Yes, you can bring some ADHD medications to Japan—but others (like Adderall) are completely banned, even with a prescription. Many travelers only discover these rules at the airport—when it’s already too late.

👉 The good news: Most travelers can bring their medication legally—if they follow the correct steps before arrival. This guide explains exactly what’s allowed, what’s banned, and how to avoid problems at Japanese customs.

Quick Answer (2026)
Amphetamines are strictly illegal. Do not bring.
Apply for Yunyu Kakuninsho before arrival.
Limit: 2.16g active ingredient without permit.
What Most Travelers Get Wrong
- Thinking a prescription makes all medications legal (it doesn’t in Japan)
- Assuming airport security rules = customs laws
- Not checking the active ingredient
- Bringing extra medication “just in case”
- Forgetting to apply for permits in advance
Always verify the active ingredient, not the brand name. This is where most travelers make mistakes.
1. Banned Medications (Do NOT Bring These)
Medications containing amphetamine or methamphetamine salts are strictly prohibited under Japanese law.
Common examples:
- Adderall
- Dexedrine
👉 There are NO exceptions—even with a valid prescription.
What Happens If You Bring a Banned Medication?
- Medication will be confiscated
- You may be detained for questioning
- In serious cases, legal penalties can apply
👉 This is why checking your medication before your trip is critical.
2. Restricted Medications (Rules You Must Follow)
Some ADHD medications are allowed—but only under strict conditions.
Vyvanse (Lisdexamfetamine)
- Classified as a “Stimulant Raw Material”
- Permit required in ALL cases (even small amounts)
👉 You must apply for an import certificate before entering Japan.
Concerta & Ritalin (Methylphenidate)
These are classified as psychotropic medications in Japan.
- ≤ 2.16 g total active ingredient → No permit needed
- > 2.16 g → Permit required
How Much Is 2.16 g?
This depends on your dose.
Example:
- 36 mg tablets × 30 days = 1080 mg (1.08 g) → ✅ Allowed
- Higher doses or longer trips may exceed the limit
👉 Always carry your prescription and original labeled bottle.
Japan’s medication laws are strict, but very clear. Most problems happen when travelers assume their home prescription automatically applies internationally. If you’re unsure, it’s safer to apply for a permit.
3. How to Apply for an Import Permit (Step-by-Step)
If you need a permit (for Vyvanse or larger quantities):
Step 1: Start early
Apply at least 3–4 weeks before your trip
Step 2: Contact Japanese authorities
Email the Ministry of Health, Labour and Welfare (MHLW)
📝 Official Application Resource
You can find the official application forms and latest requirements on the
Ministry of Health, Labour and Welfare website.Step 3: Submit documents
You’ll typically need:
- Doctor’s letter (diagnosis + necessity)
- Medication details (name, dose, quantity)
- Completed application form
- Flight itinerary
Step 4: Receive your certificate
You’ll get a digital permit—print it and bring it with you
4. What Happens at Japanese Customs?
When you arrive (Narita, Haneda, Kansai, etc.):
- Declare your medication on your customs form
- Go through the Red Channel (Goods to Declare)
- Show:
- Original medication bottles
- Prescription
- Import certificate (if required)
- The officer may verify your medication quantity
👉 If everything is correct, you’ll be allowed through without issues. Always double-check requirements before your trip, as rules can change.
Simple Checklist Before You Fly
- Check if your medication is banned or restricted
- Verify the active ingredient
- Calculate your total dosage
- Apply for permit (if needed)
- Keep meds in original packaging
- Declare everything at customs
Should You Be Worried?
For most travelers:
👉 No—if you prepare properly
You’re at low risk of issues if:
- Your medication is allowed
- You stay within limits
- You bring proper documentation
You’re at high risk if:
- You bring banned substances (like Adderall)
- You don’t check requirements in advance
Final Thoughts
Japan has strict medication laws—but they are clear and manageable if you prepare ahead of time.
By checking your medication, understanding the rules, and bringing proper documentation, you can travel confidently without unnecessary stress.
