Promotion of Health and Productivity Management

Promotion of KENKO Investment for Health

Prior to implementing mandatory retirement at age 65, effective from April 2019, Rengo formulated the Rengo Good Health Declaration in January 2019 to maintain and improve the health of employees and their families. We are promoting day-to-day healthy living and creating safe, secure workplaces so that everyone can enjoy healthy and active work and private lives throughout their entire lives. We have set up a Good Health Committee and Plant/Mill Good Health Committees and are expanding the priority measures of the declaration companywide. The Good Health Committee is composed of the company, labor union, and health insurance association. The Plant/Mill Good Health Committees consist of general managers of general affairs departments of the divisions and plants/mills, along with two Good Health Leaders (one each from the company and the labor union).

Actions to Promote Good Health

Since FY3/2020, Radio Taiso (radio-guided calisthenics) facilitated by specialized instructors and health promotion lectures have been conducted companywide. Leaders in health promotion have actively led efforts to provide instruction and explanations to ensure that Radio Taiso is performed properly, promote smoking cessation, and encourage communication by gathering opinions and reaching out to others. In addition to improving individual health consciousness, these activities lead to better workplace safety and productivity. In FY3/2025, approximately 50 employees, including managers from general affairs departments at divisions throughout Japan, took the Women’s Healthcare Certification^®: Women’s KENKO Investment for Health Promotion Officer examination to acquire accurate knowledge of women’s health issues and to become able to appropriately respond to various consultations from women.

Actions to Support Mental Health

To help employees maintain and improve their mental health and continue working comfortably, Rengo supports the mental health of its employees through internal training and by setting up internal and external consultation hotlines. Since 2010, both management and labor have recommended that employees take the Mental Health Management Exam Class II (Line Care Course) for acquiring knowledge and coping skills necessary for mental care in the workplace, and 256 employees have passed so far (as of June 2025). In 2012, we documented our initiatives in the form of the Plan for the Promotion of Good Mental Health, which was rolled out companywide. In 2014, we established rules for a gradual return to work so that those taking a break due to mental health issues can smoothly return to the workplace. We also aim for a 100% rate of undertaking stress checks, and strive to improve employee engagement by enhancing the workplace environment.

Actions to Create Congenial Workplaces for Everyone

As the work style reform movement to address long working hours has been taken up by the national government, Rengo has been implementing an initiative since 2015 to reduce total hours actually worked by improving total factor productivity (TFP). By analyzing the various factors behind productivity, we are working to raise productivity while also being conscious of technological innovations, as well as people’s work styles and state of mind. Labor and management are united in reducing overtime hours and encouraging employees to take paid annual leave. As a result of raising awareness and making improvements to the work environment, the percentage of paid annual leave taken in FY3/2025 surpassed the target of 65%. We are making progress in further reducing total actual working hours, including raising the annual paid leave target.

Initiatives to Improve Total Factor Productivity (TFP)

Currently, working hours in the corrugated packaging industry are considerably long compared with other manufacturing industries, and the rate of paid annual leave taken also tends to be low. Improvement is urgently needed to create more worker-friendly workplaces. To address this, the Japan Corrugated Case Association is promoting initiatives to reduce actual working hours by improving total factor productivity (TFP: Total Factor Productivity). The association encourages member companies to analyze all productivity-related factors and pursue innovation, supporting these activities with the goal of shortening working hours and achieving an annual total of actual working hours equivalent to the average level in the manufacturing industry.
As a leading company in the industry, Rengo will take the initiative in these efforts, reduce excessive working hours, and focus on creating an environment where young people can pursue their aspiration and build fulfilling careers.
