About 終活アプリ SouSou - 想いを繋ぐエンディングサービス
----------
- Those leaving behind leave their wishes and messages after death.
- Those left behind share their memories of the deceased.
-----------
By consolidating previously scattered feelings in one place,
we have created a more convenient place to continue "connections" with more people after death.
■The Value of "Connections" I Felt at My Father's Funeral
The news of my father's death suddenly arrived, amidst a busy work life away from home.
I rushed home to attend the funeral, and many things came to mind,
but the best part was hearing from friends about my father's life and history, things I didn't know before.
Even after my father passed away, his history remains in the "connections" he made with others. These "connections" were extremely valuable not only to him, but also to me, his son.
I believe that using digital technology could make this experience more accessible and accessible to more people.
The "SouSou" end-of-life platform was born from this vision of our founder.
■Three Free Features
① Ending Note
A posthumous wishes notebook that can be completed simply by answering template questions.
・Family and friends can add original questions for you.
・You can set the visibility of each question category to only those you want to see it.
② Time Capsule Letter
A letter to a loved one that transcends time and can be delivered even after you've passed away.
・SouSou will deliver digital letters on your behalf after your death, celebrating future birthdays and important milestones.
・Photos can be attached.
・You can send letters by specifying dates such as birthdays or important events such as weddings.
③ Memorial Page
A digital memorial page that leaves a testament to your life and that of your loved ones.
・Even those who cannot attend the funeral or do not know the location of the grave can visit and collect farewell messages from various people online.
・Create an album of memorable photos.
・Create a timeline of the deceased based on memories of the deceased.
・You can even record your personal history while you're still alive.
■ Ensuring clear identity based on the My Number Card and implementing death determination
By utilizing the digital certificates of the "FPoS Library," issued by a certified certification authority under the Electronic Signature Act, identity verification is ensured and impersonation is impossible. This allows surviving family members and others to confirm the wishes of the deceased with peace of mind.
It also makes it possible to digitally determine death, reducing the burden on surviving family members by allowing them to receive various services without having to present a death certificate.
