Tokyo, Japan – July 31, 2025 – MEDIROM Healthcare Technologies Inc. (Headquarters: Minato-ku, Tokyo; CEO: Kouji Eguchi; NASDAQ: MRM; hereinafter referred to as “MEDIROM”) has collaborated with Hakuhodo Inc. to participate in “World,” a “proof of human” protocol built for the AI era, co- founded and chaired by Sam Altman (founder of OpenAI).

Through this collaboration, Tools for Humanity (Headquarters: San Francisco, USA; Co-founder and CEO: Alex Blania; Co-founder and Chairman: Sam Altman; hereinafter referred to as “TFH”) aims to accelerate the adoption of “World ID,” a system that verifies an individual’s authenticity as a “real human being,” within the “World” protocol it is promoting.

Going forward, MEDIROM will progressively install the “Orb” World ID authentication device in approximately 100 of its “Re.Ra.Ku” relaxation salons, aiming to achieve cumulative deployment in over 100 stores by the end of December 2025 and issue 500,000 new World IDs annually.

■ About World

World is a proof of human protocol built for the AI era. It enables individuals to verify their humanness online—without compromising privacy. The project was co-founded by Sam Altman, Alex Blania, and Max Novendstern. World is a global initiative to build tools that help humanity prepare for the age of AI. Co-invented by Sam Altman, Alex Blania, and Max Novendstern, World aims to increase trust online by using World ID to distinguish between humans and AI. Its mission is to build a new global economic system where only real humans can access currency and services. Tools for Humanity, co-founded by Altman and Blania, leads the implementation and global deployment of this project.

■ About World ID

World ID is a global personal authentication technology that proves “humanness.”
In recent years, with the rapid evolution of generative AI, we are entering a society where it is difficult to distinguish between humans and AI. Against this backdrop, World ID aims to provide “digital proof of human”.

The “Orb,” an advanced camera, is used to verify humanness of individuals without identifying them.
Once verification is complete, a verified World ID is issued and stored in “World App,” enabling its use across various compatible services.
