Human Resource Development / Organizational Development

Our Human Resource Development Philosophy

Mitsui & Co. and its group companies have a long history and tradition of focusing on human resources and has worked consistently to develop and deploy talent capable of contributing to society. This commitment is recognized even outside of the company and has earned it a reputation expressed in the words “Mitsui is people”.
As a company determined to contribute to society by realizing the management philosophy of Mitsui & Co. and its group companies, we believe that our greatest priority is to develop human resources by enhancing the potential of every individual.
Mitsui & Co.’s approach to human resource development centers on on-the-job training (OJT) in frontline work situations. However, Mitsui & Co. HRD Institute supports and complements OJT-based human resource development by expanding and enhancing off-the-job training (Off-JT). We support human resource development and organizational development in various ways, including the planning and administration of educational and training programs, primarily for people working for Mitsui & Co. and its group companies around the world, and the provision of language services.
