Traveler checking for lost phone in Tokyo station

Losing your phone in Japan doesn't have to ruin your trip — follow these simple steps to get it back fast.

📱 Step-by-Step: What to Do If You Lost Your Phone in Japan

1️⃣ Stay Calm and Act Quickly

Japan's lost and found system is extremely organized, but time matters.
As soon as you realize your phone is missing, note where you last had it — train, taxi, restaurant, or street.

2️⃣ Call or Visit the Right Place

Depending on where you lost it, the responsible authority differs:

Train: JR East, Tokyo Metro, or private line's Lost & Found center
Taxi: Contact the taxi company (receipt number helps!)
Street / Restaurant: Go to the nearest koban (police box)

💡 Tip: Many train companies transfer found items to police after 2–3 days.

3️⃣ Prepare This Information Before You Call

When contacting Lost & Found (or using LostCall AI), you'll need:

Phone model and color (e.g., iPhone 14 Black)
Brand and case color
Date and approximate time lost
Location (station name, shop, or taxi route)
Contact email

If possible, have your IMEI number ready (you can find it in your device box or carrier app).

4️⃣ Use "Find My iPhone" or "Find My Device"

Apple: iCloud.com/find
Android: Find My Device

Even if the phone is offline, you can lock or erase it remotely.

5️⃣ Report to the Police (交番)

In Japan, every found phone must legally be handed to the police if not returned to a company.
Go to the nearest koban and file a report — they'll give you a certificate ("遺失届出書") that you can show to your embassy or carrier.

6️⃣ Solve the Language Barrier — Let AI Call for You

AI making calls to Japanese lost and found centers

Most staff at Lost & Found centers speak little or no English, which can be stressful.
