| Item | Do You Need It? |
|---|---|
| Japan Plug Adapter (Type A/B) | ✅ Yes – must-have for Singapore plugs |

What Type of Power Plug & Plug Socket Does Japan Use?

Japan uses Type A and Type B power plugs:
- Type A: Two flat parallel pins (most common)
- Type B: Two flat pins + one round grounding pin (less common, but still found in some places)
🧠 Note: Japan’s Type A sockets are non-polarised, meaning both prongs are the same size. If you’re using a U.S. or Singapore plug with one wider prong, it might not fit older Japanese outlets!

Is Japan’s Power Plug the Same as Singapore’s?
Nope. Singapore uses Type G (three rectangular pins), while Japan plug sockets use flat-pin Type A/B.
That means:
- ✅ You will need a Japan plug adapter
- ⚠️ You might need a voltage converter for single-voltage appliances

Japan Voltage vs Singapore Voltage
- Japan: 100V (split by region)
- 50Hz in Eastern Japan (Tokyo/Hokkaido)
- 60Hz in Western Japan (Osaka/Kyoto)
- Singapore: 230–240V at 50Hz
Many modern devices (phones, tablets, laptops) are dual-voltage (100V–240V), so they only need a plug adapter, not a converter.
⚠️ Single-voltage devices (e.g., hair dryers) can be damaged by Japan’s lower voltage. Always check your device label before packing!

Do You Need a Japan Power Plug Adapter or a Voltage Converter?
Here’s a quick breakdown:
✅ Use a Japan Plug Adapter if:
- Your device says “Input: 100-240V”
- You’re charging phones, tablets, laptops, or cameras
- You only need to physically fit the Japan plug socket
⚠️ Use a Voltage Converter if:
- Your device says “Input: 220-240V only”
- You’re bringing high-powered appliances like hair dryers, straighteners, or kettles
- You want to avoid frying your gear
✍️ Tip: Check the label on your charger or power brick before you pack.
