    Calculated based on the provisions of the "Act on Childcare Leave, Caregiver Leave, and Other Measures for the Welfare of Workers Caring for Children or Other Family Members" (Act No. 76 of 1991). For FY 2019 to FY 2021, calculated based on the percentage of employees taking childcare leave. as stipulated in Article 71-4-1 of the "Ordinance for Enforcement of the Act on Childcare Leave, Caregiver Leave, and Other Measures for the Welfare of Workers Caring for Children or Other Family Members" (Ordinance of the Ministry of Labor No. 25 of October 15, 1991). In FY2022, in order to further promote the use of childcare leave by male employees, the ratio of childcare leave and our original leaves under Article 71-4, Item 2 was calculated. In light of the mandatory disclosure of the ratio of childcare leave taken and social demands for longer periods of childcare leave, in FY2023, the method was changed to calculate the ratio of childcare leave taken under Article 71-4-1, not including our original leaves. If the FY2022 is calculated excluding our original leave in accordance with Article 71-4, Item 1, the figure would be 39.9%. In each fiscal year, calculated including employees who are transferred to other companies, and excluding employees temporarily transferred to KDDI.
