Japanese drugstores, or yakkyoku, can be daunting.  Even if you feel pretty good about your Japanese ability, names and descriptions of medicine can be highly technical and heavy on the kanji.  With shelves bursting with more products than you ever knew existed, finding the right medicine might seem like an impossible task.

And kampo-yaku, traditional herbal medicine, is viewed by most Japanese people (and doctors) as being interchangeable with Western medicine and is often stocked side-by-side. It’s a completely different scene from what you’d find in your average American drugstore.

Also, if you’re at a yakkyoku looking for Nyquil, you can stop searching, because medicine containing stimulants or codeine is illegal in Japan. You can’t bring them into the country, either.

If all this gives you a headache (on top of what you’re already suffering from!), don’t worry, this handy guide to Japanese OTC (over-the-counter) medicine will help you find what you need for those common ailments, and explain how to take them safely.

Trying to find what you need in a Japanese drugstore can be an overwhelming experience.

Just being in the store, which is usually stuffed to the brim with products, can be dizzying. Japanese drugstores have a way of exhausting your senses, especially when you don’t know exactly what you’re looking for.

And some medicine that is commonplace in an American drugstore, like Nyquil or Sudafed, is illegal, so you’ll have to find an alternative treatment for your colds and stuffy noses.

You could try kampoyaku, the traditional herbal medicine that some people (and doctors) swear by. It’s formally recognized by the Japanese Ministry of Health, and it could be just what you need.

Being sick is awful enough, so be prepared the next time it happens by keeping this guide handy. Self-medicating can be a breeze, even in Japan. You’ll feel genki again in no time!
