Work-Life Balance

Work style reform

In 2021, our company formulated a "Work Style Reform Declaration" with two pillars: "Promoting comfortable remote work" and "Creating new value with tools that adapt to change," with the aim of improving productivity and fostering autonomous talent. Since then, we have been promoting work style reform while exploring the optimal form, with the goal of improving productivity through a review of work processes, maintaining physical and mental health, and improving work-life balance.

  • Promoting policies to diversify workplaces and working hours.
    • Remote work system (implemented in 2024)
      By moving away from location-constrained work styles, we can attract and retain talented individuals who live in remote areas.
    • Remote work from family residences both domestically and internationally (implemented overseas in 2023 and domestically in 2024).
      We aim to improve work-life balance by creating an environment where employees can choose the work style that best suits them.
    • Flexible working hours for part-time employees (implemented in 2023)
      This system allows part-time employees to choose their working hours flexibly, enabling them to balance work and private life and work efficiently.
    • Addition of part-time work options (implemented in 2026)
      We have made it possible to choose a shorter work schedule not only by reducing the working hours by two hours from the regular schedule, but also by reducing them by one hour, allowing for more flexible work arrangements.
  • Review and revision of policies
    By reviewing the work style policies we have implemented so far, we will identify challenges and proceed with revisions and consideration of further measures to move towards our desired future state.

Optimization of working hours

For our company, optimizing the total actual working hours of our employees has become a particularly important issue in recent years. However, the important thing to remember when addressing this issue is that we must not simply aim to reduce working hours.
The true aim is to foster the growth of all employees into autonomous individuals through these initiatives, thereby promoting physical and mental health, work-life balance, and diversity.

As part of our efforts, we have established work rules that include setting fixed working hours, prohibiting late-night work and overtime exceeding 5 hours per day, and ensuring a 10-hour work interval. We also continue to encourage each employee to take stock of their own tasks and think not about "what to reduce," but rather "what to focus on."
Furthermore, we regularly conduct educational videos on working hours and work rules, as well as quizzes for all employees of the group, to ensure that everyone is thoroughly aware of and adheres to proper working hour management practices.
Starting in June 2025, a new rule to prevent excessive working hours will be established, which will, in principle, prohibit working overtime for more than a certain amount of time, in order to further reduce the risk of health problems.

Relationship with labor unions

Providing excellent products and services to contribute to society is a major mission for both management and employees. Based on mutual trust and cooperation, each party fulfills their responsibilities and strives to create a better workplace.
Furthermore, as a forum for labor-management communication, we hold labor-management consultation meetings four times a year at both the individual business unit level and the company-wide level. These meetings provide an opportunity for active exchange of opinions on various issues, such as the company's situation and improvements to the working environment, and for the formation of labor-management agreements.

Creating an environment where diverse talents can thrive

As part of creating an environment where diverse talents can thrive, our company is committed to supporting work-life balance. In recent years, we have particularly focused on increasing the rate of male employees taking childcare leave, actively implementing initiatives such as sharing stories of employees who have taken leave at internal forums, conducting work-life balance strategy seminars, and holding exchange meetings for employees with children. As a result, the rate of male employees taking childcare leave in fiscal year 2025 is projected to reach 82.56%.

Trends in the number of people using the leave of absence system
Number of people using the leave of absence system

We revised our previous system of reduced working hours, which was previously only available for childcare or elder care reasons, to a system with no specific requirements. In October 2023, we also revised the system to allow employees on reduced working hours to work flextime, thereby expanding the range of work options available to our employees.
Furthermore, the flexible working hours system no longer has a core time, and from April 2022, it became possible to take leave in hourly increments, making it even more flexible to work.
Furthermore, starting in February 2024, we have introduced a remote work system that enables employees to continue working even from remote locations where commuting is difficult. Employees who need to change their place of residence or for whom changing their place of residence is difficult due to family circumstances (caregiving, childcare, etc.) can now work from a residence far from their workplace.
