SouSou Co., Ltd. (Headquarters: Kawaguchi City, Saitama Prefecture; Representative Director: Kazusa Kusaka), which operates the end-of-life platform "SouSou," commenced a new service on May 12, 2026, to print and deliver bound copies of ending notes to users' homes, following its PDF output function launched in December 2025.
With this service, ending notes created on the app are output and bound into a physical booklet, complete with electronic signature information. By making information stored on smartphones accessible in a tangible form, families can easily find necessary information without confusion during critical moments.
Furthermore, this service has also established a payment environment by leveraging Welnet Co., Ltd.'s (TSE Standard/Sapporo Stock Exchange Main Market, Stock Code: 2428; Headquarters: Sapporo City, Hokkaido; President: Kazuhiro Miyazawa; hereinafter "Welnet") "Multi-Payment Service."
Purpose of This Function:
- To allow users to keep a paper copy of their ending note at hand.
- To make it easier to share with those unfamiliar with smartphones or apps.
- To transform digitally recorded information into a more easily stored and handled format.
Background:
In recent years, the movement to organize and manage information using smartphones and apps has been spreading in end-of-life planning. "SouSou" also provides an environment where information can be securely managed on the app.
However, there remains a strong demand for keeping important information in paper form, storing it as a booklet, and making it easier to share with those unfamiliar with smartphones or apps.
Therefore, "SouSou" developed this service, believing it is crucial to achieve a state where, in addition to digital convenience, information can be handled more easily and utilized according to its purpose by being preserved as a paper booklet.
Service Overview:
1. A Booklet for Quick Access to Necessary Information:
Carefully printed and bound based on the content created in the app. The cover includes the name and creation date, allowing for immediate identification of the individual's information.
2. Designed for Easy Reading by Anyone:
The font size and layout adopt a design that is easy to read for all generations. The structure ensures that families can confirm information without confusion.
3. QR Code Linked with Electronic Signature:
By scanning the QR code on the back cover, users can check the electronic signature verification results and the signature date and time. This allows for later confirmation of "when the individual's wishes were made."
4. Easy Ordering via SouSou App, Delivered to Your Home:
Bookbinding can be easily ordered through the app. The completed booklet will be shipped within 10 business days. It can be used for home storage or sharing with family.
5. Payment Supported by Multi-Payment Service:
Welnet's "Multi-Payment Service" is adopted for payment for this service. It supports various payment methods, aiming to improve user convenience.
Important Notes:
This ending note is intended for recording one's wishes and thoughts and is not a legally binding will.
Future Outlook:
"SouSou" will continue to prioritize both digital convenience and ease of use in practice, advancing the creation of mechanisms to reduce the burden of "searching" and "getting lost" in end-of-life planning.
It's not just about recording; it's about ensuring that necessary information reaches those who need it, when they need it, reliably. We will continue to expand our services to achieve this.
What is the End-of-Life Platform "SouSou"?
"SouSou" is a new digital end-of-life planning service utilizing My Number Card. It offers various necessary functions for end-of-life planning, such as ending notes, completely free of charge and as a one-stop service. It also has three unique features not found in conventional services: 1. Assurance of identity/authenticity, 2. Digitization of death verification, and 3. Linkage with external services (data). Moving forward, we aim to automate and simplify various procedures after death through collaboration with various partner companies.
