Overall Disclosure Profile
Idemitsu Kosan Co.,Ltd. links its human capital strategy to enhancing frontline capabilities, internal and external collaboration, and value creation, while outlining paths toward financial outcomes targets for each business area. In FY2025, it held action-guideline briefings across all 60 departments and offices and estimated approximately 1,300 advanced practitioners.
Its proprietary employee engagement indicator was 70%, below target. The filing explains that understanding of the guidelines has not sufficiently translated into daily behavior and identifies heavy workloads as an issue. Its framework and issue analysis linking human capital initiatives to work outcomes are specific, but disclosure of achieved work outcome volumes and calculation methods remains limited.
Scores by Assessment Item

Assessment Scope & Disclaimer
This assessment is based solely on information disclosed in the company's Japanese-language Annual Securities Report filed through EDINET.
It does not assess the human capital initiatives a company actually implements or the company's human capital capabilities themselves.
Items for which no disclosure was identified in the Annual Securities Report receive no points, regardless of whether the company actually implements the relevant initiatives.
This English-language assessment is a translation of the original Japanese assessment and is provided for convenience. In the event of any discrepancy, the Japanese assessment prevails.
