How to Read Japanese Medicine Labels and Instructions
The terms on a Japanese prescription bag and drug-information sheet, decoded, so you know what to take and when.
You leave the pharmacy with a paper bag of tablets and a sheet covered in kanji, and none of it tells you in English whether to take this before or after a meal, or how many times a day. Japanese medicine instructions follow a small, fixed set of terms once you know them - this is what 食後, 食前, 頓服, and the rest actually mean, plus what to do when a term isn't on this list.
The short answer
How to read a Japanese medicine labelJapanese medicine instructions use a small, repeating set of terms, so once you recognize them, most labels read the same way every time. The label or drug-information sheet gives you the dosage instructions (用法・用量): timing - 食後 after meals, 食前 before meals, 食間 between meals, 就寝前 before bed - plus frequency, written like 1日3回 (three times a day), and form, whether it's a 錠 (tablet) or カプセル (capsule). A separate term, 頓服, means take as needed rather than on a schedule. If anything on your specific medicine is unclear, ask the pharmacist before you leave - that's what the counseling counter is for.
The terms that actually appear on labels
Timing, frequency, and form, in one tableThese are the terms you'll see repeated across nearly every Japanese prescription and OTC label. Learn this set and you can read most instructions without a dictionary.
| Japanese | Reading | Meaning |
|---|---|---|
| 用法・用量 | yōhō / yōryō | Dosage instructions - how and how much to take |
| 食後 | shokugo | After meals |
| 食前 | shokuzen | Before meals |
| 食間 | shokukan | Between meals (not literally mid-meal) |
| 就寝前 | shūshinmae | Before bed |
| 1日3回 | ichinichi san-kai | Three times a day (the number before 回 is how many times) |
| 錠 | jō | Tablet |
| カプセル | kapuseru | Capsule |
| 内服薬 | naifukuyaku | Oral medicine (taken by mouth) |
| 外用薬 | gaiyōyaku | External use (applied to the skin, not swallowed) |
| 頓服 | tonpuku | Take as needed, not on a fixed schedule |
Why meal timing is on nearly every label
It's about absorption and stomach tolerance, not habitMeal-timing instructions show up on almost every dispensed medicine in Japan, prescription or OTC, because timing affects how a drug is absorbed or how well your stomach tolerates it. That's a decision your doctor or the dispensing pharmacist already made for the specific medicine you were given - the label reports that decision, not a general habit. If you genuinely can't take a dose at the specified time relative to a meal, ask the pharmacist rather than guessing, since some medicines are timed for absorption and others for stomach protection, and the right adjustment differs.
The drug-information sheet you're handed with every fill
More detail than the label itselfEvery dispensed medicine in Japan comes with a printed drug-information sheet, in addition to whatever's on the bag or bottle. It typically repeats the dosage instructions in fuller sentence form, plus what the medicine is for, common side effects, and storage notes. If the label's shorthand is confusing, the sheet is usually clearer - keep it, since it's also useful if you see a different doctor later or need to check something after leaving the pharmacy.
- The drug-information sheet for each medicine, not just the label on the bag
- Your お薬手帳 (medication notebook), if you keep one - see the okusuri techo guide
- A note of any term you had to ask the pharmacist to explain, for next time
What to do when a label isn't clear
In order, from fastest to most thorough- Check the drug-information sheet first.
It usually spells out in fuller sentences what the shorthand on the label is abbreviating.
- Match unfamiliar characters against the term table above.
Most Japanese medicine instructions are built from this same small set of terms, combined in different orders.
- Use a translation app's camera mode as a fallback, not a first resort.
It's useful for general text, but it can misread dosage numbers or medical shorthand - don't rely on it alone for how much or how often to take something.
- Ask the pharmacist directly before you leave the counter.
A few key phrases go a long way here - see the pharmacy phrases guide for exactly what to say.
- Look for a pharmacy with verified English support if language is the real barrier.
Use the pharmacy finder to filter for English-language support before you go, rather than working it out after you're already at the counter.
None of this replaces the pharmacist's own explanation - Japanese pharmacies do in-person counseling with most dispensed medicines specifically so you leave knowing how to take them. If you're still setting up care in Japan more broadly, the health guide and moving to Japan guide cover the wider system this label is part of.
Frequently asked questions
Quick answers to the questions people actually searchWhat does shokugo mean on a Japanese medicine label?
食後 (shokugo) means "after a meal." It's the most common timing instruction on Japanese prescriptions and tells you to take the dose after eating rather than on an empty stomach - if you need the exact window for a specific medicine, check the drug-information sheet or ask the pharmacist.
How do I know how many times a day to take a Japanese medicine?
Look for a phrase like 1日3回 (ichinichi san-kai), which means "three times a day." The number before 日 is per-day frequency; the number before 回 is how many times. This is usually printed right next to the meal-timing term on the label or drug-information sheet.
What's the difference between shokuzen and shokukan?
食前 (shokuzen) means before a meal, and 食間 (shokukan) means between meals - not literally in the middle of eating. They're easy to confuse because both use the character for meal, so check the second character carefully or ask the pharmacist to confirm.
What does tonpuku mean on a Japanese prescription?
頓服 (tonpuku) means take as needed, rather than on a fixed schedule - typically for symptoms like pain or fever rather than a regular course. If a label says 頓服, check the sheet for a maximum frequency (such as a minimum number of hours between doses) rather than assuming you can take it whenever.
Can I just use a translation app to read a Japanese medicine label?
A translation app's camera mode is a reasonable fallback for unfamiliar text, but it can misread dosage numbers or medical shorthand. For anything about how much to take or how often, confirm with the pharmacist directly or ask them to check the drug-information sheet with you before you leave the counter.
