Planning a trip to Japan? Along with your passport and suitcase, one of the most important things you’ll need is the right gear to keep your electronics charged. Japan’s electrical system is unique: 100V power, A/B plug types, and even a split frequency (50 Hz in the east, 60 Hz in the west).
This doesn’t always match what you’re used to at home — and using the wrong plug or voltage can leave you with fried electronics or a dead phone a day into your trip.
This guide breaks it down by region and country, so you can scroll straight to your home area and know exactly what to pack.
🔌 Japan’s Electrical Basics
- Plug Types: A & B (two flat pins, sometimes with a ground pin)
- Voltage: 100V (lower than most of the world)
- Frequency:
- Eastern Japan (Tokyo, Sapporo, Yokohama): 50 Hz
- Western Japan (Osaka, Kyoto, Nagoya, Hiroshima): 60 Hz
✅ Dual-voltage devices (phones, laptops, cameras) → safe
🔥 High-heat appliances (hair dryers, curling irons, kettles, heating pads) → run weaker or may not work

✅ Quick Travel Electronics Essential Gear Checklist
These are always recommended to be packed regardless of where you are traveling:
🎒 Final Tips for Japan
- Always check your charger label: if it says 100–240V, you’re safe. In Japan since they have low voltage you’re safe from frying electronics without a converter, but they may be very weak or even unusable if you’re coming from a 200v+ home country.
- Hotels in Japan often have limited outlets → a small power strip can save the day.
- Japan is a very beautiful country, so bring a power bank to make sure your phone doesn’t run out of juice while you’re out and about taking photos.
- Skip packing high-heat appliances if at all possible (hair dryers, straighteners, heating pads) → use your hotel’s or buying one in Japan it likely your easiest option.
- A universal adapter is needed for a large part of the world visiting Japan, and is a good idea just in case when traveling internationally from any country.
