Tokyo, Japan – June 25, 2026 – MEDIROM MOTHER Labs Inc. (Headquarters: Minato-ku,
Tokyo; President: Yoshio Uekusa), a subsidiary of MEDIROM Healthcare Technologies
Inc. (Headquarters: Minato-ku, Tokyo; CEO: Kouji Eguchi; NASDAQ: MRM), hereby
announces that it has received an additional order from the 8th Division of the
Japan Ground Self-Defense Force (JGSDF) for its remote health monitoring system,
"REMONY®", which utilizes the charge-free smart tracker, "MOTHER Bracelet®."

Against the backdrop of a growing need for heatstroke prevention and health
monitoring during prolonged training, the JGSDF highly evaluated the system for its
ability to operate continuously without charging, even under harsh training
environments. As a result, the scale of deployment has expanded to approximately
three times that of the initial implementation.

MOTHER Bracelet
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.
