Do I need a voltage converter for Japan?

Usually no. Japan uses 100V, and most modern electronics (phones, laptops, cameras) are rated for 110-240V. Check your device labels—if it says 110-240V, you only need a plug adapter, not a voltage converter.

Can I buy electronics in Japan if I forget something?

Yes, but it's expensive. Phone chargers at convenience stores cost $20-30. Electronics stores like Yodobashi Camera have everything but at full retail price. Better to pack spares.

Will my phone work in Japan?

Modern unlocked phones work fine on Japanese networks. However, data roaming is expensive ($10+ per day). Rent pocket WiFi or buy a prepaid SIM at the airport for much cheaper internet access.

Should I bring a power strip?

Yes, especially for hotels. Many Japanese hotel rooms have only 1-2 outlets, and they're often inconveniently located. A small 3-outlet power strip solves charging problems for the whole family.

How to Pack Electronics for a Family Trip to Japan

Bring a universal adapter with Type A and Type B plugs, pack portable chargers for long days out, and consider renting a pocket WiFi device. Japan uses 100V electricity, which works fine with most modern electronics, but check your devices before traveling.

Check your device voltage compatibility. Look at your chargers and electronics for voltage ratings. Japan uses 100V/50-60Hz. Most modern phones, laptops, and tablets (110-240V rated) work fine, but some hair dryers, curling irons, and older devices may not.
Pack the right adapters. Bring a universal adapter with Type A (two flat prongs) and Type B (two flat prongs plus ground) plugs. Skip expensive Japan-specific adapters—a basic universal one costs $10-15 and works everywhere.
Bring multiple portable chargers. Pack one 10,000mAh power bank per person. Days in Japan involve lots of walking, train transfers, and photo-taking. Your phones will drain faster than usual, especially with GPS and translation apps running.
Download essential apps before departure. Install Google Translate (with offline Japanese), Hyperdia or Google Maps for trains, and IC Card apps if staying longer than a week. Download these on home WiFi to save data.
Plan your internet access. Either rent a pocket WiFi device ($6-8 per day) or buy a prepaid SIM card at the airport. Pocket WiFi works for the whole family and is often cheaper than international roaming for multiple devices.
Pack charging cables strategically. Bring one extra charging cable per device type. Japanese convenience stores sell cables, but they're marked up. Pack cables in your carry-on in case checked bags are delayed.
