Root Cause
Japan bans or restricts many medications legal elsewhere. Stimulants such as Adderall and Vyvanse (amphetamines) are strictly prohibited even with a prescription, and some cold/allergy medicines with pseudoephedrine or codeine are restricted. Bringing more than about one month's supply, or any controlled item, without a Yakkan Shoumei import certificate can lead to seizure or detention.
genericWorkarounds
-
85% success Check the prohibited/controlled list and apply for a Yakkan Shoumei import certificate before travel for larger or controlled supplies.
Confirm your medication on the MHLW list; for prohibited drugs ask your doctor about a legal alternative; for large/controlled supplies apply for a Yakkan Shoumei by email well before departure and carry the approval.

Dead Ends
Common approaches that don't work:
-
Pack your usual ADHD or strong cold medication for Japan assuming a prescription makes it legal
80% fail
Amphetamine-based stimulants (Adderall, Vyvanse) are prohibited imports regardless of a foreign prescription; travelers have been detained for bringing them. Pseudoephedrine above the limit is also restricted.
-
Bring more than one month's supply of prescription medicine without a Yakkan Shoumei
60% fail
Importing over roughly one month's supply, or controlled/injectable items beyond limits, requires a Yakkan Shoumei certificate obtained in advance; without it customs can confiscate or detain.
