Ending App 'SouSou' Launches Pre-Contract Notification Service for Memorial Diamond Maker Algordanza Japan

On June 10, 2026, So-So Inc. (Headquarters: Kawaguchi, Saitama Prefecture; Representative: Kazusa Kusaka), operator of the ending platform 'SouSou', announced a partnership with Algordanza Japan (Headquarters: Shizuoka City, Shizuoka Prefecture; Representative: Masaki Hozuki), the Japanese subsidiary of a Swiss firm that creates diamonds from cremated remains, to launch a 'Pre-Contract Notification Service.'

Through this collaboration, Algordanza Japan's memorial diamond services will be introduced within the 'SouSou' app, and pre-contract details will be synced to the platform. In the event of a client's passing, Algordanza Japan will be able to provide the bereaved family with essential contract details and necessary procedures on behalf of the deceased.

Background of the Partnership
In recent years, values regarding funeral and end-of-life services in Japan have diversified. Beyond traditional graves, new options such as scattering remains, tree burials, and keeping remains at home are gaining popularity. Memorial diamonds, gaining attention since the 2000s, are part of this trend. However, end-of-life services often involve a long gap between 'contracting' and 'execution.'

While formalizing a contract might seem complete, So-So Inc. believes a service is only truly fulfilled when the client's wishes are honored at the necessary time. Given the highly ethical nature of 'executing the wishes of the deceased,' society demands structural solutions to address issues such as: missing information sharing with families, information failing to reach families in time, or family circumstances overriding the deceased's intent. This partnership aligns Algordanza Japan's commitment to 'supporting clients until the end' with 'SouSou's' information coordination infrastructure.

How 'SouSou' Works
'SouSou' connects the needs of users who want their wishes fulfilled and service providers who want to ensure contract execution. Users verify their identity using a My Number card and register their pre-contracts. Upon death, proprietary 'Digital Death Detection' technology is used to notify families and partners, guiding them through necessary procedures.

Partnership Details
1. Service Introduction: Promoting Algordanza Japan's memorial diamond services within 'SouSou'.
2. Contract Syncing: Integrating pre-contract data into the platform.
3. Notification to Families: Automatically sharing death notifications to ensure survivors receive information, coupled with 'SouSou's' ending-note function to prevent information gaps.

Future Outlook
'SouSou' intends to expand partnerships with providers in funerals, inheritance, and insurance to continue building a reliable information infrastructure that connects the deceased's wishes with families and businesses.
