"Ningenmura Company" to create business through Human Resource Development and Company Development.

We believe that companies exist not just to pursue profits, but people who are encouraged to learn while being mutually beneficial "Ningen Hiroba". The foundation of that is, first of all, human resource development; we believe that the blooming of businesses useful for society will be accomplished as the company is making progress with all employees with the same mind and mission.
Each and every employee challenges towards the target every day, everyone gets involved with the company's evolution and innovation, and eventually the social existence value as a company increases. We aim to become such a "Ningenmura Company".

The company shall be a place where each employee self-improves with their co-workers and accumulation of each activity leads people as an irreplaceable existence in society.
