Dyson Supersonic Travel in Japan: is 100V supported?

The US Supersonic Travel HD19 has an unresolved Japan answer. Dyson’s owner page lists both 110–240V and 100–240V; do not treat one range as confirmed for your exact dryer. Japan uses a nominal 100V supply, so the appliance’s documented minimum voltage matters. Japan electrical reference ↗

Check another tool for Japan ↗

Each tool still needs its own exact-model and outlet checks. A suitable local or hotel dryer is another option while your Dyson’s rating remains unresolved.

Two ranges on the same owner page

Dyson’s US HD19 owner page gives 110-240V in its travel section and 100-240V in its international-travel FAQ. We have not established which statement applies to the exact regional appliance. At Japan’s 100V supply, these ranges lead to different voltage checks. Dyson owner page, travel section and FAQ ↗

Dyson’s US Prussian Blue/Rich Copper product specifications also list 100-240V. We still have not resolved the owner-page inconsistency or completed the exact-model electrical checks. Dyson product specifications ↗

What to confirm before packing

Find your model code and electrical label, including voltage and frequency. If the label and instructions do not clearly agree, ask Dyson to confirm the permitted rating for that exact regional model. Help reading your label ↗

You can make the question specific:

My model code is [code] and its label reads [rating]. Does this exact version support 100V at my destination’s frequency? Your owner page lists two different minimum voltages.

Japan has both 50Hz and 60Hz regions. Confirm the frequency for your destination as well as the voltage.

An adapter is a separate check

Dyson’s page recommends an adapter rated for 1300W across its stated voltage range. That advice does not resolve the conflicting appliance ratings or establish an adapter suitable for your actual outlet. Dyson adapter advice ↗

Does a 100W USB adapter have enough power?

The USB charging rating does not tell you the AC socket’s capacity. A dryer with a mains plug uses the AC socket, so look for that socket’s separate load rating at your destination voltage.

For example, Ceptics lists its UP-100KU-WC retractable USB-C cable at 100W and its universal AC socket at a maximum of 10A. Those ratings describe different outputs, and watts and amps are different units. The 100W headline alone neither rules out nor confirms a hair dryer’s suitability. Ceptics UP-100KU-WC specifications ↗

Check the AC socket’s permitted load at the voltage where you will use it against your exact dryer’s label and Dyson’s adapter requirement. A maximum watt rating stated at a higher voltage does not establish the same capacity at a lower voltage. If the instructions do not make the limit clear, ask the adapter manufacturer to confirm it before use.

A sufficient load rating also leaves plug fit, protective features and the dryer’s own voltage and frequency to check. A plug adapter does not convert voltage. We have not established compatibility between the Ceptics example and this dryer or any itinerary; it illustrates how to read separate ratings.

What to pack for Japan

No dryer in our current picks documents 100V. Plan on a suitable hotel dryer, or consider a 100-240V flat iron or curler for the styling jobs they can do.

THE PLUG CONNECTION

Plug adapter options for Japan

A plug adapter changes the plug shape, not the voltage. These destination options do not establish a match for your tool. Your tool must be rated for 100V. Check the actual outlet and the adapter's load rating. The Japan adapter is rated 10A, so at 100V its load ceiling is 1000W. Do not pair it with a higher-load dryer.

Confirm the label on the tool you receive.

Taking it to Europe or the UK instead?

The manufacturer-stated range includes 230V. Confirm the exact appliance label and use an adapter suited to the country and load.

If the answer remains unclear

Arrange a suitable local or hotel dryer rather than relying on an unresolved answer. This does not establish that every Supersonic Travel is incompatible with Japan. It also does not apply Travel specifications to other Supersonic versions.

Have a Supersonic Nural HD16 instead? See the limited voltage check for the reviewed US version ↗. Nural and Travel are different dryers; one model’s rating cannot answer for the other.

Document-based review: September 13, 2026. This model does not have a complete checker verdict. No hands-on testing claimed. Follow your exact model’s current label and manufacturer instructions.
