TRIAS Launches 'Cocowa'

In a bid to provide安心 to families living apart, TRIAS Corporation, based in Minato, Tokyo, has officially unveiled its innovative monitoring service 'Cocowa' which will be available across Japan starting December 16, 2025. This service leverages cutting-edge Internet of Things (IoT) technology to allow families to check in on their loved ones remotely using a human-sensing sensor linked exclusively through LINE, a popular messaging app in Japan.

'Cocowa' Overview

The core concept behind 'Cocowa' is simple: monitor family members who live separately while respecting their privacy. Utilizing human-sensing sensors, any unusual inactivity can trigger notifications sent via LINE. This system does away with traditional surveillance techniques as it doesn't rely on cameras, reducing both the psychological burden on users and the privacy concerns of family members.

Currently, 'Cocowa' is being piloted in select areas across five municipalities: Nerima and Tachikawa in Tokyo, Tagajo in Miyagi Prefecture, Moriguchi in Osaka Prefecture, and Ichinomiya in Aichi Prefecture. Starting April 2026, the service will extend to Yokohama City in Kanagawa Prefecture as well.

Key Features of 'Cocowa'

• - Seamless Integration with LINE: The entire process from registration to receiving daily notifications is conducted through LINE, requiring no additional app installations. Users get daily activity reports and alerts if inactivity exceeds a certain threshold.
• - No Installation Visits Required: The device setup is incredibly straightforward – the monitored family member simply plugs it into a power outlet. Hence, there are no complicated installation processes or necessary visits from technicians.
• - No Internet Connection Needed: Designed to work without an internet connection, Cocowa includes built-in communication functions that eliminate the need for wiring or installations.
• - Family Accessibility: Notifications can be shared with up to three family members per contract, ensuring that relatives can stay informed.
• - Privacy Protecting Technology: The absence of cameras ensures that personal privacy is respected, with the sensor only tracking movement within the home.
• - Flexible Contract Terms: Users can freely opt-out on a month-by-month basis, providing flexibility as lifestyles and circumstances change.
• - Pricing Structure: Initial costs are set at ¥19,800 (including tax, with free shipping), and the monthly service fee is ¥3,300. In celebration of the launch, the first month of service is being offered for free.

Addressing the Need

TRIAS Corporation was established in May 2025 with a mission to harness technology's advantages for everyone. Recognizing the rising challenges among families, especially regarding privacy and access to technology, the need for a simple and non-invasive monitoring solution has become paramount. In Japan, the aging population is projected to grow significantly, with solitary households among those aged 65 and above rising from approximately 6.17 million in 2020 to over 10.83 million by 2050. This demographic shift amplifies the urgency behind reliable and respectful monitoring systems like 'Cocowa'.

TRIAS aims to bridge the gap, allowing families to remain connected while ensuring the privacy of their loved ones is safeguarded. As societal needs continue to evolve, services like Cocowa are positioned to play a crucial role in supporting family relationships across distances.

Collaboration with Local Governments

Various partnerships with local governments are integral to the spread of 'Cocowa'. As of December 2025, arrangements have been made with the following municipalities to include Cocowa in their senior monitoring support initiatives:

• - Nerima, Tokyo: Subsidies for ICT device installation costs.
• - Tachikawa, Tokyo: Senior Safety Monitoring Support Project.
• - Tagajo, Miyagi: Assistance provide for seniors monitoring services.
• - Moriguchi, Osaka: Graceful senior monitoring support plan.
• - Ichinomiya, Aichi: ICT-assisted monitoring service grants for single-living seniors.

Moreover, Yokohama City is set to include Cocowa in its offerings beginning April 2026, with further details to follow.

Future Developments

The commitment to enhancing the Cocowa experience will persist as TRIAS seeks to refine the service and develop functionalities that further meet customer needs. By fostering partnerships with local enterprises and municipalities, TRIAS continues to contribute to creating an environment where families live together, even when physically apart.
