Work-life BalanceSustainability

We aim to ensure that all our employees, both men and women, show their abilities to the fullest in manners that are appropriate for various life events. We have established a Flexible Working Hours System without core time, as well as holidays and paid leave programs, so that employees raising children or providing nursing care to their families can continue working while achieving a balance between work and family. We also provide employees on Maternity Leave or Childcare Leave with support for education/training so that the period of their leave will not be a blank period in their career trajectory.

Introduction of telecommuting

We have already introduced flexible working hours without core time and hourly annual leave. In addition, telecommuting was introduced in March 2018. In April 2019, regulations on telecommuting were expanded eligibility to any employee who can work from home, as well as employees who are caring for a child or parent. Since July 2021, we have abolished restrictions based on length of service and eased weekly restrictions on the number of telecommuting days. We aim to maximize the abilities of individuals through flexible and diverse work styles that are not bound by location or working hours.
