Japan to Guinea-Bissau: Complete Plug & Adapter Guide (2026) Adapter Needed

Getting ready for your journey from Japan to Guinea-Bissau? Electrical compatibility is easy to overlook, but bringing the wrong plug or forgetting an adapter can leave you scrambling at your hotel. Here's what you need to know.

Your Japan plugs (Type A, B) won't fit Guinea-Bissau's outlets (Type C). You'll want to grab a universal travel adapter or one specifically designed for Guinea-Bissau before you depart.

Be aware that Japan runs on 100V at 50Hz/60Hz, while Guinea-Bissau uses 220V 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.

A universal travel adapter with multiple plug configurations is a smart investment if you travel frequently. For Guinea-Bissau specifically, look for one that supports Type C outlets. USB charging ports built into the adapter are a nice bonus.
