✓ A physical adapter may be required
✓ Your device's printed voltage rating covers this destination's 100V supply; verify wattage and connector separately
✓ Japan uses both 50Hz and 60Hz regions; verify frequency-sensitive equipment.

Six separate compatibility questions
Voltage
Electrical potential; incompatible single-voltage devices may be damaged.
Frequency
50Hz or 60Hz can affect motors, clocks and some appliances.
Transformer / converter
Changes voltage for a suitable load; it is not the same as an adapter.
Universal supply
An input label such as 100–240V, 50/60Hz usually supports both systems within its rating.
USB-C Power Delivery
The charger, cable and device must negotiate a supported voltage/current profile.
PLUG ADAPTER QUESTIONS
Frequently asked questions
No. A plug adapter only changes the physical pin shape to fit a different socket. If your device is not rated for the destination's voltage, you need an actual voltage converter, which is a separate product.
