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.
