Carry on only Japan packing essentials and Backpacker Japan packing list lightweight gear

• Favorite snacks or small toys for trains and flights
• A lightweight stroller or a baby carrier

Japan adapter charger pack and voltage basics

Japan adapter charger pack and voltage basics are often overlooked, but they really matter. Japan uses 100V power and Type A plugs (two flat pins). Here’s what that means for you:

• North American two-pin plugs usually work without an adapter
• European or three-pin plugs require an adapter
• High-watt devices (hair dryers, straighteners) must be dual-voltage to avoid damage

Pocket WiFi vs SIM Japan: how to choose

Choosing between Pocket WiFi vs SIM Japan depends on your travel group size, data usage, and how light you want to travel. A quick guide:

• Groups & families: Pocket WiFi shared by multiple devices is cost-efficient
• Solo travelers or short stays: eSIM or physical SIM keeps you lightweight
• Remote work or heavy streaming: choose a high-data or unlimited plan

Even if you plan to rely on hotel WiFi, it’s common to run into situations where you need maps or translation outdoors. If safety or privacy matters to you, my guide on Hotel WiFi safety in Japan may help you choose the right connection method.
