Japan Plugs, Sockets & Voltage: Do You Need an Adapter?
Official national electrical standards, wall socket pin configurations, standard voltage (100V), and appliance safety rules for visitors to Japan.
Quick Answer: What Plug Type Does Japan Use?
In Japan, power outlets strictly utilize Type A, Type B wall sockets operating at a standard domestic supply voltage of 100V and an alternating frequency of 50/60Hz. Visitors from foreign plug standards require a physical travel adapter, while dual-voltage appliances operate safely without voltage transformers.
