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.

Here’s a quick breakdown:

Use a Japan Plug Adapter if:

• Your device says “Input: 100-240V”

• 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
