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

Getting ready for your journey from Switzerland to Japan? 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 Switzerland plugs (Type C, J) won't fit Japan's outlets (Type A, B). You'll want to grab a universal travel adapter or one specifically designed for Japan before you depart.

Be aware that Switzerland runs on 230V at 50Hz, while Japan uses 100V at 50Hz/60Hz. 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.
