ADHD Medication Shortage in Japan 2026: What Expats Need to Know

Japan has one of the most restrictive ADHD medication frameworks in the developed world, and as of April 2026, it just got harder. Concerta — one of only three ADHD drugs approved for adults in Japan — is in nationwide shortage. Clinics have stopped accepting new patients for it, and existing patients are rationed to two-week supplies. For the thousands of expats managing ADHD in Japan, this creates an urgent practical problem. Here is what you need to know.

What ADHD medications are available in Japan in 2026?

Japan’s standard protocol starts with non-stimulants first. You will likely be started on Strattera before a stimulant is considered — this is clinical standard, not discrimination against foreigners.

Is Concerta available in Japan in 2026?

No — not for new patients. Since late 2025, Concerta has been in nationwide shortage. Manufacturer Janssen Pharmaceutical initially said it would resolve in two months. Their March 2026 update to medical institutions revised that to “more than several months.” Most clinics have officially stopped prescribing Concerta to new patients. Existing registered patients are limited to 2-week supplies per visit.

Can I bring ADHD medication to Japan?

• Concerta and Vyvanse: Up to 30 days with original packaging and a doctor’s letter. More than 30 days requires an advance import certificate (yunyu kakunin-sho, 輸入確認書) from Japan’s Narcotics Control Department — apply at least 2 weeks before travel.
• Strattera and Intuniv: Up to 2-month supply. Keep your prescription and original packaging.
• Adderall: Completely prohibited. No exceptions for foreign prescriptions. Possession risks arrest and detention at customs — Japanese customs do not make humanitarian exceptions.

What can I do if I cannot get Concerta in Japan right now?

• Ask your clinic about switching to Strattera (atomoxetine, non-stimulant) as a bridge during the shortage.
• Ask specifically about Vyvanse — available at some clinics with a certified prescriber, not in shortage.
• If you are an existing Concerta patient, stay with your current clinic — existing registered patients have priority over new ones.
• Contact TELL Japan (telljp.com) for English-speaking mental health referrals.
• Use HIMAWARI (03-5285-8181) to locate English-friendly psychiatric clinics near you.

How do foreigners get ADHD diagnosis and medication in Japan?

Visit a psychiatrist (精神科, seishinka) or psychosomatic medicine clinic (心療内科). Bring your diagnosis history and prior medication list. Diagnosis requires 2+ appointments. National Health Insurance covers 70% of costs — roughly ¥3,000–5,000 per visit with NHI, or ¥10,000–28,000 at a private clinic. Stimulant prescriptions require a certified physician and a narcotic prescription card (麻薬処方せんカード, mayaku shohousen kaado). Prescription lengths in Japan: maximum 30 days per visit, often only 14 days for stimulants. Monthly clinic visits are required. Budget for this as part of your ongoing treatment cost.
