🔍 Why This Route Matters
The journey from Japan to United States of America isn't just about flights and hotels; it's about making sure your devices actually work when you arrive. You'll catch a break with plugs: Type A/B works in both Japan and United States of America. The 20 volt difference between Japan (100V) and United States of America (120V) is minor. Most electronics auto-adjust. Uses 12H time format (e.g., 11:00 PM). A little preparation goes a long way on this route.

Airport & Arrival Tip
JFK handles millions of travelers annually, and power access has improved significantly. Most airport lounges have ample outlets and USB ports. Worth the day pass if you have a long layover. Many ride-share drivers have USB chargers available. Don't hesitate to ask. Check into your hotel/Airbnb first before exploring. Test your adapters and charge devices fully.
Packing Advice
Lucky you. Identical electrical systems mean no adapters or converters needed. Power banks must go in carry-on luggage (not checked bags). TSA and international rules are strict about this. Pack extra charging cables. They're easy to lose and expensive to replace abroad. Take a photo of your adapter setup before you leave. It'll help you remember what goes where.
Seasonal Considerations
Time of year matters for power planning in United States of America, especially if you're visiting during temperature extremes. **Summer travel:** Summer heat means aggressive air conditioning. Battery life suffers in cold indoor environments. **Winter travel:** Cold weather kills battery life quickly. Keep devices close to your body to maintain charge. **Holiday season:** Year-end travel often means budget hotels with fewer outlets. Plan device priorities. Whatever the season, arrive with everything fully charged. You can't predict your first day's access to power.
