Family Registries

The Family Section

This is a sample layout which represents how a wife and children are noted within a koseki. These pages generally follow the koseki page in which the main family representative is noted (see either of the koseki sample pages appearing before this page).

While a koseki's format may vary depending the prefecture and year it was established, this example will hopefully provide a general overview of the layout. The kanji characters appearing in the title blocks on this form are read from right to left or from top to bottom.

Wife and children's koseki layout

A This section is the place where various dates and events are noted about the family. This section hosts two types of information, basically information about those coming into the family and information about those who leave the family. (If you have been denied access to your koseki touhon, it is possibly because of the names of various people noted in this section.) Appearing in this section are notes referred to as nyuuseki which state who was added to the koseki, when, and also for what reason. (For example births, marriages, adoptions.) Joseki notes are just the opposite of nyuuseki notes. They are notes which indicate who, when, and why someone was removed from the koseki. (For example deaths and divorce.)


B Chichi, the father of the individual whom the koseki is about (individual named in section E)

C Haha, the mother of the individual whom the koseki is about (individual named in section E)

D The birth order of the individual whom the koseki is about (individual named in section E) according to gender. The first born boy of a Japanese family is referred to as chounan. The second son born to the family is referred to as jinan. The third born son is referred to as sannan. The first daughter born to the family is referred to as choujo. The second daughter is referred to as jijo. The third daughter is referred to as sanjo. There are further birth order names according to gender (I'm told they're infinite), however there is a limit to the information we can offer on this page at this time. If you have a question about a birth order name according to gender, drop us a message and we'll try to field your question.

E Tsuma, wife. When children are noted in koseki, this character and the title bar are absent. In the case of either a wife or a child, their name is indicated here in the box below the title.

F Shussei, the individual's (individual named in section E) birth date. Years appearing in this section are based on the Japanese nengou or emperor year system.
