Will my hair tools work in Japan at 100V?
Japan uses 100V. A 100–240V label includes that voltage; a range starting at 110V or 120V does not document 100V use. Frequency, plug fit, load and the exact model’s instructions still matter.
Japan has a nominal supply of 100V at 50/60Hz. The documented socket types are A, B.
The detail that matters
Japan’s 100V supply is lower than the starting voltage of some tools described as dual voltage. A 110-125V / 220-240V rating does not include 100V. Japan also has both 50Hz and 60Hz regions, so this comparison checks both frequencies.

Match the exact model before choosing
Compare the documented 100V styling options, then read the full StyleMax 77594 or Curl X 300299 record. Their voltage coverage is one part of the check; it does not approve every tool or outlet. A suitable local or hotel dryer is an option when your dryer’s 100V rating is unclear.

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.
