Tsunamamo product offering
Product offeringCore offering
Tsunamamo develops and distributes GOOSE (グース), a free smartphone application for end-of-life planning and elderly care monitoring. The app combines a life log notebook for recording medical history, insurance details, contacts, property, and pet care instructions with a patent-protected anomaly detection feature that sends alerts when smartphone usage indicates a potential emergency. Information can be shared continuously with family or conditionally disclosed only during emergencies, with all data stored on high-specification cloud servers with advanced encryption.
Product overview
GOOSE is a single unified smartphone application for life logging and end-of-life planning. The app combines three core functional modules: (1) Anomaly Detection for passive elderly monitoring via smartphone usage patterns, (2) Constant Information Sharing for ongoing sharing of medical, insurance, and contact information, and (3) Emergency Disclosure for privacy-protected delivery of critical information during emergencies. The app is free to download on iOS and Android, with partner registration enabling 2+ person sharing networks.

Tsunamamo competitors and assessment
Company assessmentDirect peers
- 絆-kizuna- (Anshin Lab): A Japanese end-of-life preparation and digital legacy service offering similar life-log and post-mortem information management features. Directly comparable to GOOSE because it competes in the same niche of digital end-of-life notes and family information sharing for Japanese consumers.
- みまもりほっとライン: A Japanese elderly monitoring service for families and municipalities, providing phone-call based check-ins and emergency escalation. Comparable to GOOSE because it addresses the same 'remote monitoring of elderly loved ones' use case, though it uses voice calls rather than smartphone usage patterns as the monitoring signal.
Broad incumbents
- FamilySearch (by Ancestry): A global family-tree and digital legacy platform that allows users to preserve family information, stories, and records. Comparable to GOOSE because it addresses the same 'preserving family information for future generations' value proposition, though with a genealogical rather than end-of-life planning focus.
- Secom (セコム): Japan's largest security services company, offering elderly monitoring services including 'Secom Home Security' and 'My Doctor' emergency call services. Secom is a broad incumbent in the elderly care and monitoring space with established B2C distribution and an existing customer base, addressing overlapping needs (peace of mind, emergency response) as GOOSE.
- いい相続 (ii Souzoku): A Japanese platform that connects consumers with inheritance, end-of-life planning, and wills professionals. Comparable to GOOSE because it addresses the same life-planning and end-of-life information organization needs, though it does so through a marketplace B2B2C model rather than a direct consumer app.
- ALSOK (綜合警備保障): Major Japanese security company providing elderly monitoring services including 'HOME ALSOK Home Security' and 'Anshin Support' packages. Comparable to GOOSE because it offers emergency notification and family peace-of-mind services for elderly households, though distributed through a manned security infrastructure rather than a software-only model.
- Google Inactive Account Manager: Google's built-in feature for managing digital legacy and triggering information sharing when an account goes inactive. Comparable to GOOSE because it provides a free, large-scale alternative for some of the same digital legacy and emergency disclosure functions, and could erode GOOSE's market if it expands its features.
- Apple Digital Legacy (Apple ID Legacy Contact): Apple's built-in feature allowing users to designate legacy contacts who can access their iCloud data after death. Comparable to GOOSE because it provides a platform-native version of the emergency disclosure feature, and represents a real threat as a free, pre-installed alternative.
Others
- Home Net Corporation (ホームネット株式会社): The parent/operating entity of the GOOSE app itself. Listed as the legal entity behind Tsunamamo and the GOOSE product in the Japanese corporate registry. Relevant to flag because GOOSE's strategic direction is governed by this entity's broader portfolio decisions.
Emerging players
- まごチャンネル (Mago Channel): A Japanese family communication service that delivers photos and voice messages from grandchildren to elderly relatives via a dedicated device. Comparable to GOOSE because it targets the same demographic of adult children caring for distant elderly parents, with a focus on non-intrusive connection and emotional wellbeing.
