Do US electronics work in Japan?

Yes, mostly. Japan uses the same plug types (A and B) as the US, but lower voltage (100V vs 110V). Modern devices handle this automatically, but check older electronics. The bigger issue is having enough charging ports.

Should I buy a JR Pass app or keep paper?

Keep both. Download the JR East app for schedules and platform info, but physical JR Passes are still required for most tourists. The app helps with navigation but doesn't replace the actual pass.

How much data will I use in Japan?

Heavy usage families use 3-5GB per week with constant map checking, translation apps, and photo uploads. Unlimited pocket WiFi (around 5,000 yen/week) often costs less than international data overages.

Can I use my camera everywhere in Japan?

Most places yes, but many temples, museums, and some restaurants prohibit photography. Look for camera prohibition symbols. Street photography is generally fine but avoid photographing people without permission.

How to pack tech gear for a family trip to Japan

Pack universal power adapters with USB ports, portable chargers for all devices, and download offline maps and translation apps before you go. Japan uses Type A and B outlets (same as US), but bring adapters anyway for international devices and extra charging capacity.

Check your devices work with Japanese power. Japan uses 100V electricity with Type A and B outlets (same plugs as US). Most modern devices handle 100-240V automatically, but check older items. Bring a universal adapter with multiple USB ports - you'll need more charging spots than wall outlets provide.
Download essential apps before departure. Get Google Translate with camera function, Google Maps offline for Tokyo/Kyoto areas, Hyperdia for train schedules, and IC Card Reader if using Suica cards. Download these on WiFi at home - international data is expensive and WiFi isn't everywhere.
Pack portable chargers for everyone. Bring one 10,000+ mAh power bank per family member. Walking days in Japan drain phone batteries fast with constant map checking, photo taking, and translation app use. Anker and RAVPower work well and are available in Japan if you forget.
Organize charging cables and adapters. Pack all charging cables in one packing cube or tech pouch. Bring extras - Japanese electronics stores carry international cables but they're pricier than home. Include car chargers if renting a vehicle.
Consider a portable WiFi router. Rent a pocket WiFi device at the airport (3,000-5,000 yen for a week) or buy a Japan SIM card. Hotel WiFi works but isn't available while out exploring. Pocket WiFi supports multiple devices and costs less than international roaming for families.
