**Japan Ground Self-Defense Force Adopts MEDIROM MOTHER Labs'**

**REMONY for Advanced Health Monitoring and Heatstroke Safety**

**■Background of the Deployment**

In recent years, the importance of health management and heatstroke prevention for personnel operating under extreme conditions has grown significantly. Traditional wearable devices often face limitations in such environments—particularly in mountainous or remote areas where power supply is scarce—making it challenging to collect vital health data or detect anomalies in real-time continuously.

The *MOTHER Bracelet®* utilizes thermoelectric generation technology, enabling uninterrupted operation throughout training periods without concerns about battery depletion. This capability was a key factor in its adoption. By leveraging this technology, commanding officers and medical staff can remotely monitor the real-time health conditions of individual personnel during extended missions, allowing them to proactively identify risks such as heatstroke and take preventive measures before health-related issues escalate.
