When planning your Japan travel, don’t overlook one key detail: how to keep your phone and camera charged.
It’s common for travelers to get stuck in hotels or cafés with issues like “no outlets available” or “the plug doesn’t fit.”
This guide covers everything you need to know about Japan’s power outlets, how to choose the right travel adapter, using mobile batteries, and taking advantage of nationwide rental services like ChargeSPOT—so you can explore Japan without running out of power.
1. Power Outlets in Japan: Basics You Should Know (Plug Type, Voltage, Frequency)
Japan’s electrical outlets have some unique features compared to other countries. Knowing the basics will help you enjoy a stress-free stay.
◯ Plug Type: Type A (two flat pins)
- Japan uses Type A outlets, the same as in the U.S. and Canada.
- Travelers from those countries can usually plug in directly.
- Visitors from Europe or parts of Asia, where different plug shapes are common, will need a plug adapter.
◯ Voltage: 100V
Japan runs on 100V, which is lower than most regions worldwide.
- U.S.: 120V
- Europe: 220–240V
- Southeast Asia: 110–240V
If your device doesn’t support 100V, plugging it in could cause damage or even fire hazards.
◯ Frequency: 50Hz (East Japan) / 60Hz (West Japan)
- Eastern Japan (Tokyo, Sapporo, etc.): 50Hz
- Western Japan (Osaka, Fukuoka, etc.): 60Hz
Most phone and laptop chargers are dual-frequency (50/60Hz), but some appliances like hair dryers and shavers may not work properly.
◯ Key Takeaways
- Always bring a plug adapter (essential for European/Asian travelers).
- Some devices may require a voltage converter.
- Outlets in hotels are sufficient, but in cafés and public spaces, free power outlets are limited—a mobile battery is highly recommended.
2. Choosing the Right Plug Adapter for Japan Travel
For Japan travel, a Type A adapter is a must-have.
Many modern adapters also include extra features that make charging easier:
- Basic Type A adapter for Japan
- AC + USB port combo adapters (charge multiple devices at once)
- Models with USB-A and USB-C support (ideal for modern phones and laptops)
Pro tip: Choose an adapter with USB ports to avoid charging troubles in hotels or airports.
3. Mobile Batteries and Rental Services for Japan Travel
During sightseeing, apps like maps, transit guides, and translators can quickly drain your phone battery.
That’s when a mobile battery (power bank) becomes a lifesaver.
⚠️ Important: Mobile batteries must go in carry-on luggage
- Airlines do not allow power banks in checked luggage.
- Always carry them in your hand luggage.
- Check airline restrictions in advance, as larger-capacity batteries may have limits.
Even if you don’t bring your own, Japan has widespread mobile battery rental services, including:
- ChargeSPOT
- PowerNow
- MT Charge
Among these, ChargeSPOT is the most convenient, with over 54,800 rental stations (as of June 2025) nationwide.
