Lost Something on a Train or Shinkansen in Japan? Do These 3 Things Before Giving Up

You left your bag on the seat… or forgot something on the overhead shelf of a Shinkansen. By the time you realized, the train was already gone. Losing an item while traveling in an unfamiliar place can be incredibly stressful.
But don’t worry—Japan has one of the highest return rates for lost items in public transit. In this guide, we’ll walk you through the first steps you should take, and how to increase your chances of getting your lost item back quickly and smoothly.

Step 1: Stay calm and talk to the nearest station staff


If you’ve just gotten off the train, the fastest way to act is to speak directly to the station staff at the ticket gate or information window.
They can
✅ Check if the item has already been turned in
✅ Contact the next station or the final stop to check for you

Step 2: Identify the train company and contact them


If you’ve already left the station or didn’t realize the item was lost right away, you’ll need to contact the train company that operates the line you were on.

Helpful details to provide

✅ Approximate time and station where you boarded/disembarked
✅ Where you were sitting (even general info like “near the front of the train” helps)
✅ A detailed description of the item (color, size, brand, contents)

Not sure which train company you used?

  • 🪪 If you used an IC card (Suica, PASMO, etc.), check your ride history via the app or at a ticket machine
  • 📱 Use Google Maps or a transit app to review your route and identify the operator
Some major stations like Shibuya or Shinjuku are served by multiple operators (JR, private rail, subways), so be specific.

Step 3: Submit a Lost Property Report to the Police


If contacting the train company doesn’t help—or you’re unsure where you lost the item—you can file a Lost Property Report with the local police.

Why it's worth doing

  • If someone turns in your item to a police station, they can match it with your report
  • It creates an official record of your claim

What happens to lost items

  1. Found: Someone (a passenger or staff) finds your item.
  1. Temporarily stored: It’s kept at the station office.
  1. Moved to the company’s central lost and found center (after 1–2 days)
  1. Transferred to the police: If unclaimed, it’s handed over in 3–7 days

How to submit a report

  • Visit the nearest police station or koban (police box)
  • In some prefectures, you can submit the report online.

Final Tip: Time Is of the Essence


Lost items in Japan often make their way through multiple locations: from the train to the station office, then to the train company center, and finally to the police.
The longer it takes, the harder it gets to trace your item. That’s why taking quick action is critical.
