Since 2015 · Trusted
Eleven years of proven experience working with family histories.
Now we bring that expertise to a new "platform for stories."
The records you gather about your family reveal all kinds of things. Special days appear automatically, and memories come alive as stories.
The more people you register, the clearer the picture of your family becomes. No complicated steps are needed. Just keep records, and everything is organized automatically.
Birthdays, death anniversaries and wedding anniversaries are shown automatically from your family's information. There is no need to register them one by one.
You can show your family's special days in Google Calendar or your iPhone calendar. They are added as yearly recurring events, so you only need to set it up once.
Based on the records you have gathered, the AI answers like a storyteller. You can confirm in words how each person is connected.
Just turn it on in My Page settings. Your family's anniversaries and events will automatically appear in your Google Calendar.
Save "Use calendar sync" in My Page settings, and your own personal subscription URL will be shown.
Just paste it into "From URL" in Google Calendar. No complicated settings needed.
Yearly anniversaries and advance reminders alike are updated automatically every few hours.
* No extra app to install. Check everything in your usual calendar, on a smartphone or a computer.
Family Storage is not just a place to keep records.
It quietly stays by your side in your days with your family.
We automatically find important days in the family records you have registered and let you know. There is no need to enter the dates again yourself.

Both features are available just by signing up (free).
16px body text with 1.8 line spacing. Readers of every generation can read it without zooming in.

No need to scroll tables sideways on your smartphone. Each item is turned into its own card.
Upcoming events are shown large at the top. You can also add them to the calendar you use every day.
From the records you have written down, AI turns your family's story into text. You can also listen to it as audio.

◍ Hover your mouse over a number (or tap it on a smartphone) to see a detailed explanation of that step below.
The most difficult partFamily registers cannot be requested without authorization from the person themselves or a relative. For this reason, this one procedure requires paper and a seal. We automatically create the letters of authorization from the details you entered and show you with diagrams where to put your seal and where to send them, so you are less likely to get stuck along the way.
Production assistance for "Family History." We have created a great many family trees.
Family Storage is run by Tradition Blue Co., Ltd., a company experienced in family tree research.
We share service updates and important announcements.
The press release we issued for the full renewal and official launch on September 14, 2026, was published on @Press, NEWSCAST and Zero Press. Here are the links.
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.
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.
It is a service for reliably preserving and sharing your family's records (family tree, photos, memories and special days). From “Family Research,” which traces the family register (koseki), to creating a family tree, AI storytelling, and managing photos and special days, you can gather your family's story in one place.
Yes. Sign-up is free. Basic use, such as creating a family tree and saving records, is free of charge. Only some services, such as Family Research (family register research), are paid.
No. There are no difficult operations. Simply follow the screens and enter names and records.
Yes. You can use it on a smartphone, tablet or computer. You can also add it to your home screen and use it like an app (PWA). It launches quickly, and you can also receive notices (push notifications).
Your family tree takes shape simply by adding family members, starting from yourself. Additions are always registered as “relationships as seen from you,” and you can zoom and move around with your fingertip. You can share your completed family tree with your family by printing it or saving it as a PDF.
Yes. When you register birthdays, death anniversaries, other anniversaries and so on, we will notify you automatically as the day approaches (in-app notices, push notifications and email). You can also sync with Google Calendar and check them in your usual calendar.
It is a feature in which AI talks about a person based on the family records you have registered. If you ask, “What kind of person was my grandfather?”, it answers within what is in the records. It is designed to be modest: it does not make up things that are not recorded, and instead tells you “That is not in the records.” It can also read aloud, and you can choose a calm voice (Japanese, Korean and English).
Yes. From each card in the family tree, you can open a photo gallery just for that person. With a share link, you can also show photos only to your family and relatives (people who don't know the link cannot browse the list).
Yes. The records and photos you register are your own. Please use the service with peace of mind.
The fees for family register (koseki) documents are as follows, per copy (as of September 2026; the amounts are the same in almost all municipalities).
If you request them by mail, the issuing fee for fixed-amount postal money orders (¥200 each) and postage both ways are added. The number of documents ranges from a dozen or so to more than thirty depending on the family, and the total generally comes to around ¥10,000 to ¥20,000-something per lineage.
For details, please see The Cost of Making a Family Tree, and for the request procedure, How to Request Family Registers. If you would like us to do it for you, the fees are listed under How much does it cost?
