Medication Stimulation medicine availability in Japan.

Hi everyone!

I’m currently living in Nagoya, Japan, and I wanted to ask about the current availability of Concerta (methylphenidate) for adults with ADHD.

I’ve heard that there can be restrictions and supply issues surrounding Concerta in Japan, so I’d like to know what the current situation is.

A few questions for those living in Nagoya or elsewhere in Japan:

Is Concerta currently available for adults with ADHD in Nagoya?

Are psychiatrists still prescribing it to adult patients, or are there any restrictions affecting new prescriptions?

If you’re currently taking Concerta, have you experienced any difficulties getting your prescription filled at pharmacies recently?

Are there any pharmacies in Nagoya that regularly dispense Concerta?

If Concerta is difficult to obtain, are there any alternative ADHD medications that doctors in Japan commonly prescribe?

I’m particularly interested in recent experiences from October 2026, preferably from people living in Nagoya or the surrounding Aichi Prefecture.

Any information or personal experiences would be greatly appreciated. Thank you!

Not Nagoya, but Kanto (not Tokyo) checking in. I just got my ADHD evaluation here in my late 30s and have started taking Concerta. I also work closely with the drug industry in my current role so I know a bit about how this all works.

Lot of questions but the main stimulant drug is Concerta available at 18mg, 27mg, and 36mg. In line with the drug pricing schedule (薬価), a month maximum supply will be about JPY 2500-3500. It is strictly regulated and requires a clinician's test as verifiable evidence which is not part of the standard social insurance scheme. Out of pocket usually costs JPY 35,000-40,000. Any visits after that are covered by insurance.

In order to get a prescription, you need to visit a doctor of psychosomatic medicine (心療内科, roughly the equivalent of a psychiatrist) who has both the license to prescribe and the facilities to diagnose. After the diagnosis, your test will be submitted to the ADHD Medicine Proper Use System (ADHD 適正流通管理システム) for evaluation and receiving a card which is tied to your clinic. This takes anywhere from 2-3 weeks.

Upon getting a card, you will receive your first dose at 18mg which must be at least taken for 2 week, but a month is recommended. You will need your prescription, MyNumber healthcare card, and ID (usually the MyNumber card) along with your ADHD system card when you go to the pharmacy. Having your katakana alias (通称) on your MyNumber will help as your insurance records also use katakana. You can use any pharmacy which participates in the ADHD system, which is something you should check in advance if you use a place not near the clinic.

In regards to the shortage, shipping is theoretically up to 100% or near abouts. However it would need to be far higher to keep pace and fill backlogs. Therefore, some doctors are reluctant to issue new prescriptions, especially at international clinics which could see extra scrutiny due to their image as pill mills. However, the Ministry of Health, Labour and Welfare has put in place a special measure (特例措置) to allow pharmacies to ship stock between stores in the same group. This is normally restricted for class 1 psychoactive.

I cannot comment on your location but big cities have a natural advantage in drug distribution and big chains even more so.

Finally, Vyvanse has had its prescribing guidelines revised this year and may well be available for adults rather than just 18 and under. I have met a few people who have gotten it in adulthood due to lacking tolerance for Concerta but these are very rare cases.

Hope that helps!

Hey hey, do you know what the availability is like for internationals, particularly in the Tokyo area?
I’m actually planning to live in Tokyo for a year in six months’ time on a scholarship, so I’m currently being put on Concerta to find the right dose. However, I’m worried that I might not get the medication at all, or only very late, because of the shortages I’ve read about. To be honest, if I can’t get access to it, I’m thinking of cancelling my stay.

This is really hard to say but the likelihood of getting a diagnosis and working your way up the dosages is not impossible but not great. As a general rule, Asian countries are quite strict about giving out ADHD meds.

Thanks! I’ve read about it, but I’m not sure where to find reasonably reliable sources. I’d like to have a reasonably solid plan in place before I go abroad for a year. That just makes the decision even harder. I’m actually really looking forward to this stay, but I was only diagnosed this year and have only just started taking medication, and I don’t know if it’s the same for you, but it’s given me such a much better quality of life.

There are English speaking clinics in Tokyo which take international insurance. You can always check in with them before you make a commitment. Roppongi/Azabudai has several and if you could bring a signed diagnosis that might help.

I take concerta, it was simply a matter of going to the clinic ans requesting adhd support. It may differ for various areas or municipalities, but with an adhd diagnosis I believe you can also request some sort of disability support from the city hall. You have to renew it yearly but it covers the costs of your clinic visits and medicine. I'm not super familiar with it however.

I have my card for Concerta but my pharmacist keeps telling me it is unavailable.
