Under the Stimulants Control Act and the Cannabis / Psychotropics Control Act regimes, many ingredients that are legal or prescription-available in other countries (amphetamines, certain methamphetamine derivatives, some CBD / opioid products) are strictly prohibited in Japan, and a prescription does not automatically constitute lawful grounds for import.

※ The MHLW NCD application-guidance page states outright that amphetamine (Adderall's active ingredient) is a stimulant (覚せい剤)-regulated substance and cannot be imported; Japan's line is that a prescription does not constitute lawful grounds for import (the same ingredient is permit_required in AU but prohibited in JP — a typical case of attribute-level per-country divergence).

Most permits take weeks to process and must be applied for in advance. The ones you remember the day before departure are usually too late.
Amounts follow the current publication of Japan regulators; we never show unverified numbers on a page. Decision-grade ranges appear in the “penalty exposure” section of the full dossier.
One call answers “do you take it” but never “does the country allow it”. Only after all four questions do you have the complete answer. Note the agent's ID and the time of each answer.
“I want to send BPC-157 injectable peptide (standard retail packaging) from [origin country] to Japan via carry-on baggage. Does your network accept it?”
Why ask it this way: Ask acceptance first, never compliance — agents are responsible for what they carry, and a compliance question only earns a disclaimer.
“If you accept it: exactly how must the waybill describe the contents? What labels or enclosed documents do you require? Please give me the specific wording.”
Why ask it this way: A waybill description that mismatches the contents is the number-one trigger for inspection. You need exact wording, not “be more detailed”.
“If you don't: which prohibited-items clause applies? Would a change in [processing / packaging / quantity] make it acceptable? Do any of your other services carry it?”
Why ask it this way: Turn “no” into “yes, under condition X” — this question routinely surfaces routes the carrier would never volunteer.
“Is your refusal based on Japan import restrictions, or on your own policy? Can you give me the written link or clause number?”
Why ask it this way: This separates the two switches. Carrier policy can be switched; import law cannot — the answer decides your next move.

⚠️ Print this page alone. The card is designed to be shown by itself — the officer does not need our verdicts or sources.

A carrier answers “do we take this on our network today”; biosecurity and customs authorities in Japan answers “does this country let it in”. Two independent questions — no single institution answers both, and seized parcels almost always trace back to asking only one. This site solves the two switches together and shows you what change makes it work.
