Insect Repellent & Bug Spray in Japan - 7 Must-Haves for Humid Summer Nights
| Nationwide Shopping Drugstore | 2020.07.13 |
With the warm humidity of Japan's summer comes an inevitable wave of bugs, so stock up and keep the insects at bay!
Choosing the Right Bug Spray
It's summer, which means it's time to avoid three things: heatstroke, sunburn, and bug bites. Whether you're escaping Japan's bright summer sun with a hike in the woods or cooling down with a dip in the ocean, though, the bugs will follow! So it's good to know just what options there are in Japan when it comes to keeping the insects away. There are sprays for your skin, sprays for the room, coils, and vaporizers as well, made with a few common repellents.
Most of the bug sprays in Japan use just a handful of active ingredients, and like much of the world, DEET is perhaps the most common. It's been in use since the 40s, confusing mosquitos away instead of killing them. Of course, some people try to avoid DEET because incorrect application can indeed lead to health issues - everything from simple irritated skin to dizziness, and worse problems in rare cases. But its effectiveness is still just about as good as it gets, which means it's still popular.
Picaridin (a common name for Icaridin) is a more recent innovation in bug repellent, but it's quickly gaining ground with growing evidence showing its effectiveness and lack of skin irritation. While it's been around for 15 years in places like the US, Japan only approved it 10 years later, making it still something of a novelty. The chemical is actually part of the same family as one that gives black pepper its kick!
Otherwise, a handful of natural repellents are used in Japan, including ingredients like peppermint oil, pyrethrum (made from chrysanthemums), and oil of lemon eucalyptus. Evidence for these ingredients variesーsome are naturally quite effective but for limited periods, while others are stronger but irritating for children under three.

Johnson Skinguard Aqua
➡ Conveniently Portable
Active Ingredient: 5% DEET
Portability is undeniably important, especially when it's a product you may need to reapply during the day (or forget to put on before you head out). The 50ml version of Johnson Skinguard Aqua is about the length of a smartphone, and since it's a non-aerosol spray under 100ml, it can even be left in your carry-on bag when boarding a plane within Japan. While the main repellent ingredient is DEET, it also contains aloe and mint, making the formula non-sticky and also refreshing in the summer.
