Human resource development
Acquiring the knowledge necessary for one’s duties, honing technical skills, and developing the ability to adapt flexibly to changes in the business environment are all essential to career development. Based on our “Human Resource Development Plan” that sets out our talent development policy, Kumagai Gumi undertakes a variety of initiatives with the aim of developing human resources under the idea of “Enrich the self, create the future, and support people.”
Our corporate philosophy structure and vision for human resources

Support for certification and outside education
We encourage the acquisition of official qualifications such as Professional Engineer and 1st-Class Architect. For those preparing for exams, we provide support such as supplementary lectures and mock examinations to foster self-driven skill development.
Communication in personnel evaluations and execution of work
We conduct goal setting interviews at the beginning of the term, progress confirmation interviews at the mid-point of the term, self-evaluation confirmation interviews at the end of the term, and finally an interview on evaluation results for providing feedback. Employees may submit their preferences regarding future job assignments and skill development to the Human Resources Dept.
Achieving high training participation rates
At the time of training, in addition to the information provided to the trainee themselves, the general manager and supervisors connected with the relevant division and department are also notified in advance as part of efforts to create an atmosphere conducive to participation in training.
