In a dry Japanese winter, a scratchy throat is common. Drugstores and konbini sell throat candy, troches, sprays and gargles, plus the famous 龍角散. Some look like sweets but are medicines.
This guide is only about the throat. It explains the labels and 7 widely sold throat products with prices on 10 November 2026. For fever, runny nose and cold tablets, see our Japanese cold medicine guide.
We did not test these products, and there is no ranking. Medicine facts come only from the makers’ pages and the leaflets published by Japan’s drug agency, PMDA. If you have a high fever, severe pain, trouble swallowing, trouble breathing, or your throat is not better after a few days, see a doctor.
📌 What you will learn
In a hurry? Japanese drugstores sell throat products as candy のど飴, troches トローチ, powder like 龍角散, sprays のどスプレー, plus gargles うがい薬. Check the small label first: 食品 is food, 医薬部外品 is a quasi-drug, while 第2類医薬品 / 第3類医薬品 means a medicine. For medicines, check the age limit, read the leaflet, 添付文書, and ask the pharmacist, 薬剤師. Iodine sprays, gargles have extra cautions for thyroid problems.

The labels on the box
Look for the category, printed small on the box, plus the form.
Food, quasi-drug, medicine
| Label | What it is | What it means for you |
|---|---|---|
| 食品, キャンディ, のど飴 with no other label | Food, candy | Ordinary candy, often with herbs or menthol. No approved medical effect, no dose |
| 医薬部外品, 指定医薬部外品 | Quasi-drug | A mild action under Japanese law. The box lists an active ingredient, such as CPC, セチルピリジニウム塩化物, in some drops |
| 第3類医薬品 | OTC medicine, class 3 | The lowest risk class. It still has a dose, an age limit, cautions |
| 第2類医薬品, 指定第2類医薬品 | OTC medicine, class 2 | A higher risk class. 指定第2類 means it needs special care. Ask the pharmacist (薬剤師) first |
| 第1類医薬品 | OTC medicine, class 1 | Needs the most care. None here is class 1 |
※ Classes from the Ministry of Health, Labour and Welfare (厚生労働省) definitions; quasi-drugs from the Japanese law on medicines, article 2 (e-Gov).
The same brand can sit in different categories. Asada Ame sells 固形浅田飴 as a medicine, 浅田飴ガードドロップ with CPC as a quasi-drug, plus のど飴 as food.

Before you buy, tax-free, flying home
✅ Check before you buy
- Category: 食品 is candy. 医薬部外品 is a quasi-drug. 第2類, 第3類 mean medicine: read the leaflet
- Age: check 15才以上 and the lowest age on the box. Keep medicine drops away from children
- Iodine: ヨウ素, ポビドンヨード. Ask first if you have a thyroid problem. The のどぬ〜る spray is not for pregnancy
- Other medicines: if you also take cold medicine, show both boxes to the pharmacist
- How to use: troches dissolve slowly, granules need no water, gargles must be diluted
- Allergy: read 成分 for anything you react to. Ask the pharmacist if unsure
- See a doctor: high fever, severe pain, trouble swallowing, trouble breathing, no better after 5 to 6 days
Dry air makes a scratchy throat worse. For the room, see our Japanese humidifier guide. For a warm rest at night, see our steam eye mask guide.
Is it halal? Is it vegan?
None of the maker pages we checked says a product is halal or vegan, so treat this as not confirmed. Read the ingredient list and contact the maker.
Can I buy throat medicine tax-free?
Since 1 November 2026, Japan uses a refund method. You pay the full price with tax, and you get the tax back after customs confirms the goods when you leave Japan. You need to spend at least ¥5,000 before tax in one shop on one day, show your passport within 90 days of buying, and do it before you check in your bags.
The Japan Tourism Agency (観光庁) says consumables such as food, drinks, cosmetics cannot get the refund if used in Japan. If one item on a receipt cannot be confirmed, nothing on that receipt is refunded. Buy what you will use now on a separate receipt. Read more in our Japan tax-free shopping guide.
Sprays, gargles in hand luggage
Japan’s Ministry of Land, Infrastructure, Transport and Tourism (国土交通省) says that on international flights, liquids, aerosols and gels must be in containers of 100 mL at most, inside one clear zip bag of up to 1 L. Its list names mouthwash plus liquid medicines. The 15 mL spray fits; put a 120 mL gargle in your checked bag. Medicines needed on board may go beyond the limit if you tell the security officer. Rules differ by airline and country, so check with your airline.
Frequently asked questions
Is のど飴 the same as throat medicine?
No. Most のど飴 are food, like 龍角散ののどすっきり飴. Some drops look like candy but are medicines, such as 固形浅田飴クールS, a 指定第2類医薬品. Check the label on the box.
Can children use these?
Only as the box says. Lowest ages: 3 years for 龍角散ダイレクトスティック, 5 for the troche plus 固形浅田飴, 2 for のどぬ〜るスプレー. An adult should watch.
I am pregnant. What can I use?
Ask a doctor or pharmacist first. The のどぬ〜る spray leaflet says not to use it in pregnancy or while breastfeeding. Asada Ame says pregnant women should ask before taking 固形浅田飴, while its FAQ says the AZ gargle can be used, without swallowing it.
Will they make me sleepy?
Ryukakusan says 龍角散ダイレクト has no ingredient that makes you sleepy. The other pages we checked do not mention drowsiness. Read the leaflet, and ask the pharmacist if you will drive.
Iodine or azulene gargle?
イソジンうがい薬 uses povidone-iodine. Its leaflet says to ask first if you have a thyroid problem. 浅田飴AZうがい薬 uses azulene, with no iodine. A pharmacist can help you choose.
The short version
First check the label: 食品 is candy, 医薬部外品 is a quasi-drug, while 第2類 / 第3類医薬品 is a medicine with a dose plus an age limit. For a herbal medicine without water, there is 龍角散ダイレクトスティック, or the troche 龍角散ダイレクト トローチ マンゴーR. 固形浅田飴クールS is a class 2 medicine. 龍角散ののどすっきり飴 is candy. For sprays plus gargles, のどぬ〜るスプレー plus イソジンうがい薬 contain iodine, while 浅田飴AZうがい薬 uses azulene. Read the leaflet, ask the pharmacist (薬剤師), and see a doctor if your symptoms are severe or last.
