(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 DeploymentIn 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.■About the Japan Ground Self-Defense Force 8th DivisionThe Japan Ground Self-Defense Force 8th Division is responsible for the defense of southern Kyushu and disaster relief operations in the region. The division conducts a wide range of training and missions to ensure the safety and security of local communities.HP: <a href="https://www.mod.go.jp/gsdf/wae/8d">https://www.mod.go.jp/gsdf/wae/8d</a>■About the MOTHER Bracelet, Recharge-Free Smart Tracker<figure><img src="https://images.microcms-assets.io/assets/9edf8dbea622483096fe2cacad989656/558ef391dcc94961b2a4f358f63ae5fe/MOTHER_%E3%83%AA%E3%83%AA%E3%83%BC%E3%82%B9%E7%B4%A0%E6%9D%90.jpg?w=750&amp;h=421" alt="" width="750" height="421"></figure>MOTHER Bracelet is the world&apos;s first* 24/7 recharge-free smart tracker.

(NASDAQ: MRM) (“MEDIROM”, “we” or “us”) announces that its “REMONY for Driver” remote health management system, developed by its subsidiary MEDIROM MOTHER Labs Inc. (“MOTHER Labs”), has been selected by Japan’s Ministry of Land, Infrastructure, Transport and Tourism (“MLIT”) under its Accident Prevention Support and Promotion Program as a certified device for preventing fatigue-related driving.■ About REMONY for Driver“REMONY for Driver” is a remote health management system that leverages the MOTHER Bracelet, which can be worn 24/7, 365 days a year, to centrally manage drivers’ health conditions and alertness. In particular, the system features a proprietary sleep assessment function developed under medical supervision, enabling both the streamlining of safety check-in roll-call operations and the strengthening of safety management. Because the device requires no charging, the operational burden at worksites is kept to a minimum.In addition, the accumulation of daily health data allows for trend analysis of drivers’ rest conditions, which we believe will contribute to the prevention of health-related accidents before they occur.Example Use Cases: - Conducting safety check-in roll-call operations based on objective health data - Enhancing safe-driving education through sleep assessment - Supporting driver health and improving workplace environments■ Overview of the Subsidy Program“REMONY for Driver” has been certified by the MLIT under its Accident Prevention Support and Promotion Program as a device contributing to the prevention of fatigue-related driving, and is therefore eligible for the following subsidy:● Subsidy rate: 50% of the equipment acquisition costIn this program, MLIT allocated approximately 1.3 billion yen in subsidies during the previous fiscal year, and we believe a similar budget is expected for the current fiscal year. The subsidies are subject to certain caps, including a general cap of 800,000 yen per business operator for fatigue prevention devices.By utilizing this subsidy program, companies can significantly reduce initial introduction costs and accelerate the implementation of safety measures in the field.■ Future OutlookBuilding on the certification of “REMONY for Driver” as an eligible subsidy device, MOTHER Labs intends to further promote safe driving practices and strengthen measures to prevent fatigue-related driving in the transportation industry. Moving forward, we aim to enhance system functionality and ensure comprehensive health management for drivers, thereby raising industry-wide safety standards and working toward the goal of zero accidents. Our company remains fully committed to supporting transportation operators in creating an environment where they can operate with confidence and peace of mind.■ About the MOTHER Bracelet, Recharge-Free Smart Tracker<figure><img src="https://images.microcms-assets.io/assets/9edf8dbea622483096fe2cacad989656/558ef391dcc94961b2a4f358f63ae5fe/MOTHER_%E3%83%AA%E3%83%AA%E3%83%BC%E3%82%B9%E7%B4%A0%E6%9D%90.jpg?w=400&amp;h=225" alt="" width="400" height="225"></figure>MOTHER Bracelet is the world&apos;s first 24/7 recharge-free smart tracker.

(Headquarters: Minato- ku, Tokyo; CEO: Kouji Eguchi; NASDAQ: MRM) (the “Company”, “we” or “us”), which operates a diversified healthcare business, announced its participation in “World,” a “proof of human” protocol co- founded by Sam Altman and Alex Blania. The purpose of this project is to build a new digital infrastructure that will enable &quot;proof of humanness&quot; in the age of AI. As part of this project, we intend to install the World ID authentication device, the &quot;Orb&quot;, in approximately 100 of our Re.Ra.Ku, relaxation salons. Our goal is to provide access to a verified World ID to a network of up to 500,000 individuals.In addition, those who verify their World ID can choose to claim the equivalent of approximately 8,000 Japanese yen in Worldcoin tokens (“WLD”) (based on current WLD prices). Soon, customers will be able to use WLD to purchase gift certificates (&quot;Re.Ra.Ku Tickets&quot;) that can be redeemed at Re.Ra.Ku relaxation salons.Once this program has launched, when customers purchase Re.Ra.Ku Tickets, the Company plans to acquire WLD. However, while considering the liquidity and balance sheet risks that the Company can tolerate on a case-by-case basis, the Company plans to exchange up to 50% of the acquired WLD for the cryptocurrency Ethereum (ETH) and hold it, while analyzing and managing the trends in the cryptocurrency market. Our goal is for these assets to enhance our future financial strategy and drive business expansion.Our Company aims to create new value and achieve sustainable growth by going beyond the scope of the healthcare business and integrating with next-generation digital infrastructure.

The Ministry of Health, Labor and Welfare implemented the Specific Health Guidance Program for medical insurance subscribers aged 40-74, primarily to prevent lifestyle-related diseases. Specific health checkups (specific health examinations) by public health nurses and registered dietitians provide support and guidance for improving diet and exercise habits to those who are determined to be at risk of metabolic syndrome. Depending on the checkup results, the health guidance offered is classified as &quot;motivational support&quot; or &quot;active support&quot; and aims to establish healthy behaviors through continuous follow-up. It is an essential initiative to extend healthy life expectancy and reduce medical expenses.■Features of Specific Health Guidance Using the &quot;Lav&quot; Healthcare App: This is a healthcare app that allows users to understand and manage their health status while recording activity levels such as weight, steps, sleep, and daily meals. Within the app, users can receive advice tailored to their individual goals through chat with professional coaches, making health promotion more accessible and easier to continue. In addition to specific health guidance services, we offer a variety of programs that can be used by those with a high interest in health, such as fasting and diet programs. The style of working closely with a dedicated personal coach makes it easy to ask questions and consult, and the app is designed to be user-friendly even for beginners. By recording daily lifestyle habits, we provide ongoing support to raise awareness of one&apos;s health naturally.<figure><img src="https://images.microcms-assets.io/assets/9edf8dbea622483096fe2cacad989656/8f3fb1cac6474cc59f2c56b34a02a509/lav%20(1).jpg" alt="" width="4756" height="3200"></figure>▼Lav App iOS (AppStore) <a href="https://apps.apple.com/jp/app/lav/id1460111723">https://apps.apple.com/jp/app/lav/id1460111723</a>▼Lav App Android (GooglePlay) <a href="https://play.google.com/store/apps/details?id=jp.co.medirom.lav.client.android&amp;hl=ja&amp;gl=US">https://play.google.com/store/apps/details?id=jp.co.medirom.lav.client.android&amp;hl=ja&amp;gl=US</a>▼Inquiry Form/Detailed Information <a href="https://medirom.co.jp/contact/tokuho">https://medirom.co.jp/contact/tokuho</a>Market and Industry Data This press release contains references to market and industry data, which have been obtained or derived from publicly available information, market research reports, and/or industry publications and surveys.
