<Major reasons for gender pay gap in regular worker>

  • We have introduced a human resources system aimed at enabling everyone to play an active role regardless of age or background, with clear and differentiated evaluation and compensation tailored to their roles and performance. Compensation is the same for men and women, and any current salary gaps are due to differences in job duties, job grades, and age structure.
  • For managers, the introduction of a job grading system means that salaries are determined based on position. As a result, the ratio of the annual average salary of female employees compared to male is minimal at 93.7%, with each level of managerial hierarchy maintaining a wage ratio exceeding 90%.
  • The main factors contributing to the gap among non-managerial level employees (85.0%) are differences in length of childcare leave and utilization ratio of shortened work hours for childcare, as well as limitations on overtime work due to life events. In particular, the impact is significant in G3 (86.1%), where there are more employees taking childcare leave and working shorter hours. We have set targets for long-term paternity leave to encourage greater involvement of men in child-rearing. We are continuously working to raise awareness and improve the workplace environment, resulting in an increase in the average number of days of paternity leave taken by male employees. (2023: 21.4 days ⇒ 2024: 31.5 days)
  • To eliminate these disparities, we are focusing on ongoing efforts to promote women’s participation in management, such as proactively appointing female managers and supporting their career development.
  • Our goals and initiatives for promoting women’s participation in the workplace are detailed in “Section 2: Business Overview - 2. Approach and Initiatives on Sustainability.”
  • Under the new human resources system introduced in 2025, we have expanded the job grade system already in place for managerial positions to all employees. By combining this with a job posting framework, we have created an environment that encourages employees to actively design their own careers and take on new challenges, regardless of age or background.

Standards for Calculating Social Performance Indicators

<The boundary of calculation>
Chugai Group employees: Employees at all Group sites and facilities in Japan (including contract employees, part-time employees, temporary employees, employees on loan to our group)
Contractors: Employees of contractors in Japan (dealing with equipment and equipment maintenance contractors, etc.) who work together with Chugai Group employees at plants, research laboratories, and other business sites with hazardous operations.

<Calculation period>
January - December 2024

Lost-worktime Injury Frequency rate, Occupational incidence severity and Occupational Illness Frequency rate

Social performance indicator Calculation method
Lost-worktime injury frequency rate Number of people injured or killed in occupational accidents per 1 million work hours (resulting in at least one work day off, and an application for accident compensation insurance, but excluding accidents during commuting), showing the frequency of occurrence
Injury frequency rate = number of people injured or killed in occupational accidents / total number of actual working hours*1 x 1,000,000
Occupational incidence severity Number of days of work lost to occupational accidents (excluding accidents during commuting) per 1,000 work hours, showing the severity of the accident
Occupational incidence severity = number of workdays lost / total number of actual working hours*1 x 1,000
Occupational Illness Frequency rate Number of occupational diseases per 1 million work hours (calculated based on persons certified as occupational accidents) represents the frequency of occurrence of occupational diseases.
Occupational diseases are stipulated in Article 35 of the Ordinance for Enforcement of the Labor Standards Act in Japan.
Occupational Illness Frequency rate = number of occupational diseases / total number of actual working hours*1 x 1,000,000
  1. *1 When the number of actual working hours of temporary employees is unknown in FY 2023 and before, it is estimated by multiplying the number of such workers as of December 1 of the relevant year x 7.75 hours/day x working days. In FY 2024, all figures including temporary employees are calculated based on actual working hours.

Fatalities

Social performance indicator Calculation method
Fatalities The death of a worker arising from an occupational disease or injury sustained or contracted while performing work that is controlled by the organization or that is being performed in workplaces that the organization controls.
