Exhibit 99.1

MEDIROM Mother Labs Partners with TD SYNNEX to Accelerate
National Adoption of “MOTHER Bracelet” and “REMONY”

(“MOTHER Labs”), which develops health-tech solutions, has entered into a distributor agreement (the “Agreement”) with TD SYNNEX K.K. (“TD SYNNEX”).

Through the execution of the Agreement, MOTHER Labs will collaborate with TD SYNNEX to leverage its nationwide sales network and extensive expertise in IT product distribution, with the aim of accelerating the nationwide expansion of the recharge-free smart tracker “MOTHER Bracelet®” and the remote health monitoring system “REMONY®,” both developed by MOTHER Labs.

◼︎ 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.

◼︎ REMONY®︎, Remote Health Monitoring System

‘REMONY’, a remote health monitoring system, developed by MOTHER Labs, combines the wrist-worn recharge-free smart tracker MOTHER Bracelet with a dedicated gateway. The system enables automatic data synchronization and centralized real-time management.

However, MOTHER Bracelet measures user vital data in real-time 24/7 without needing removal for recharging. As a result, it allows for prompt and early detection of health emergencies and accident prevention with high accuracy. The system is customizable for use in various industries, including elder care, health monitoring for night shift workers, etc.

Features:
