HRT in Japan: How Menopause Treatment Actually Works Here

Hormone replacement therapy in Japan is accessed through doctors, the same way most prescription-only treatment works here - for menopausal HRT specifically, that means a gynecologist. There's no over-the-counter version: a Japanese prescription (shohosen {jp:処方箋}) comes first, filled at a dispensing pharmacy second. If you're bringing patches with you in the meantime, they may fall under the more generous external-use item allowance rather than the standard prescription-drug allowance - it depends on how your specific medication is classified, which is worth confirming before you pack. The rest of this page covers both halves: the import math for what you're carrying, and how to find a gynecologist once you're here.

Japan operates on 医薬分業 (iyaku bungyo) - prescribing and dispensing are kept separate by law. A doctor writes the shohosen; only a licensed dispensing pharmacy fills it, and any dispensing pharmacy in the country can fill a valid Japanese prescription, not just the one attached to the clinic. There's no gatekeeping GP standing between you and a specialist, so you can go straight to a gynecology clinic. A prescription written outside Japan cannot be filled here, no exceptions, so an existing prescription from home doesn't transfer - you'll need a Japanese gynecologist to write a local one. A standard prescription is valid for 4 days including the issue day, weekends and holidays counted, so fill it promptly.

MHLW's personal-import rules set different allowances by form. External-use items are allowed up to 24 units per item without any certificate, a more generous bucket than the 1-month cap on oral prescription drugs. Whether a hormone patch counts as an external-use item or falls under the prescription-drug allowance instead isn't something to assume - confirm the classification for your specific medication, for instance when applying through MHLW's import certificate process, rather than relying on the more favorable reading. Other forms of hormone therapy, such as tablets, follow the standard prescription-drug rule. Either way, carry a copy of your prescription and a doctor's letter with the medication, even comfortably inside the allowance - customs can ask, and having it on hand settles the question.

Brand names for hormone therapy vary by country, and the brand you know may mean nothing to a customs officer or a Japanese pharmacist. What travels reliably is the International Nonproprietary Name (INN) - the generic active-ingredient name, such as estradiol. A doctor's letter stating the INN alongside the brand name, dose, and form is far more useful at the airport, and it's the same information a Japanese gynecologist will want if you're moving to a local prescription.

For the wider system this fits into, see the TokyoPharmacies health guide, and if you're relocating rather than visiting, the moving to Japan guide covers setup like ward registration and insurance enrollment.
