Record the loss and contact the right issuer

Osaka’s guide explains that a lost-passport case involves the police and the embassy or consulate of the passport holder’s country. Record when you last had the passport, when you noticed it missing and the likely location. Contact a transport operator or facility’s lost-property service when relevant, while also checking the official replacement process.

Follow police instructions for reporting the loss and retain the report details or receipt number. Ask your embassy or consulate what replacement or emergency travel document it can issue and which supporting evidence is required. National procedures differ, so do not assume that another traveller’s document list applies to you.

Coordinate travel and residence records

Keep a secure copy of the old passport if you have one, but understand that a copy is not itself a travel document. Tell your diplomatic mission about any urgent travel and discuss the available official options. Verify airline and destination requirements separately before buying a replacement itinerary.

After a new document is issued, ask Japanese immigration whether any record, endorsement or other procedure is needed in your circumstances. The city guide points to immigration for this follow-up, but the correct action should be confirmed case by case. Keep a single timeline of police contact, replacement and planned travel. Do not publish passport numbers or identity photographs while asking for help online. If other cards were also lost, contact each issuer separately; replacing a passport does not suspend a bank card or replace a residence card.
