A Message from Daisuke Mori

Thank you for visiting Apostille Japan. I am Daisuke Mori, Apostille & Certified Translation Specialist and registered Gyoseishoshi (Japanese Administrative Scrivener).

Apostille Japan handles MOFA apostille procedures and Certified Translation for Japanese documents submitted to the United States, the United Kingdom, Singapore, New Zealand, and the Philippines.

The required process may differ even for the same type of Japanese document depending on the receiving authority, purpose of submission, issuing authority, and instructions provided for the specific procedure. We therefore confirm these points before determining the Japan-side authentication and translation steps.

Our current destination scope is limited to five countries so that each matter can be reviewed against the document and receiving-authority requirements within our service scope. For an initial inquiry, please provide the destination country, receiving authority, document name, desired deadline, and whether the document has already been issued.

Why Is the Current Service Scope Limited to Five Destinations?

Current Destination Scope

Apostille Japan currently handles Japanese documents intended for the United States, the United Kingdom, Singapore, New Zealand, and the Philippines. Authentication and translation requirements may differ not only by destination country but also by receiving authority, document type, issuing authority, and purpose of submission.

For that reason, we limit the current destination scope and confirm the required Japan-side steps for each matter rather than treating one country as having one fixed authentication route.

Current Scope Five Destinations Currently Served

Japanese documents intended for receiving authorities in the United States, the United Kingdom, Singapore, New Zealand, and the Philippines are within our current destination scope.

Destinations
  • United States
  • United Kingdom
  • Singapore
  • New Zealand
  • Philippines
Outside Current Scope Other Destination Countries

Other destination countries are generally outside our current service scope. Requirements may involve local translator qualifications, embassy or consular procedures, or other country-specific systems. Please confirm the applicable requirements with the receiving authority or an appropriate professional in the relevant jurisdiction.
