**MEDIROM Partners with World on Technology Envisioned <br>by Sam Altman and Alex Blania: Deploying "Proof of Human"** 

**Infrastructure throughout Japan**

![Graphic](mrm-20251229xex99d1002.jpg)

**■ Background and Purpose of the Collaboration**

In recent years, advances in generative AI have made it extremely difficult to distinguish between "humans" and "AI" online, creating a global challenge to establish trust online. To address this challenge, Sam Altman and Alex Blania co-created World. World aims to provide a mechanism, utilizing blockchain technology, that allows anyone worldwide to safely and fairly prove they are human ("Proof of Human") without revealing their identity.

MEDIROM shares this vision and established a special task force, the "MEDIROM World Proof of Human Task Force."

------

![Graphic](mrm-20251229xex99d1003.jpg)

The Company will begin full-scale collaboration in Japan with TFH and WF to bring the World Proof of Human verification technology to people throughout Japan. MEDIROM will drive access across diverse fields beyond its existing footprint of relaxation and wellness retail locations. The Company expects such expansion to contribute to a future where everyone can participate in the digital society with confidence through the social implementation of "Proof of Human."

**■ Key Initiatives**

● Availability of Orbs, an advanced camera deploying privacy-preserving technologies to verify humanness, in approximately 300 Re.Ra.Ku Group locations

● Establishment and operation of flagship locations offering Proof of Human verification services

● Deployment of Proof of Human verification pop-up stores in commercial facilities and public spaces

**■ Comment from Koji Eguchi, President and CEO of MEDIROM**

We are excited to launch this collaboration in Japan with Tools for Humanity and World Foundation. As generative AI rapidly permeates society, we firmly believe that this new social infrastructure for "proving one's humanness" will become an indispensable foundation for the future digital society.

Through this collaboration, we seek to broaden our reach with new approaches, such as establishing flagship locations and pop-up stores, to build an authentication environment that more people can use with confidence. We intend not only to grow this initiative into a new revenue model but also to contribute to building trust within Japan's digital society, further accelerating our evolution as a health tech company.
