# Can I use a hair dryer bought in Japan back home?

> It depends on the voltage. As of October 2026, hair dryers in Japanese stores come in two types: domestic models labeled “AC100V” will burn out on 220V power, while global-voltage models labeled “100–240V” or with a voltage switch (海外対応) can be used abroad; set switchable models to the right setting before first use. Japanese dryers have Type A two-flat-pin plugs and no battery, so they can go in carry-on or checked baggage.

## The 30-second check

Look at the rating label on the dryer (usually near the handle or power cord) or on the back of the box:

| Label | Usable abroad? | How to use |
| --- | --- | --- |
| 定格電圧 AC100V | No | Japan only |
| AC100–240V | Yes | Adjusts automatically; just plug in |
| AC100–120V / 200–240V (電圧切替) | Yes | Before first use on 220V power, set the switch to the 200–240V position |
| 海外対応 / 海外兼用 | Yes | Still check the exact voltage range |

Within the same brand and series, stores often carry both domestic and overseas-compatible models. They look similar and differ only in model number or packaging, so always check the voltage.

Check whether it works in your country in our [compatibility table](/en/tools/compat/).

## What if the switch is on the wrong setting?

- Left on 100V and plugged into 220V: it overheats instantly and may burn out or even catch fire.
- Left on 220V and plugged into 100V in Japan: weak airflow and low heat, but usually no damage.

So check the switch position before plugging it in at home for the first time.

## Can I use a domestic model with a transformer?

Not recommended. Hair dryers usually draw around 1,000–1,500W (check the rating label), so you would need a step-down transformer rated at more than twice that. It's big and heavy, running it at full load for long periods creates heat risks, and the transformer may cost more than you save.

## Plugs and other notes

- **Plug**: Japanese hair dryers use Type A two-flat-pin plugs. Whether they fit your sockets depends on your country. See [Do I need a plug adapter?](/en/q/plug-adapter-china/)
- **Frequency**: Most work on both 50/60Hz. See [Does 50Hz vs. 60Hz matter?](/en/q/50hz-60hz/)
- **Flying**: No battery, so carry-on or checked are both fine. Check large boxes.
- **Warranty**: Hair dryers bought in Japan generally aren't covered by warranty outside Japan. See [warranty on Japanese appliances](/en/q/warranty-japan-appliance/).

For choosing styles, airflow, and features, see the [hair dryer buying guide](/en/q/hair-dryer-buying-guide/). You can check the voltage of specific models on the [hair dryer category page](/en/c/hair-dryer/) or with the [compatibility checker](/en/tools/compat/).
