> And yet, it's completely illegal for me to travel to Japan for even a day with my ADHD medication. I could be carrying my script, a letter from my doctor, and have literally only a single days supply, and I'd be risking a very serious prison sentence.
Ok, I Googled about this.
English language policy from Japan gov't: https://www.mhlw.go.jp/english/policy/health-medical/pharmac...
Scary US embassy page: https://jp.usembassy.gov/services/importing-medication/
Still, that page provides an email address. Try it with your medicine, and see what happens.
More from a US-based non-profit: "Japan Focus: ADHD and Traveling with Medication" -> https://www.miusa.org/resource/tip-sheets/japanfocus/
They recommend to ask in advance. If denied, skip it for the trip (I know how people will react on HN to that suggestion!) or carry an allowed alternative.
Your last paragraph feels like it was lifted from a non-profit that advocates for ADHD disability rights. It is incredibly specific. Also, I'm really tired of repeating myself on HN: Saying "Europe" doesn't say much. Europe is huge. It is (at least) 44 countries and 27 belong to the EU. There are huge differences between each country. Do you really expect us to believe that in the Nordics that "ADHD is still close to non-recognised"? I find it hard to believe.
