Germany → Japan

No. Your Type C and Type F plugs from Germany will not fit Japan's sockets. You'll need a travel adapter.

The voltage in Japan is 100V. This is lower than Germany's 230V. Your devices may work at reduced power.

No, you don't need a voltage converter. The voltage difference (230V to 100V) is safe for most modern devices, especially laptops, phones, and chargers which typically support 100-240V dual voltage.

Japan uses Type A, B sockets. You will see these socket types in hotels, airports, and public places throughout the country.

Yes, most modern electronics (iPhones, laptops, tablets, cameras) are dual-voltage (110V-240V), so they will work in Japan. Since Japan uses 100V (within the 100-240V range), your device will work fine. You'll need a plug adapter to fit the wall socket.

You can buy a Type A travel adapter online (Amazon, eBay) or at the airport. Look for adapters specifically designed for Japan or universal adapters that include Type A. Check our Amazon link above for the best options.

If you don't use an adapter, your plug physically won't fit into Japan's sockets. Additionally, if the voltage is different (230V vs 100V) and your device isn't dual-voltage, you could permanently damage your device or cause a fire hazard. Always use the appropriate adapter and check voltage compatibility.
