A few decisions before departure can make your first day in Japan much easier. Check your travel documents, phone connection, ways to pay and route to your accommodation, then pack around the journey you have planned.
For travel from overseas, check Japan’s Ministry of Foreign Affairs and the Japanese embassy responsible for your place of residence. Requirements depend on your circumstances; the language you read this website in does not establish eligibility. Do this before non-refundable commitments, and keep travel documents and accommodation details accessible.
Compare an eSIM, physical SIM or portable Wi-Fi with your actual phone and group. Check device compatibility, activation timing, data allowance, hotspot use and collection or return arrangements. Download maps and essential confirmations for offline access. A shared router works only while the people using it stay within range.
Carry a usable payment card and access to some yen for places that need cash. Ask your bank about international use and fees. Save the hotel’s Japanese address and check-in details. Select the airport route to that exact address, with a backup if your flight arrives after the final connection.
Pack for the trip you booked
Prioritise comfortable walking shoes, layers for your destination and a bag you can manage on transfers. Check luggage limits with the airline and train service. Keep one outfit and daily essentials with you if forwarding a suitcase. Book only the activities that need fixed times and leave recovery time after long travel.
