Connectivity
Choose eSIM, physical SIM, roaming, or rental Wi-Fi based on phone compatibility, group size, and whether you need a Japanese phone number. Do not discover a locked phone at the airport.

Decide, don’t just buy
Four decisions worth making early
Power
Japan commonly uses Type A plugs. Check the input range printed on each charger; a plug adapter changes the shape, not the voltage.
Money
Cards and contactless payments are common, but acceptance is not universal. Carry a backup card and some cash rather than relying on one wallet app.
Luggage
Large bags add stress in stations and on crowded trains. Compare delivery, lockers, hotel storage, and reserved luggage space before travel day.
