Tokyo, Japan – September 25, 2025 – MEDIROM Healthcare Technologies Inc. (Headquarters: Minato-ku, Tokyo; CEO: Kouji Eguchi; NASDAQ: MRM), a diversified healthcare company, has joined “World,” a “proof of human” protocol co-founded by Sam Altman and Tools for Humanity’s CEO, Alex Blania. MEDIROM plans to complete the deployment of the World ID proof of human authentication device Orb across 100 of its Re.Ra.Ku relaxation studios in Japan within this month, and to expand the deployment to 200 locations nationwide further. This expansion marks the largest installation of Orbs in Japan to date, providing greater access to this new social infrastructure that enables individuals to prove their unique humanness.

Through the integration of healthcare and technology, MEDIROM is committed to driving the adoption of World ID in Japan.

■About World ID

World ID is a global 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.
