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

Planning a trip from Japan to Brunei? One of the first things to sort out before you travel is whether your electronics will work at your destination. Power outlets, plug shapes, and voltage standards vary around the world, and Brunei is no exception.

The plug types are different between these two countries. In Japan, outlets accept Type A/B, but in Brunei you'll find Type G sockets. A travel plug adapter is essential for this trip.

Be aware that Japan runs on 100V at 50Hz/60Hz, while Brunei uses 230V at 50Hz. This voltage difference matters for appliances like hair dryers, curling irons, and electric shavers that aren't dual-voltage. Check the label on your devices. If it says "100-240V," you're fine. Otherwise, you'll need a voltage converter.

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.
