Continuing Your Medication After Moving to Japan: Chronic Care, Refills, and the Bridge Period

The gap import guides skip: Japanese pharmacies don't honor foreign prescriptions

Almost everything written about medication and Japan is about the airport. How much you can carry, when you need a yakkan shoumei, which drugs are banned. That advice is real and you should follow it, but it answers a short-term question. This article answers the one that starts a few weeks after you land and never stops: how does someone with diabetes, high blood pressure, a heart condition, or any ongoing illness keep getting treated once the supply they brought runs low?

The hard fact that catches new residents off guard is this: a pharmacy in Japan cannot dispense against your home-country prescription. A prescription written by your doctor in California, London, or Sydney has no legal standing at a Japanese pharmacy counter, no matter how valid it is at home. To get your medication here you need a prescription written by a doctor licensed in Japan, and that means becoming a patient of a Japanese clinic and being assessed in person before anything is dispensed. There is no shortcut where you hand over a foreign script and walk out with the same pills.

If you are still in the trip-planning stage rather than relocating, you are on the wrong page, and that is worth saying clearly. Carrying medicine in for a holiday or a long stay is the bringing medication to Japan question: the one-month rule, the import confirmation, the controlled-drug walls. This page picks up where that one ends. You have moved, or are about to, and the goal is not to clear customs once but to keep a chronic condition treated for years inside the Japanese system. The two problems share a border but need different plans, so we keep the FAQs and the advice separate.

The bridge period: what to carry before you have a Japanese doctor

There is a gap between landing and being established with a Japanese clinic, and that gap is where chronic-care plans most often break. The fix is to treat the first stretch in Japan as a bridge you supply yourself, not a problem you solve on arrival.

Bring as much of your own medication as the import rules let you carry, properly documented, so you are not racing the clock to find a doctor. For a planned move that usually means applying for an import confirmation (yunyu kakunin-sho, the document formerly called yakkan shoumei) before you fly, because a few weeks of supply is rarely enough and anything beyond roughly a month per drug crosses into territory that needs the certificate. The mechanics of that application sit in the import guide above; the point here is to start it early, because review can take several weeks and you want the buffer in your suitcase, not stuck in processing.

While you have that buffer, two things need to happen in parallel rather than in sequence. One is getting registered and insured: you register your address at the city or ward office, and enrollment in National Health Insurance generally follows from that registration, often with a card issued the same day if you apply in person. Without insurance you can still see a doctor and get a prescription, but you pay the full cost rather than the usual share, so getting insured quickly matters for a condition that needs ongoing visits. The other is lining up the doctor before the buffer is half gone, not when you are down to the last week. Booking a first appointment, gathering your records, and getting an initial prescription written takes longer than people expect, especially in a new language.

Carry a written, translated picture of your treatment with you, not just the pills. A Japanese doctor taking over your care needs to know the exact drugs, doses, and the diagnoses behind them, and the easiest way to give them that is a clear list in hand on day one. We cover what that document should contain further down, but pack it before you fly rather than trying to reconstruct it from memory at a clinic reception desk.

Finding a doctor to take over a chronic condition

For diabetes, high blood pressure, heart disease, and most stable long-term conditions, the right first stop in Japan is a local clinic, not a big hospital. Understanding how the system is built saves both money and time.

Japan steers routine and chronic care toward neighborhood clinics and keeps large hospitals for specialist and advanced treatment. The system enforces this with money: since October 2022, if you walk into a hospital with 200 or more beds for a first visit without a referral letter, you are charged a selective medical fee of at least 7,000 yen for the initial visit and at least 3,000 yen for a re-examination, on top of your normal share of the bill and not covered by insurance. Individual hospitals can and do set higher amounts. The practical takeaway for someone managing a steady chronic condition is that a local internal-medicine clinic (naika) is usually the correct and cheaper door, and it can write the referral if your case ever needs the hospital.

Language is the real filter, not eligibility. Day-to-day clinic care in Japan runs in Japanese, and a doctor who can manage a complex medication history in English is the exception rather than the rule. Several public directories exist to find one: the Japan Medical Association runs an English medical portal that lists facilities by language and specialty, many prefectures and major cities publish their own multilingual clinic lists, and the AMDA International Medical Information Center can help locate language-capable facilities. Our own guide to finding English-speaking doctors in Japan walks through how to search and what to confirm before booking.

When you do find a clinic, treat the first visit as a handover, not a quick refill. Bring your translated medication list and diagnosis summary, your insurance card once you have it, and any recent lab results you can get. The doctor will assess you in person, decide what to prescribe under Japanese rules, and from then on you are inside the system: regular visits, prescriptions written here, and pharmacies that can finally dispense for you.

When your exact drug doesn't exist in Japan

A common shock is discovering that the specific brand you have taken for years is simply not sold in Japan, or is only available in a different strength or formulation. This is normal, it is decided by a doctor, and it is not something to manage yourself.

Japan approves and markets medicines through its own regulatory system, so the overlap with what is sold in your home country is partial. Some active ingredients are identical and widely available, some are sold only under different brand names, some come in different doses or combinations, and a few are not approved here at all. Where your exact product is not available, a Japanese doctor will look at what you take and decide on an appropriate option available in Japan, which may be a different brand of the same drug, a generic, or in some cases a different drug used for the same condition.

This is the part of the article where we have to be plain about what we are not. Japan Care Concierge does not give medical advice, does not diagnose, and never suggests what a person should switch to or what dose is equivalent. Which medicine replaces which, and at what strength, is a clinical judgment that belongs to the prescribing doctor and the pharmacist who knows the patient and Japanese formularies. If you read anywhere that a particular foreign drug equals a particular Japanese one, treat it as a starting point for a conversation with your doctor, never as an instruction. Bring the generic (international) name of every drug you take, because that is what lets a Japanese clinician identify the closest available option, and let the clinical decision happen in the consulting room.

One reassurance for cost-conscious patients: Japan actively promotes generic substitution, and the pharmacist will often offer a generic version of whatever is prescribed. You can accept or decline, and asking the pharmacist about the difference is normal. Generics keep the out-of-pocket cost of a long-term regimen lower, which matters when a chronic condition means a prescription every month for the rest of your life.

Refills, the medication notebook, and how a Japanese prescription actually works

Once you are established with a clinic, the rhythm of getting your medication differs from many home countries in ways worth knowing before your first prescription, not after.

Two timing rules surprise newcomers. A prescription in Japan is valid for only four days from the date it is issued, including the day of issue, so you take it to a pharmacy promptly rather than holding it for later. And Japan separates prescribing from dispensing: the clinic writes the prescription, and you fill it at a separate community pharmacy (chōzai yakkyoku), not at the clinic itself. Bring the prescription to a pharmacy the same day and you avoid having to go back for a new one.

Refill prescriptions exist but are narrower than the open-ended refills common elsewhere. Japan introduced the refill prescription (rifiru shohōsen) in April 2022 for patients whose condition is stable, at the doctor's discretion. It can be used a maximum of three times in total before a new visit is needed, it is aimed at stable lifestyle-related conditions such as high blood pressure, high cholesterol, and diabetes, and it specifically excludes controlled medicines such as sleeping pills and sedatives, newly approved drugs, and patches. Whether you qualify is the doctor's call, so ask directly whether a refill prescription suits your case, and if it does, use the same pharmacy each time, which the system expects for continuity.

The one document that ties all of this together is the medication notebook, the okusuri techō. It is a small booklet the pharmacy updates at every fill, recording each drug, the dose, and how to take it, and you show it alongside your insurance card whenever you collect medicine. For someone with a chronic condition and multiple drugs it is the running record that lets any pharmacy or new doctor see your regimen at a glance, and it is the single most useful thing to keep current. Ask for one at your first pharmacy visit if you are not offered it.

Translated medical records and the tools that help

The single best preparation for unbroken chronic care is arriving with a clear, translated picture of your treatment that a Japanese doctor can read and act on. This is groundwork you control, and it is worth doing before you fly.

At minimum, prepare a one-page medication list: every drug by its generic (international non-proprietary) name, the dose, how often you take it, and what condition it treats. Generic names matter because brand names rarely carry across borders, and the active ingredient is what a Japanese doctor needs to find the closest available option. Alongside it, a short summary of your diagnoses, relevant history, and recent key test results gives the doctor the context to take over safely rather than starting from zero.

Where your care is complex, ask your current doctor for a referral letter or medical summary, the equivalent of what Japan calls a shōkaijō (referral) or shinryō jōhō teikyōsho (medical information provision document). Having it translated into Japanese before the move smooths the handover and, separately, a referral in hand is what lets you skip the selective medical fee if your case does need a hospital. Professional medical translation services in Japan handle diagnostic summaries, imaging and lab reports, and prescriptions, and for a chronic condition that translation is a small cost against years of continuous care.

For appointments themselves, free help exists. The AMDA International Medical Information Center provides telephone medical interpretation and information on language-capable facilities in several languages, including English; you can reach it at 03-6233-9266. Many municipalities and international associations also run medical interpreter dispatch or phone-interpretation services for residents, and some hospitals provide their own interpreters. Lining up which of these you can call before your first complicated appointment is far better than improvising at the clinic window.

How this connects to insurance, costs, and the language barrier

Continuing your medication is one thread in a larger setup, and it knots together with health insurance, ongoing costs, and the practical problem of managing care in Japanese.

Insurance is the backbone of affordable chronic care here. As a registered resident you join public health insurance, and your share of medical and prescription costs is commonly 30 percent, falling to 20 or 10 percent for older residents, with monthly caps that protect against large bills. How enrollment works, when coverage starts, and how the share changes with age sit in our guide to healthcare for foreign retirees in Japan, which is the right next read once your prescriptions are handled. The wider picture of how to retire and settle here lives in the how to retire in Japan as a senior hub.

The language barrier does not end at the prescription counter. Managing a chronic condition means recurring appointments, lab results to understand, and the occasional change to explain, all in Japanese unless you have arranged otherwise. Our guide to living in Japan without fluent Japanese as a senior covers how people handle exactly this over the long term, from interpreter services to the people who help at the clinic.

Where we fit is the coordination, not the medicine. Japan Care Concierge does not diagnose, prescribe, or advise on which drug to take; those belong to your doctor and pharmacist. What families ask us to help with is the navigation around the clinical care: identifying language-capable clinics in the right area, organizing translated records, arranging interpretation, and being the point of contact when an overseas family is coordinating an elderly parent's care across time zones. If that is the part you are stuck on, our medical coordination service is built for it, and you can reach us to talk through a specific situation.
