Family Register/ Koseki Tohon Translation

Updated: Apr 2, 2019

First, the golden rule of Family Register/ Koseki Tohon translation:

To be accepted, the certified translation your Family Register/ Koseki Tohon translation needs to be faithful to the original, not only in the words translated, but also in the formatting. Translations which differ visually from the formatting style of the original document make it more difficult for the official reviewing the document to accept it. This increases the risk of your translation being rejected.

Types of Koseki Tohon:

As there are many types of Koseki available, perhaps you are not certain about exactly which type of you have? Here is an explanation of the various types available:

There are two main types of Koseki, the Koseki Tohon ( 戸籍謄本 ) and the Koseki Shohon

(戸籍抄本). The Koseki Tohon is a complete Koseki of all members of a family, showing details of their birth, death and marriage. The Koseki Shohon is different; it contains a similar record- but for one individual member of the family only.

"...your Family Register/ Koseki Tohon translation needs to be faithful to the original, not only in the words translated, but also in the formatting".

A third type of Koseki also exists, a Koseki Joseki Tohon (戸籍除籍謄本). These Koseki contain details which have been removed from the Koseki mentioned above as a result of a death or divorce in the family.

An older style of Koseki, known as a Kosei-Gen-Toseki-Tohon (改製原戸籍謄本) also exists. These can come in two formats (the Showa-era format and the Heisei-era format), and are usually available upon request from the archive section of your local government office.
