On September 14, 2026, Family Storage was fully renewed and officially launched. The Family Map, family records, anniversary reminders and the AI Storyteller are all free to use.
Head of household, household succession, retirement, extinct household — old family registers are full of words no longer in use. We explain them one by one with their readings, noting “which era of register you will meet them in.”
Templates are convenient, but they can cause trouble later. We cover the differences between the three formats, what to look for when choosing, and where people tend to get stuck.
Each family register costs ¥450 or ¥750. So how much does it come to in total? We explain typical costs when you do it yourself and how to read the prices of a service.
The pricing unit, how far back they trace, what you receive, how long it takes, and how your information is handled. We have narrowed down the things worth checking before you entrust the work to five.
Including everyone is not automatically the right answer. We explain how degrees of kinship are counted, how to decide based on your purpose, and what paper size to expect.
Gathering family registers is the most time-consuming part of making a family tree. We cover the differences between the three types of register, who can request them, and when to use mail requests versus nationwide issuance.
Easy-to-read family trees share a common shape: who to place at the center, how to connect the lines, and how much to include. We also cover the differences between drawing by hand and making one on screen.
You can now use the new Family Storage ahead of its official opening. All the records you have registered so far have been carried over just as they are.
We have rebuilt everything — the family tree, personal records, anniversaries and even the AI Storyteller. You can now create your family tree with just your fingertip, even on a smartphone.
The “standard household” of a married couple and their children is no longer the majority. As family forms become more single-person and more diverse, we think again about the value of keeping records.
As Japan enters a “society of many deaths,” inheritance procedures and disputes are on the rise. We look at why it matters to sort out your family line and relationships early.
