Can I Use My Android Phone Charger in Japan?

Your Android phone charger can work in Japan if its actual input rating, frequency and plug match the local supply.

Conditional compatibility

Use directly only if your actual input rating covers the local voltage and frequency and your plug fits with any required grounding. A typical category profile does not confirm your own unit.

Why

Use directly only if your actual input rating covers the local voltage and frequency and your plug fits with any required grounding. A typical category profile does not confirm your own unit. Android and USB-C fast chargers are dual-voltage (100–240V). They work worldwide with just a plug adapter — no converter needed.

Japan runs 100⁠V / 50/60⁠Hz. Japan uses 100V — the lowest standard mains voltage of any developed country. Plugs look identical to US Type A/B, but the lower voltage means even a US 120V device runs slightly weaker. The frequency is split: 50Hz in the east (Tokyo), 60Hz in the west (Osaka). This matters only for motor- and clock-based devices, not for 50/60Hz-labeled chargers.

How different input labels change this answer

Calculated examples for reading labels, not a test of your unit. Compare your actual label before using an example result.

Japan: 100⁠V · 50/60⁠Hz

  • Input: 100–240V~ 50/60Hz → Conditional compatibility
  • 100-240V 0.5A → Conditional compatibility
Final check: look for "INPUT 100-240V" or a matching local voltage on the label before you plug in.
