctor whether a medicine available here can replace what you brought.
