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

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:

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.

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?
• Frequency: Most work on both 50/60Hz. See Does 50Hz vs. 60Hz matter?
• 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.

For choosing styles, airflow, and features, see the hair dryer buying guide. You can check the voltage of specific models on the hair dryer category page or with the compatibility checker.
