Japan to Indonesia: Complete Plug & Adapter Guide (2026) Adapter Needed

Traveling from Japan to Indonesia means crossing into a different electrical system. Before you leave, take a moment to understand the plug types and voltage used in Indonesia so you can keep all your devices charged and ready.

There's no plug compatibility between Japan and Indonesia. Japan devices use Type A/B connectors, while Indonesia sockets are Type C/F. An adapter is a must-have for this destination.

Voltage is another key difference. Japan uses 100V while Indonesia uses 230V. If your device only supports one voltage, using it with the wrong supply could cause overheating or permanent damage. Look for "Input: 100-240V" on your charger. Most modern phone and laptop chargers support this range.

Rather than packing bulky converters, consider buying travel-sized dual-voltage versions of appliances you can't live without. For phones and laptops, all you'll need is the right plug adapter since their chargers almost always support worldwide voltage.
