How to Charge Your Phone and Use Power Plugs in Japan: Complete Guide for Tourists

Japan is one of the most technologically advanced countries in the world, yet many visitors are surprised when their chargers don’t fit Japanese outlets. This guide explains Japan’s plug types, voltage, and adapter requirements so you can stay connected throughout your trip.

1. Japan’s Electrical Standards

• Voltage: 100 volts (V) — lower than most other countries. North America (110–120V) is compatible; Europe (220–240V) requires caution.
• Frequency: Eastern Japan (Tokyo): 50Hz / Western Japan (Osaka): 60Hz

Modern devices like iPhones, cameras, and laptops are dual voltage (100–240V), meaning you only need a plug adapter — no converter required.

2. Plug Types in Japan

Japan uses Type A plugs — two flat pins identical to North America. Some outlets also support Type B plugs (three pins), but not all.

3. Do You Need a Converter?

Check your device label — if it says Input: 100–240V, you’re safe with just an adapter. Devices like hair dryers or shavers from Europe (220–240V only) require a voltage converter to prevent damage.

Tip: Avoid cheap, unverified converters — overheating risk is high. Look for certified products with the PSE safety mark in Japan.

4. Where to Charge Your Phone in Japan

• FREE Cafés & Restaurants: Starbucks, Tully’s Coffee, and Doutor often have outlets or USB ports.
• FREE Train Stations: JR and Metro stations increasingly offer free or complimentary charging spots in waiting areas.
• FREE Airports: Haneda, Narita, and Kansai provide multiple free charging points airside and landside.
• FREE Convenience Stores: Many Lawson, FamilyMart, and 7-Eleven locations have USB power or seats with outlets.
• FREE Hotels: Front desks often lend adapters; some rooms have universal sockets.
