Japan Ground Self-Defense Force Adopts MEDIROM MOTHER Labs’ REMONY for Advanced Health Monitoring and Heatstroke Safety

TOKYO, Sept. 18, 2025 (GLOBE NEWSWIRE) — MEDIROM Healthcare Technologies Inc. (NASDAQ: MRM) (“MEDIROM”) today announced that its subsidiary, MEDIROM MOTHER Labs Inc. (“MOTHER Labs”), has begun providing its remote health monitoring system “REMONY,” powered by the recharge-free smart tracker MOTHER Bracelet^®, to the Japan Ground Self-Defense Force (JGSDF).

■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.

To address these challenges, there has been increasing demand in the field for devices that are lightweight, highly energy-efficient, and capable of long-term use without requiring recharging. In response, the Japan Ground Self-Defense Force 8th Division has adopted “REMONY,” a remote health monitoring system powered by the MOTHER Bracelet^®, a recharge-free smart tracker developed by MOTHER Labs.

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.
