Can You Bring Xanax to Japan? The Alprazolam Limit Explained

You can bring Xanax to Japan. Alprazolam is a psychotropic on Japan's controlled-substance list, and the Narcotics Control Department (NCD) sets a no-certificate threshold for it: 72 mg total, non-injectable. If the alprazolam you're carrying, added up across your whole trip, comes to 72 mg or less, pack it in your carry-on and go. Go over that number, or bring it as an injectable, and you need an import certificate arranged in advance.

The threshold is a total milligram amount for the whole trip, so you need to multiply your prescribed dose by how many days' supply you're carrying, then compare that to 72 mg. Xanax is typically prescribed in 0.25 mg, 0.5 mg, or 1 mg tablets, taken once to a few times a day, so the math varies a lot person to person.

Run your own numbers the same way: daily mg times days you'll carry medication for. If your figure lands at or under 72 mg, you're inside the exemption; if it's close, round up rather than down. This also interacts with the general rule that prescription drugs are allowed up to a one-month supply without a certificate — a high daily dose can put you over the mg threshold well before you hit a month's worth of pills.

Xanax (alprazolam) belongs to the benzodiazepine class, and Japan regulates benzodiazepines as psychotropics rather than outright prohibited substances — unlike stimulants such as amphetamine, banned even with a foreign prescription. That distinction is why alprazolam gets a milligram threshold instead of a flat no. The same NCD list sets thresholds for other benzodiazepines and sleep aids: clonazepam at 180 mg, triazolam at 15 mg, lorazepam at 90 mg, etizolam at 90 mg, and zolpidem (Ambien) at 300 mg — see bringing Ambien to Japan if that applies to you too.

Going over the threshold doesn't mean you can't bring your medication — it means you need a Yunyu Kakunin-sho (輸入確認書), still widely called by its older name Yakkan Shoumei (薬監証明), issued by MHLW. The same certificate is required if your alprazolam is injectable in any amount, or your supply runs past a one-month quantity. This isn't a same-week process — apply well ahead.

If your prescription runs out in Japan, pharmacists cannot fill a foreign script — you'd need to see a doctor locally, and alprazolam is excluded from the refill-prescription system, so each visit means a fresh consultation.
