MENTAGRAPH Inc. (Head office: Chuo-ku, Tokyo; a wholly owned consolidated subsidiary of JT) will be exhibiting its Mental Battery service at the Work Style Reform EXPO 2025 Tokyo Exhibition [Autumn] in Makuhari Messe, to be held from September 10th to 12th, 2025.
The Mental Battery service is a stress solution platform that visualizes employees' invisible stress in real time. Through this service, we not only promote breaks based on data, but also promote employees' mental health, which has been difficult to see until now, and help foster a stress-free culture where employees can easily take breaks.
At the Work Style Reform EXPO, which will be held as part of General Affairs, Human Resources, and Accounting Week, you can see how the Mental Battery Service actually measures mental fatigue and suggests break times. MENTAGRAPH Booth Image (21-59) Please stop by our exhibition booth (21-59) and experience the ring, app, and dashboard of the Mental Battery Service, a next-generation mental care solution that achieves data-driven stress level management. A mini seminar will also be held at the booth to explain the service and introduce use cases.

After "Work Style Reform," it's time for "Mental Care Reform"
By wearing "Mentoring," which is equipped with a high-frequency measurement sensor, while at work, the app visualizes the individual's mental state, and a dashboard viewed by managers allows them to understand the mental state of the team.

~Device and function introduction~
<Measurement>
Employees wear a ring-shaped device called "mentoring," which collects information on their fatigue and stress levels in real time and with high accuracy based on blood flow (pulse rate), sweating, and body temperature.
<Visualization/Alerts>
The dashboard visualizes the mental fatigue and stress levels of individuals and organizations. Team managers can easily check the mental state of their team members and provide prompt mental care, such as understanding the situation based on one-on-one data. It is also possible to grasp the overall state of the team and compare it with other departments. Centralized management of employees' mental states contributes to improved productivity and stronger employee engagement, and helps promote health and productivity management.
<Promoting breaks>
Employees can understand their own mental fatigue and stress levels through a dedicated smartphone app, which automatically notifies them of appropriate break times.
