Tokyo, Japan – October 9, 2025: MEDIROM MOTHER Labs Inc. (Headquarters: Minato-ku, Tokyo; President and CEO: Yoshio Uekusa; hereinafter “MOTHER Labs”), a subsidiary of MEDIROM Healthcare Technologies Inc. (NASDAQ: MRM), today announced that it has approved a private placement of new shares to two officers, Yoshio Uekusa, President and CEO, and Ryo Saito, Director, as part of its Series A financing round, at a valuation of JPY9 billion. Funding is scheduled to occur by the end of October.

◼︎Background for Implementation

MOTHER Labs serves as the health tech division within the Medilom Group, having previously implemented specific health guidance programs using the healthcare app “Lav” and promoted the development and sales of wearable devices. To accelerate further business expansion, we determined that strengthening rapid decision-making and a management structure rooted in the field is essential. Therefore, it was decided to conduct this capital increase with the management team itself becoming investors, aiming to further heighten business responsibility and growth motivation.

◼︎Future Outlook

Through this capital increase, MOTHER Labs will strengthen its capital base while advancing the development of an upgraded version of its wearable device, the MOTHER Bracelet, and establishing systems for bringing products to market.

As the Medilom Group, we will realize new value creation in the healthcare and wellness field and further drive business growth both domestically and internationally.
