Sustainability

Health and Productivity Management

MITSUBA Group believes in the importance of creating a workplace where employees can work energetically for a long time so that each employee can lead a rich and fulfilling life. With this, physical and mental health is not the only thing that can be maintained, but the creation of a workplace environment and systems that provide peace of mind in life events (Marriage, childbirth, injuries, illnesses, etc.) are also promoted.

MITSUBA believes that the physical and mental health of our employees is an indispensable and valuable asset for the survival of our business.
Accordingly, in addition to analyzing the results of statutory health examinations and stress checks, we cooperate with the health insurance society to hold event such as optional seminars on topics that include ensuring sufficient exercise, maintaining and improving mental health, and preventing various illnesses. Regarding health checkups, employees are given opportunities to undergo health checkups based on the Rules of Safety and Health and Productivity Management.

MITSUBA Group Health and Productivity Management Policy

MITSUBA Group believes in the importance of creating a workplace where employees can work energetically for a long time so that each employee can lead a rich and fulfilling life. With this, physical and mental health is not the only thing that can be maintained, but the creation of a workplace environment and systems that provide peace of mind in life events (injury or illness) are also promoted.

Purpose and Promotion System of Health and Productivity Management

With the aim of enabling MITSUBA Group employees to lead healthy and fulfilling lives both physically and mentally, MITSUBA actively supports activities to maintain and improve health and raise health awareness. With that, we hold monthly meetings with the Health and Productivity Management Promotion Committee, which includes industrial physicians, industrial health staff, the labor union, and the health insurance union as participating members, and there we discuss how to encourage employees and such measures to be taken. Moreover, regular reports are made at management-level meetings, and the resolution of issues is speeded up by incorporating the intentions of top management.

Expected Effects of Health and Productivity Management and Connections between Management Issues

In addition to analyzing the results of mandatory health checkups and stress assessments, we collaborate with health insurance associations and labor unions to conduct seminars aimed at addressing physical inactivity, maintaining and improving mental health, and preventing various diseases.

In recent years, as part of our efforts to strengthen “Collabo Health,” we have introduced new initiatives, including health seminars for women that specifically address women’s health issues, as well as dental checkups during working hours at all workplaces.
