Resolving the confusion around medication import regulations
Anyone planning to bring medication to Japan encounters contradictory information from seemingly official sources. This confusion exists because two separate government agencies—the Ministry of Health and Tokyo Customs—have different rules. Understanding this distinction is the key to navigating the system with confidence.
Travel forums, embassy websites, and even authoritative sources contradict each other on basic questions like which medications require customs declaration. Travelers arrive at Japanese airports uncertain whether their medications will be confiscated or which customs channel to use.
This guide was created to resolve that confusion by making the crucial distinction between agencies clear.
The confusion stems from a fundamental misunderstanding: medication imports involve two distinct government entities with separate jurisdictions and different requirements.
The Ministry of Health, Labour and Welfare (MHLW) controls which medications can legally enter Japan. The Tokyo Customs controls what happens at the border, including declaration requirements and inspection procedures.
Same medication, different requirements: A medication can be "permitted" by MHLW while simultaneously requiring "Red Channel declaration" by Customs. This dual system explains why travel guidance often seems contradictory.
MHLW Status: Permitted up to 180mg without advance permit
Customs Status: Must be declared at Red Channel (psychotropic substance)
Result: Legal to import, but requires specific border procedure
This fundamental distinction explains why medication import guidance often appears contradictory - different agencies, different rules, different procedures.
Every piece of regulatory information on this site goes through our systematic verification process:
1. Official MHLW documentation - Primary source review of substance classifications and permit requirements
2. Customs authority confirmation - Direct correspondence with Tokyo Customs regarding border procedures
3. Embassy guidance cross-reference - Secondary verification through diplomatic sources

We are not medical professionals - we are information researchers who systematically track and translate official Japanese sources. When sources conflict, we contact authorities directly for clarification.
We maintain a straightforward philosophy: transparency is always the best policy. When someone writes, "I brought my controlled medication in without declaring it and had no problems," they are describing a successful gamble, not a rule.
The customs officers of Japan are professionals. A proactive, honest declaration, supported by proper documentation, is not an admission of wrongdoing—it is a sign of respect for the country you are visiting. It is the most reliable path to being processed efficiently, leaving you free to begin your journey with peace of mind.
By conducting the necessary research on your behalf, we aim to replace uncertainty with clarity, allowing you to focus on the true purpose of your travels.
This website provides informational guidance only and is not a substitute for professional medical or legal advice. While we strive for accuracy through direct correspondence with official sources, medication import regulations can change, and individual circumstances may vary. Always verify current requirements with official Japanese government sources and consult with healthcare professionals regarding your specific medical needs.
