MENTAGRAPH Inc. is a wellness-tech company born from D-LAB, the corporate R&D organization of JT (Japan Tobacco Inc.).
We analyze emotional fluctuations based on biometric data and design experiences that transform those insights into awareness and everyday actions.
Through devices such as smart rings, mobile apps, and eye-mask devices that combine sound and warmth, we create opportunities for people to reconnect with their authentic selves.
What matters is not reacting to numerical data when emotions shift, but staying honest with how you feel.
Through technology and design, MENTAGRAPH fosters a culture of awareness and offers services that support the well-being of every individual.
Until now, we have recorded and managed physical health through tools such as body composition scales and blood pressure monitors. Yet what shapes our focus, motivation, relationships at work, and sense of happiness is something far less visible: our state of mind.
We believe that in the near future, people will naturally keep an emotional rhythm log—understanding their emotional condition just as they do their physical condition—and build better days through small, informed choices.
MENTAGRAPH aims to become the infrastructure that supports this future.
By visualizing emotional fluctuations, we enable people to choose lifestyles, ways of working, and relationships that truly suit them. Over time, these choices accumulate into personal well-being and collective strength.
Our vision is a society where everyone can understand their own mind and design their own actions.
MENTAGRAPH is committed to making this a shared norm, establishing emotional richness as a foundation for the next era.
