About us

“Formation of a new computer system architecture” based on the fusion of Information and Electrical/Electronics, and “Solution of various social problems” such as energy exhaustion issues and cyber security issues are our missions.
Our goals are to explore the ideal form of “Cyber-Physical Computing”, which processes large amounts of data generated in the real world with high efficiency, and develop applied technologies for practical use with utilizing it in the real world.
