“Do I need a power adapter for Japan? Will my devices work?”

Maybe! It depends on where you’re from and what devices you have.

Japan’s Plugs

“What type of plug does Japan use?”

Type A plugs:

• Two flat prongs
• Same as USA, Canada, Mexico
• No ground prong (third pin)

If you’re from USA/Canada:

• Your plugs will work!
• No adapter needed for most devices

If you’re from Europe/UK/Australia:

• You need an adapter
• Easy to find and cheap

Voltage

“What about voltage?”

Japan uses 100V

• USA/Canada: 120V (close enough)
• Europe: 220-240V (different!)

Check your devices:

• Look for “INPUT: 100-240V” on chargers
• Most phone/laptop chargers work worldwide
• Hair dryers and straighteners often don’t!

What Works Without Adapter

“What devices are usually OK?”

Usually fine (check label):

• Phone chargers
• Laptop chargers
• Camera chargers
• USB devices
• Tablets

May have issues:

• Hair dryers
• Hair straighteners/curlers
• Electric shavers (some)
• High-wattage devices

What to Do

“Should I buy an adapter?”

My advice:

• Check your device labels first
• Buy a universal adapter before traveling
• Hotels sometimes lend adapters
• Don’t bring high-wattage items

What Japanese People Actually Do

Most locals:

• Use 100V devices designed for Japan
• Don’t think about voltage issues
• Know visitors need adapters sometimes
