Japanese hair dryers are a popular choice for their quality and innovative functions.
Many travelers consider buying one during their stay in Japan.
But keep in mind that Japan uses 100V, which is different from most other countries.
This guide explains what you need to know about voltage, dual voltage models, and the best brands to look for.
In this guide, I’ll explain the key things to watch out for when choosing a hair dryer in Japan, and introduce some of the most popular Japanese brand
Why Voltage Matters for Hair Dryers in Japan
Japan runs on 100V, while many countries use 120V, 220V, or even 240V.
This difference may look small, but for appliances like hair dryers it makes a big impact.
A dryer built only for Japan may not heat properly overseas, and one from abroad may not work safely in Japan.
As shown in the chart above, voltage standards vary by country.
This is why dual voltage hair dryers are convenient for travelers who plan to use one in different regions.
Panasonic also notes this on its official site, warning users to always check the voltage before purchase.
Buying a Hair Dryer in Japan: What Travelers Should Know
Japanese hair dryers often come with advanced features, such as quick-dry modes and ion or nanoe technology.
You’ll see them everywhere — from big electronics stores to local drugstores — and the price range goes from very affordable to pretty high-end.
One thing to keep in mind: most of them are made for Japan’s 100V system.
So if you’re thinking of bringing one home, check the label and look for a dual voltage model just to be safe.
Dual Voltage Hair Dryers in Japan: How to Check Compatibility
If you plan to use a dryer in Japan and back home, it’s easier to go with a dual voltage model.
They usually cover both 100–120V and 220–240V, so you don’t have to worry about compatibility.
How to Know if Your Hair Dryer Is Dual Voltage
Check the label on the handle or plug.
- If it says “100–240V”, the dryer is dual voltage and safe to use abroad.
- If it says “100V”, it is for Japan use only.
Plug Types and Voltage by Country
Japan uses Type A plugs with 100V.
Other countries may use different shapes and voltages, so a plug adapter is often needed.
Remember, an adapter only changes the plug shape — not the voltag
| Country/Region | Voltage (V) | Plug Type |
|---|---|---|
| United States / Canada | 120 | A, B |
| Japan | 100 | A, B |
| South Korea | 220 | C, F |
| China | 220 | A, I |
| Hong Kong | 220 | G, D |
| Taiwan | 110 | A, B |
| Malaysia | 230 | A, C, G, M |
| Singapore | 230 | C, G, M |
| Australia | 240 | I |
| United Kingdom | 230 | G |
| Germany/ Spain | 230 | C, F |
Can You Use a Japanese Hair Dryer Abroad?
Most Japanese hair dryers only work on 100V, which means they won’t run properly in countries with 220–240V.
If you really want to use one abroad, go for a dual voltage model.
Can You Use Your Hair Dryer in Japan?
Japan runs on 100V.
If your dryer is made for 220–240V only, it will not work properly in Japan.
A dual voltage model (100–240V) is fine — just check the label before you plug it in.
That said, most hotels and even many Airbnbs in Japan provide a dryer, so you probably won’t need to bring one at all.
Popular Japanese Brands with Dual Voltage Hair Dryers
Before looking at the main brands, keep in mind that dual voltage dryers are limited in Japan.
Most models are made for 100V, so always check the label if you plan to use it outside Japan.

Summary: Voltage Compatibility for Japanese Hair Dryers
Japan runs on 100V, which is different from most countries.
If your dryer is only for 220–240V, it won’t work here — but a dual voltage model (100–240V) will.
Some Japanese brands, like Panasonic, Koizumi, and Tescom, do have dual voltage options, so it’s worth checking if you’re thinking of buying one
If you plan to buy a dryer during your trip, these brands offer reliable options worth considering.
