The Lion Group has established the All Lion (AL) Safety, Health and Disaster Prevention Policy based on the shared basic philosophy that “safety is its absolute top priority.” Accordingly, it strives to ensure the safety and health of all Group employees and to clarify the Group’s overall commitment to establishing a comfortable and pleasant work environment.
The Group constantly works to strengthen its occupational safety and health management system. Within the domestic Group (the Company and its domestic affiliates), we operate in accordance with a system that combines disaster prevention measures with our Occupational Safety and Health Management System (OSHMS),”* which is based on Japan’s Ministry of Health, Labour and Welfare guidelines. Under this system, we strive to reduce potential hazards and risks, continuously maintain and improve workplace environments, create safer and more secure workplace environments and build related systems.
＊ A system for the organized operation and management of health and safety activities.
Under our Group-wide risk management framework, we have established the Safety, Health and Disaster Prevention Meeting, chaired by a Lion Group. This committee formulates and deliberates on measures to ensure occupational safety, facility safety and disaster prevention—including the improvement of the workplace environment, the prevention of health hazards and the maintenance and promotion of mental health—with the aim of enhancing safety, health and disaster prevention standards at every level of operations. We have also established a dedicated department responsible for health, safety and disaster prevention management. By enhancing cross-organizational coordination, we continuously advance initiatives aimed at risk reduction.
The Safety, Health and Disaster Prevention committees established at each domestic Group company in accordance with the Industrial Safety and Health Act play a central role in this effort. These committees incorporate feedback from employees at all worksites to identify risks—including those specific to each location—and work to implement improvements. We also strive to foster a consistent safety culture and raise safety standards on a global basis by working with our overseas Group companies on efforts that include sharing the All Lion (AL) Safety Philosophy and providing support for local health, safety and disaster prevention activities.
In 2025, there were no serious occupational accidents*1 within the Group resulting from work-related incidents or equipment failures.

Under the chairperson of the Safety, Health and Disaster Prevention Meeting, safety audits are systematically conducted at each domestic Group company. These on-site audits determine whether safety, health, and disaster prevention activities, safety management systems, and safety, health, and disaster prevention standards are being properly maintained and improved from an objective standpoint, with the aim of reducing the risk of accidents and disasters at our factories. In 2025, top safety audits were conducted at three factories.*
* Chiba Plant, Odawara Plant and Akashi Plant
The secretariat of the Safety, Health and Disaster Prevention Meeting immediately notifies all employees when an occupational accident occurs involving a Group member within Japan. This allows each business site to quickly assess the risk of a similar incident occurring, ensures that every employee stays on the alert for similar hazards and generally helps circumvent the occurrence of workplace accidents.
In recent years, “falls” have consistently ranked as the most common type of workplace accident and we have implemented the All-Lion Fall Prevention Action, a Group-wide initiative, in response. As part of this initiative, our “Innovative Approach to Reducing Fall Risks” project uses the physical function assessment app “KOKEN,” developed by Seiko IT Solutions Co., Ltd. alongside the participation of the Fangs, Lion’s official rugby team. This project was recognized in the Inter-company Collaboration Division of the FY2025 SAFE Consortium Awards, hosted by the Ministry of Health, Labour and Welfare, earning the Bronze Award.

SAFE Consortium Portal(The Ministry of Health, Labour and Welfare）[Japanese]The results of investigations of equipment accidents inform the systematic implementation of equivalent improvements in similar areas at all domestic Group production plants. For example, along with conducting inspections of outdoor tanks used for hazardous material and oil storage at all of the Group’s production plants, based on lessons learned from recent equipment leakage accidents, we have also reviewed equipment maintenance plans.
Furthermore, to promptly identify the risk of leakage due to age-related deterioration, we have introduced a new non-destructive inspection method (inspection of insulated piping using a neutron moisture meter) and are working to detect piping corrosion at an early stage.
We will continue to further enhance the operation of the change management* process and remain committed to improving equipment safety technology and thereby reducing accident risks in the medium and long term.
* Management activities to prevent risks associated with changes in equipment and operating conditions
All domestic Group production plants conduct joint disaster prevention drills with local public fire departments to prepare for large-scale disasters. In doing so, we not only enhance our emergency response capabilities, but also actively strengthen cooperation with local disaster prevention agencies and ensure a disaster prevention system that works in harmony with the local community.
The domestic Group prepares for emergencies by ranking potential scenarios and developing corresponding manuals outlining action plans for each. In particular, we have identified large-scale earthquakes, heavy rainfall from linear precipitation belts, and other natural disasters to be corporate risks. Therefore, in addition to disaster drills conducted by each business site that specify detailed response details and action standards according to the scale and damage of the disaster, we conduct Company-wide joint disaster drills to promote activities aimed at risk mitigation.
In addition, to accommodate diversifying work styles, we have established a disaster preparedness system that integrates in-person and remote locations in preparation for large-scale natural disasters.
Anticipating an increase in the frequency and severity of natural disasters and the further diversification of work styles and employment patterns, we will further upgrade our disaster response capabilities. At the same time, through safety confirmation drills and lifesaving courses, etc., we will also continue to improve each employee’s ability to respond to emergencies while strengthening our disaster prevention activities that contribute to local communities.
To prevent occupational accidents, we must further enhance our safety management system and heighten every members’ occupational safety awareness. Domestic Group companies systematically implement safety awareness training via e-learning and safety training at each business site. In 2025, there was a 100% implementation rate of safety education and training in each department, and the employee participation rate was 98.3%.

Under a 34-year program to raise awareness of the importance of safety among all domestic Group employees, the Lion Group has designated June 26 of each year as “Lion Safety Day.” On the day of the event, employees are reminded of the importance of safety through a message and lecture delivered, respectively, by the president and the chairperson of the Safety, Health and Disaster Prevention Meeting and broadcast to all production plants throughout the entire domestic Lion Group during a Company-wide morning assembly. In conjunction with Lion Safety Day, we are also developing various safety awareness initiatives, such as safety slogans and safety awareness surveys for all employees, with the aim of fostering and solidifying a safety culture.
Domestic Group companies provide ongoing support to overseas Group companies based on their circumstances and strives to enhance their safety, health and disaster prevention systems.
In 2025, we supported the implementation of safety training by an external organization at the production plant of Lion Corporation (Thailand) Ltd., taking advantage of the Asia Occupational Safety and Health SAKURA Project, a project subsidized by the Ministry of Health, Labour and Welfare.
