The Nissui Group recognizes employee health as a critical management issue and announced the Employee Health Declaration in 2017. Based on this declaration, we are implementing strategic initiatives that aim to “actively support both mental and physical health and create an appropriate work environment to improve productivity and generate new value". As a result of these initiatives, Nissui was certified as an Outstanding Organization of KENKO Investment for Health in 2018 for the first time in the fishery, agriculture and forestry industries. Furthermore, Nissui has been selected as a KENKO Investment for Health Stock Selection for five consecutive years since 2019 in recognition of its focus on employee health promotion through measures that utilize functional components derived from marine products. In addition, Nissui has recently been certified as a 2026 Outstanding Organization of KENKO Investment for Health "White 500."
The Nissui Group believes that one of the most important business foundations for its sustainable growth is human capital and it is based on the health of each and every employee. Accordingly, the President issued a message regarding KENKO Investment for Health in May 2026.

At the Nissui Group, we consider our employees to be our most valuable asset, and we want to see all employees be able to fully demonstrate their abilities. We also aim to improve the quality of life of our employees and their families by ensuring proper workplace conditions and by actively supporting both mental and physical health.
As a company that works with resources from the sea, we offer suggestions for healthy diets, try to maximize the use of functional components derived from seafood, and aim to contribute to the healthy lives of people everywhere, from our employees and their families to customers around the world.
In addition to following up with family members to alleviate anxiety and burdens in their health and personal lives to enable individuals to work with peace of mind, the Employee Health Declaration aims to create new value and enhance productivity by improving the workplace and systems environment so that diverse human capital of different genders, nationalities, and ages can work comfortably. In this way, a virtuous cycle can be generated in which the company can secure excellent human capital, and these excellent human capital can in turn help the company grow further. Nissui believes that the implementation of the Employee Health Declaration will shape the future of Nissui, and Nissui will place a high priority on investing in the initiatives associated with this declaration.
In implementing the Employee Health Declaration, we approach individuals and the workplace environment from the following two perspectives.
Main initiatives: Lifestyle improvement, exercise events, improvement of the EPA/AA ratio, enforcement of no smoking during working hours, mental health screenings (stress checks), cancer prevention measures, etc.
Main initiatives: Childcare and nursing care support, the employee benefits system, adoption of the cafeteria plan “N Café,” etc.
We regularly share and discuss health-related issues among the Human Resources Department’s Labor and Health Planning Section (secretariat), the Head Office’s Health Management Center (industrial physicians and occupational health nurses), business site occupational health nurses, and the Nissui Health Insurance Society, and jointly promote related initiatives. Going forward, we will continue collaborating with health promotion coordinators at each business location to support employee health and work-life balance, while fostering a workplace culture that is both comfortable and fulfilling.
We have established three items—smoking rate, obesity rate, and EPA/AA ratio—as KPIs for individual health promotion. These are important indicators reflecting employee health conditions based on regular health checkups. Deterioration of these metrics may lead to presenteeism (reduced performance despite attendance), absenteeism, or even employee turnover.
Among these, the smoking rate and obesity rate remain unfavorable compared to the national average. According to medical expense data from the Nissui Health Insurance Society, hypertension-related expenses are higher than the Society average. These figures highlight the urgent need for improvement.
Accordingly, Nissui has designated the smoking rate and obesity rate as priority focus areas, set goals referencing national averages, and continues to implement effective countermeasures.
The EPA/AA ratio represents the ratio of eicosapentaenoic acid (EPA)—a core component of Nissui’s Fine Chemicals Business—to arachidonic acid (AA) in the blood. This ratio is considered useful in preventing lifestyle-related diseases and is actively promoted by Nissui as an important health indicator. Since FY2016, EPA/AA ratio measurement has been incorporated into regular health checkups. The Company set a target value of 0.4 or higher— linked to cardiovascular disease—and has implemented various initiatives toward improvement.
For FY2026, Nissui has set new targets of EPA/AA ratio 0.6 for employees aged 40 and over, and 0.4 for those under 40, thereby enhancing age-appropriate health support.
To encourage these efforts, Nissui provides health incentives to employees who show improvement in their EPA/AA ratio. Additionally, a company-wide “Health Ranking” is published to visualize results not only by individual but also by department, thereby promoting greater health awareness company-wide.

To prevent health problem from smoking and passive smoking, Nissui is promoting initiatives to help smokers to stop smoking and to separate the smoking areas at the business locations.
We are carrying out a variety of initiatives to encourage smokers to quit. For example, we provide individual instructions by occupational health nurses at regular physical examination sites, measurements of carbon monoxide levels using “smokerlyzers,” and the distribution of nicotine gum samples. in addition to these, we support efforts to quit smoking by covering half of the treatment costs for employees who have successfully quit smoking through programs offered at hospitals. The President himself declared that he would quit smoking in January 2019 and nearly 30 employees followed suit by taking on the no-smoking challenge.
In 2018, the smoking areas of the head offices and branches were shut down, and smoking was banned in all company cars. The other business locations are also promoting the closing and reduction of smoking areas.
Since March 2023, Nissui has implemented a policy of “Going Smoke-Free during Working Hours 365 Days of the Year,” and continues to promote its enforcement and full implementation.

From May to July 2025, Nissui held the “Body Improvement New Contest,” a walking event that saw participation from 611 employees. Of these, 560 participants achieved over 150,000 steps during the period and the event was a blast. The average steps per participant totaled around 500,000, or roughly 8,000 per day, contributing significantly to building daily exercise habits. Post-event surveys revealed many positive responses, such as increased awareness of walking and reduced weight and waist circumference, suggesting that the event effectively encouraged enjoyable integration of exercise into daily life. In addition, an average weight reduction of 1.28 kg across all participants was observed between before and after the event.
In conjunction with the “Walk the World” charity event organized by the United Nations World Food Programme (WFP), Nissui conducted its own walking event, combining participation in the charity initiative with health promotion. By walking more than 5 km, participants became more aware of the importance of exercise while gaining exposure to global hunger issues. The initiative successfully combined themes of health and sustainability and received numerous positive responses from participants.
To improve employee health literacy, Nissui conducts annual Health UP events, health awareness surveys via e-learning, and health and productivity management comprehension assessments.
In FY2025, various company-wide health-related events were held across Nissui. Each event was tailored to the health issues faced by individual sites, and creative efforts were made to encourage employee participation. The online seminar "PMS and Chinese Medicine" for all female employees provided a valuable opportunity to deepen understanding of the usefulness and potential of Chinese medicine in managing discomfort associated with PMS. Activities at each business location included on-site massage and exercise events to improve leg strength, making them practical and easy to participate in.
In response to these efforts, participants commented: “My awareness of physical maintenance was improved,” “I learned more about women-specific health concerns and found it meaningful,” and “I feel my legs have become stronger.” These responses indicate increased health awareness and new personal insights. Nissui will continue to promote programs that foster individual health awareness and support actionable behavioral change.

Nissui is engaged in “Collabo-health (Note)” in collaboration with the Nissui Health Insurance Society (corporate health insurance society).
(Note) Collabo-health: An approach whereby health insurance societies and other insurers and employers actively collaborate to effectively and efficiently implement prevention and health promotion initiatives for enrollees (employees and their families) under clearly defined roles and a favorable work environment.
In cooperation with the Nissui Health Insurance Society, Nissui conducts regular employee health checkups and checkups for the prevention of lifestyle-related diseases, with an annual checkup rate of 100%. In FY2022, we introduced the “WellBis” health management support system, which allows health checkup results to be viewed on PCs and smartphones, thereby enhancing health management support functions. Nissui requires all employees with any abnormal findings in their checkup results to submit a “Re-inspection report” and are asked to see their family doctor, etc. The content of these reports is then confirmed by occupational health nurses. This“Re-inspection report”is available in four languages to facilitate reporting by employees whose native language is not Japanese.
In addition, as an effort to prevent serious illness, Nissui has created in-house health guidance guidelines and provide individual interviews and health guidance based on expert knowledge by occupational physicians or occupational health nurses for employees with high-risk health issues.
| FY2023 | FY2024 | FY2025 | |
|---|---|---|---|
| Management rate of high-risk groups | 95.9% | 98.9% | 97.2% |
From FY2020, Nissui switched from the conventional outsourced approach to the specified health guidance to one that is conducted in-house, essentially by nurses from the health insurance society. This has changed the awareness among the target group, and the implementation rate has increased significantly, partly because more people are receiving guidance and partly because the scheduling of initial interviews and so on has become more flexible. Furthermore, by having a nurse who is familiar with the company's health initiatives provide guidance, more effective guidance may be offered through the incorporation of these initiatives into the health-related instructions they give.
| Entity | FY2022 | FY2023 | FY2024 |
|---|---|---|---|
| Nissui Corporation | 71.5% | 67.1% | 66.7% |
| All enrolled entities (including those insured on a voluntary basis) (Note) | 69.1% | 66.3% | 65.4% |

Having many overseas bases, the Nissui Group is aware of the importance of responding to global health issues such as infectious diseases. In addition to conducting pre-assignment education on vaccinations, medical care, and health management for employees assigned to overseas bases, we make it possible for employees to receive medical examinations and checkups by overseas travel specialists both before and during their assignment in Japan every year; based on the results of these examinations, interviews with industrial physicians and health guidance are also conducted.
In Japan, Nissui also works together with the Nissui Health Insurance Society to provide mass influenza vaccinations and subsidize the entire cost. In addition, Nissui has incorporated rubella antibody tests into our regular health checkups to make it easier for individuals to receive them. For those individuals who were considered to have low levels of rubella antibodies, awareness and education was provided, and more than 40% of the recommended recipients received an antibody test during their regular checkups.
Once a year, Nissui conducts a mental health examination for its employees and is also making efforts to enhance mental health so that employees can engage in their work with a healthy mind.
Based on the results of these stress checks, Nissui provides feedback on organizational analyses to each department and establishes forums for exchanging opinions to solve problems. We are actively working on enhancing the workplace environment through consultations with occupational health nurses for high-stress employees and by offering a 24/7 external consultation service for anonymous support.
In addition, to prevent the occurrence of harassment, Nissui conducts harassment workshops (group seminars, e-learning, etc.), and has established an in-house Harassment Consultation Desk and a Harassment Consultation Hotline (external contact) to handle any problems that may arise.

In the course of implementing initiatives, Nissui are striving to improve on health challenges with a focus on three KPI categories (smoking rate, obesity rate, and EPA/AA ratio). Nissui provide opportunities for management to directly communicate their thoughts on health to employees, and for occupational health nurses to actively disseminate information and encourage employees to engage in health-related efforts. Through various measures taken by the sections in charge, each employee's health-related awareness level has been steadily increasing. In terms of the degree of improvement in actual business performance as a result of each employee becoming healthier, Nissui quantify presenteeism, absenteeism, etc., to confirm progress.

As part of our efforts to promote various health initiatives, we have established the “Regulations for the Handling of Health Information, etc.,” which stipulates the purposes, parties responsible for handling personal health information and the authority and scope they have in handling such information, as well as training for managers on how to handle the information properly.
As part of our employee health initiatives, Nissui has introduced “N Café,” a cafeteria plan-style employee benefits system. This program is designed to reduce anxiety and burdens related to health and personal matters for employees and their families, thereby allowing them to work with peace of mind. The benefit options are centered around “childcare, nursing care, and health,” and also include support for “personal development, asset formation, and life support,” helping promote work-life balance and daily well-being. Employees can select and use from a wide range of services tailored to their individual needs.
