✅ 1. Final Travel Documents Check

These items should go in your carry-on, where they are easy to access:

  • ✔️ Passport (valid for at least 6 months)
  • ✔️ Boarding pass / flight confirmation (printed or digital)
  • ✔️ Accommodation details (hotel names and addresses in English & Japanese)
  • ✔️ Travel insurance info (policy number and contact)
  • ✔️ Visa, if required for your nationality
  • ✔️ Visit Japan Web customs QR code (printed or screenshotted)

💡 Tip: Keep them together in a slim travel wallet or document pouch.


📱 2. Digital Setup and Connectivity

These steps will ensure you’re connected and ready when you land:

  • 📲 Visit Japan Web registration completed and QR code saved
  • 📶 eSIM or SIM QR code downloaded / activation info printed
  • 📳 Roaming turned off (if not using international plan)
  • 🗺️ Google Maps, Google Translate downloaded for offline use
  • 🔋 Power bank fully charged (carry-on only – not allowed in checked bags)
  • 🔌 Japanese power adapter (Type A/B) packed

🧳 3. What to Pack: Carry-On vs. Checked Bag

Knowing what goes where makes airport security and arrivals much easier.

🧳 Carry-On Essentials (for the flight and emergencies):

  • 1–2 days’ worth of clothes (in case luggage is delayed)
  • Medications (with prescriptions if needed)
  • Noise-canceling headphones or earplugs
  • Eye mask, neck pillow, compression socks
  • Toothbrush, small toothpaste, hand sanitizer
  • Travel tissues, face masks
  • Charging cables
  • Reusable empty water bottle
  • Light snacks (granola bars, nuts, etc.)

🛑 No liquids over 3.4fl oz (100 ml) allowed in carry-on. Pack full-size toiletries in your checked bag.

🧳 Checked Luggage (for your stay in Japan):

  • Toiletries and liquids over 100 ml
  • Additional clothing, shoes, and jackets
  • Gifts or souvenirs
  • Umbrella (optional, but useful in Japan)
  • Items that are not allowed in the cabin (scissors, large batteries, aerosol cans)

💡 Tips: 1) Use a luggage tag to easily identify your bag and 2) get a TSA-approved lock to ensure your personal belongings stay safe


💸 4. Money and Payments

Japan still uses cash widely, especially at small restaurants and local shops.

  • 💵 Bring some Japanese yen if you exchanged in advance
  • 💳 Notify your bank about international travel
  • 🏧 Know your debit card PIN for ATM use (7-Eleven and Japan Post ATMs recommended)

Keep cash and cards in your carry-on or personal bag, never in checked luggage.


🚖 5. Ground Transportation After Arrival

You’ll thank yourself for preparing this ahead of time:

  • Airport transfer plans: train, airport limo bus, or hotel shuttle
  • JR Pass or IC card (Suica, Pasmo) ready or preordered
  • Hotel address printed and in Japanese (for taxi drivers)
  • Know how to find the train station from your terminal
  • Prepare small yen coins if you’re taking a local bus or paying cash

🍱 6. Food, Hydration & Comfort

Airplane food isn’t for everyone—and long-haul flights are tiring. Prepare:

  • Water bottle (fill it after security)
  • Light snacks that won’t spoil
  • Hydration tablets or electrolyte powder
  • Face wipes or moisturizer for dry cabin air

Pack all of these in your carry-on—they’re flight survival essentials.


😴 7. Sleep and Health the Night Before

  • Get to bed early, especially if you’re crossing many time zones
  • Avoid alcohol and heavy meals late at night
  • Set at least two alarms
  • Prepare comfortable clothes for the flight (layers recommended)
  • Check in online, if possible
  • Weigh your suitcase to avoid overweight fees

✈️ Final Tips

  • Arrive at the airport at least 3 hours before departure
  • Screenshot everything: QR codes, directions, reservation numbers
  • Keep a small folder or clear pouch for printed items
  • Bring a pen for forms
  • Make sure your phone is fully charged before leaving home
