Can I buy adapters in Tokyo instead?

Yes, but they're expensive and time-consuming to find. Electronics stores like Bic Camera have them, but you'll pay 2-3x what you'd pay at home and waste vacation time shopping.

Do I need a voltage converter for my hair dryer?

Most likely yes. Japan's 100V will make most hair dryers run slower and potentially damage them. Check your device's voltage range or plan to buy one in Tokyo.

How much data will I need for a week in Tokyo?

Plan for 1-2GB per day per person for navigation, translation, and communication. A family of four should get at least 30GB for a week-long trip.

Can I charge my phone on Japanese trains?

Some Shinkansen and newer train cars have outlets, but most local trains don't. Don't count on train charging — bring fully charged devices and portable batteries.

How to Pack Electronics for a Family Trip to Tokyo

Pack your electronics with Japanese plug adapters (Type A and B), portable chargers rated for 100V, and download offline maps before you go. Bring power strips for hotel rooms and keep backup chargers in carry-on luggage.

Get the right power adapters. Japan uses Type A and B plugs at 100V. Buy adapters before you travel — they're expensive in Tokyo. Get at least 2 adapters per family member, plus one spare.
Check your device voltage compatibility. Most modern electronics work with 100-240V, but check labels. Hair dryers, curling irons, and some gaming devices might not work or could be damaged by Japan's lower voltage.
Pack a portable power strip. Tokyo hotel rooms often have limited outlets. Bring a compact power strip with surge protection to charge multiple devices from one outlet.
Download essential apps offline. Download Google Maps offline for Tokyo, Google Translate with Japanese language pack, and Hyperdia for train schedules. Test everything before you leave.
Organize charging cables by person. Pack each family member's cables in separate pouches. Include USB-C, Lightning, and micro-USB as needed. Bring backup cables for phones and tablets.
Pack portable battery banks. Tokyo requires lots of walking and phone use for navigation. Pack 10,000mAh+ battery banks — one per teenager/adult. Keep these in carry-on bags only.
Prepare devices for international use. Enable international data plans, download currency converters, and save important phone numbers offline. Take photos of important documents and store them locally on devices.
