A safety management solution leveraging the world’s first* battery-free smart tracker,
accelerating deployment through a low-initial-cost package

April 16, 2026, Tokyo, Japan – MEDIROM Healthcare Technologies Inc. (NASDAQ: MRM) (“MEDIROM”) today announced that its subsidiary, MEDIROM MOTHER Labs Inc. (“MOTHER Labs”), under a distributor agreement with TD SYNNEX Corporation (Headquarters: Tokyo, Japan President: Shigetaka Kunimochi), will begin nationwide offering of a rental plan for heatstroke prevention for its remote health monitoring system “REMONY®︎,” which utilizes the battery-free smart tracker “MOTHER Bracelet®︎.”

Background: Mandatory Heatstroke Prevention Measures and On-Site Challenges

In recent years, record-breaking summer heat has made heatstroke prevention in the workplace an urgent issue. In particular, following the revision of the Climate Change Adaptation Act on June 1 last year, companies are now required to implement more advanced safety management and operational systems for on-site workers.

However, the introduction of devices to monitor workers’ vital signs in real time has posed significant challenges. High upfront capital investment costs, along with the operational burden of managing such systems after implementation, have made it difficult for companies to proactively adopt these solutions.

Key Features of the “REMONY” Heatstroke Prevention Rental Plan

This plan is a comprehensive package that visualizes workers’ vital data in real time and helps prevent heatstroke risks before they occur.

1. Low Initial Investment Package

Adopts a rental model with no need to purchase devices. Enables flexible operation tailored to corporate budgets, such as usage only during necessary periods.

2. Zero Charging, 24/7 Operation

Utilizes proprietary technology based on the Seebeck effect, which generates power from the temperature difference between the body and the surrounding air. This eliminates data loss due to missed charging and reduces operational burden.

3. Alert Notification Function

Automatically notifies administrators immediately upon detecting abnormalities, enabling centralized management of safety across multiple sites.

Value Delivered Through Partnership with TD SYNNEX

Through TD SYNNEX’s nationwide sales network, this solution can be rapidly delivered to regional manufacturing and construction sites that face challenges related to IT literacy and implementation costs. By leveraging TD SYNNEX’s expertise in IT distribution as the primary point of contact, we will continue to enhance our services to support the health and safety of workers.

■MOTHER Bracelet®︎, Recharge-Free Smart Tracker

MOTHER Bracelet®︎ is the world's first* 24/7 recharge-free smart tracker, powered by advanced technology from a Silicon Valley-based tech business that generates electricity from the temperature difference between the body and the surrounding air. As it doesn't require recharging, it eliminates the data loss that can occur when a device is taken off for charging. This single device can record five fundamental health metrics: heart rate, calories burned, body surface temperature, step count, and sleep.
