Can You Bring Ativan to Japan? The Lorazepam Limit Explained

You can bring Ativan to Japan. Lorazepam is a psychotropic on Japan's controlled-substance list, and the Narcotics Control Department (NCD) sets a no-certificate threshold for it: 90 mg total, non-injectable. If the lorazepam you're carrying, added up across your whole trip, comes to 90 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 90 mg. Ativan is typically prescribed in 0.5 mg, 1 mg, or 2 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 90 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.

Ativan (lorazepam) 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 lorazepam gets a milligram threshold instead of a flat no. The same NCD list sets thresholds for other benzodiazepines and sleep aids: alprazolam (Xanax) at 72 mg, clonazepam at 180 mg, triazolam at 15 mg, etizolam at 90 mg, and zolpidem (Ambien) at 300 mg — see bringing Xanax to Japan if you're carrying more than one of these.

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 lorazepam is injectable in any amount, or your supply runs past a one-month quantity. This isn't a same-week process — apply well ahead. For the full mechanics of the certificate system across all psychotropics, see Japan's psychotropic import limits.

If you're relocating rather than visiting, your carried supply of Ativan is a bridge, not a long-term plan. Pharmacists in Japan cannot fill a prescription written outside the country, so once you run low you need to see a doctor here. Lorazepam also falls under the categories excluded from Japan's refill-prescription system, so each renewal means a fresh consultation rather than a repeat visit to the pharmacy alone. Psychiatrists in Japan are medical doctors who prescribe directly and accept insurance, but the exact medication path — whether that means staying on a benzodiazepine or discussing alternatives — is a decision to make with that doctor, not a website.

The finder can help you locate a pharmacy with verified English support once you have a prescription to fill, and the health guide has the fuller picture of import rules if you're weighing what to bring against what to establish locally.
