Lost Your Smartphone in Japan? Here’s What to Do Right Away

Losing your phone while traveling can feel like a nightmare — it’s not just about the device, but your photos, messages, and personal data.
Take a deep breath.
Japan has one of the highest recovery rates for lost phones in the world — 83% are returned to their owners.
Follow these simple steps to protect your data and maximize your chances of getting your phone back safely — even if you’ve already left Japan.

Step 1: Locate and Lock Your Phone Remotely


Your first priority is protecting your data.
Use your phone’s tracking feature to locate and lock it.

Tips
  • You can lock your phone even without a passcode
  • Apple automatically disables Apple Pay
  • You can display a custom message or contact info on the lock screen

Step 2: If You See the Location — Contact or Visit the Place


If tracking shows the phone’s location, act immediately.
LocationWhat to Do
HotelCall the front desk
Restaurant / CaféContact them during business hours
Train or StationCall the Lost & Found counter
TaxiContact the taxi company or dispatch center
If someone has already turned it in — great news!
Confirm ownership and retrieve it as soon as possible.

Step 3: If No Location Appears — Retrace Your Steps


If the map doesn’t show a signal, don’t give up yet.
Think back through your recent stops — restaurants, train rides, shops — and contact each place.
The earlier you reach out, the higher your recovery chances.

Step 4: File a Lost Property Report with the Police


Filing a Lost Property Report (Ishitsubutsu Todoke) ensures you’ll be contacted if your phone is found later.

Why it matters:

  • 🧾 You’ll receive a report number needed for insurance or replacement claims
  • 🔍 If someone turns it in, police will match it to your report
  • 📱 Bring your IMEI number (found on the phone box or contract) to make identification easier

Step 5: Take Additional Security Precautions


Even after reporting the loss, protect your accounts and personal data.
  • 🔐 Change passwords for Google, Apple, social media, and email
  • 💳 Suspend linked cards (Apple Pay, Google Pay, banking apps)
  • 📶 Suspend your SIM card with your carrier
  • ☁️ Check your cloud backup (iCloud, Google Drive, or Photos)
  • 🚫 Log out of all devices remotely if possible
