Kajima Group’s Material Issues

In July 2019, we looked at the relationship between the SDGs and the Kajima Group’s business activities, Medium-Term Business Plan measures, and other activities. We then grouped the results into seven categories of material issues for both addressing social issues and achieving sustainable growth for the Kajima Group.

We continued to regularly review the material issues and in 2024 conducted a full review while framing the Medium-Term Business Plan (2024–2026) and Kajima Environmental Vision 2050plus. We have partially revised our issues of materiality related to the environment as well as some other areas after considering the changes in social environment, opinions from external specialists, and input from our internal departments.

Determination of Material Issues

Based on the chart above, we identified issues that are important to the Kajima Group and have a major impact on society. We have condensed, reorganized and labeled these as seven material issues: four to which the Kajima Group can contribute through its businesses and three that form the basis for business sustainability
