Pentel manufactures and sells stationery and drawing materials as well as electronic devices such as touch screen panels and pen tablets. In recent years, the company has branched out into production of industrial robots and medical equipment.
Since 2019, Pentel has been promoting digital transformation (DX) to enhance its “manufacturing capabilities” by turning production plants smart through the introduction of IoT technologies. The aim is to increase manufacturing efficiency and improve quality. In 2021, the company expanded activities and established the Digital Shift Division, a unit in charge of DX of company-wide operations, but it faced challenges such as AI/IoT human resources development and development environment.
Pentel therefore adopted Asteria’s Gravio, which enables the development of AI and IoT solutions without coding, and launched a project led by staff members in the administrative department and junior employees with little experience in IT tools and system development. The project team began working to accelerate digitalization of offices using computer vision-enabled cameras and IoT sensors.
The project included remote monitoring of changes in temperature and humidity in a server room, which had been managed visually, and development of automatic monitoring solutions for key facilities using the image recognition feature of computer vision-enabled cameras. The solution has improved the efficiency of facility management operations and the security performance of the entire facility with computer vision-enabled cameras and IoT sensors. In addition, motion sensors and a door sensor have been installed in shared spaces such as meeting rooms and restrooms to visualize the status of their use.
Pentel is also considering building a remote monitoring and abnormality detection system for server rooms of factories in Japan by utilizing IoT and AI. In the future, the company intends to further promote DX throughout the company by expanding the smart office initiatives spearheaded by the Digital Shift Division to other offices and factories.

Business Plan of Gravio

As Japan is emerging from the COVID-19 pandemic, demand is growing for solutions to automatically monitor visitor flow in offices and avoid crowding in workplaces as more companies are gradually shifting back from telework to office work.
Asteria will continue to support the streamlining of facility management and implementation of advanced security measures in a wide range of post-pandemic business settings through the provision of Gravio, which enables the construction of solutions using AI and IoT in a short period of time without coding.
