Inheritance Registration for a Naturalized Japanese Citizen of Southeast Asian Origin

Inheritance — reconstructing a naturalized citizen’s family history across two countries.

Background

The client was a Japanese individual whose late father was born in Southeast Asia and later acquired Japanese citizenship through naturalization. The father owned a condominium unit in Kanagawa Prefecture, and the client needed to complete the inheritance registration to transfer ownership.

Challenge

Because the deceased was a naturalized citizen, Japanese family registers alone could not establish his complete family history, and the records that could had to be assembled from more than one country, each with certified Japanese translations. In addition, the streamlined summary system commonly used for inheritance procedures is not available for cases of this type. Few offices are prepared to handle the combination of foreign public documents, immigration-related records, and Japanese real estate registration.

What We Did

We identified what was needed to prove the family relationships and reconstructed the deceased’s pre-naturalization family history from official records held in Japan and in the country of origin, coordinating retrieval through the client’s relatives. We prepared the estate division agreement, arranged certified translations, and explained to all heirs the inherent limits of the available records, obtaining their written acknowledgment. The registration was then filed online with the competent Legal Affairs Bureau.

Outcome

The application was accepted without any substantive correction, despite the unusual documentation involved. The client expressed appreciation for the clear explanations at each stage of a process that had initially seemed impossible to the family. Approximately three months from initial consultation to completion; ownership was successfully transferred.
