Promotion System
DE&I Promotion Committee
Under the Sustainability Promotion Committee, we have established the DE&I (Diversity, Equity & Inclusion) Promotion Committee. The DE&I Promotion Committee is established at headquarters, branch offices, International Business Unit, and group companies to plan measures and monitor their implementation status in collaboration with relevant departments and labor-management, working together to resolve key issues.

Promotion of Female Empowerment
In April 2016, we established the Diversity Promotion Center (currently the Diversity & Inclusion Promotion Office) to create a workplace environment where diverse employees from diverse backgrounds can continue to work with vitality.
We are committed to fostering a workplace where women can thrive in their work by enhancing internal systems and implementing supportive measures that enable them to work comfortably, as part of our broader efforts to build a more inclusive society. In particular, we provide career support and develop environments that allow employees to continue their careers on-site through different phases of life, such as child-rearing.
We have formulated the Third Action Plan for the Promotion of Female Empowerment and have provided it on the Ministry of Health, Labour and Welfare's Database of Companies Promoting Female Empowerment.
