No adaptor once you’ve landed? Airports and local shops are an option. But nothing beats the peace of mind of having your own ready to use.
Fukuoka is sometimes visited as part of a wider trip that includes South Korea and Taiwan. Worth checking plug details for those places — they don’t all use the same system.
Sockets in Fukuoka
In Fukuoka, you’ll find Type A and B plugs and sockets.
Type A

Type A sockets have two flat parallel pins and no grounding. Unlike Type G, they don’t include an earth pin, which makes them less secure.
Type B

Type B sockets have two flat parallel pins plus a round grounding pin. Unlike Type G, the pins are thinner and there’s no built-in fuse.
Do You Need a Voltage Converter?
Don’t assume your gadgets will work straight away in Fukuoka — the voltage isn’t the same as our 230 V, so a converter may be required.
Do check the voltage label on your kit before you travel. If it states ‘100–240 V, 50/60 Hz’, you’re safe to use it without a converter.
