The blank space of the passport photo information page is damaged, but the information is complete, the photo is fine, and the barcode is also there. Can it be used in Japan?

You are emphasizing that the damage to your passport is minor, but this does not mean that you are 100% sure to be able to enter Japan. It can only mean that the problem is not serious. If you apply for expedited application for a blank passport, two It's better to go with this passport. Came down within a week.

If you really don’t have time, you can only try your luck...
