Basic stance and policy
Safety and health first
As a global company, a critical management issue for us that strictly applies at every one of our locations is the building and maintenance of a workplace where everyone can perform safely and healthily.
Aisin has established the AISIN Group Safety and Health Policy and The AISIN group Declaration of health based on the principle of “Safety and health first”, which applies at all times. We conduct various activities based on these policies and declarations.
Promotion Structure
Safety and Health Promotion Framework
To protect all individuals working on Aisin premises from work-related accidents, we have established the AISIN Group Safety and Health Committee, which is composed of the presidents of each Group company and promotes activities aimed at unifying policies and standards. Matters discussed are reported to and approved by each company’s Safety and Health Committee and then progressively rolled out to individual workplaces via members of lower-tier safety and health committees at the workplace level. Furthermore, initiatives are disseminated to Group companies through the Aisin Group Director Safety Conference, while also providing support for safety activities tailored to each company's specific needs.
Moreover, important matters discussed by the Safety and Health Committee are reported to the Board of Directors, which provides oversight.
Strategy
Group Safety Vision for 2030
We promote thorough measures to prevent recurrence and various initiatives to eliminate serious accidents and lost-time injuries, enhance safety awareness, and make safe behavior a habit.
We have established KPIs within the Group Safety Vision for 2030 and are working to create an environment where employees can work with peace of mind, remain physically and mentally healthy, and thrive.
Under our Materiality Issues, to lay a solid management foundation, we have set “A culture that prioritizes safety” as a KGI and “Zero serious accidents” as the corresponding KPI.

Occupational Safety and Health Management System
To support risk management and raise performance, since FY2021, we have operated an Occupational Safety and Health Management System across the entire Aisin Group, including on-site contractors.
By FY2026, 40 Group companies, including AISIN, have been certified for ISO 45001, an international standard. We annually assess risks and opportunities based on internal and external objectives and the needs of employees and other stakeholders. We prioritize the selected items, incorporate them into the following fiscal year's safety and health plan, and promote activities to achieve our goals. Based on the outcomes of our activities as well as other variables, management reviews are conducted. After clarifying our direction for the upcoming fiscal year, efforts are made to enhance the level of our initiatives.
ISO 45001 certification status (End-March 2026)
ISO 45001 acquisition rate*: 32%
OSHMS internal implementation: 52%

Other initiatives
Safety
Avoiding work-related accidents and preventing recurrence
In accordance with our core philosophy prioritizing safety and health above all else, we work to prevent initial and subsequent occurrences of occupational accidents while conducting on-site safety inspections based on direct observation as well as efforts to raise safety awareness. Group company leaders elicit information from the front line and work closely with employees to advance safety measure geared toward achieving a record of zero accidents. In the interest of a safe and healthy working environment, we prioritize safety and health above all else and will continue to rigorously and effectively promote safety.
Risk assessment (RA measures)
We systematically investigate the hazards and harmful factors associated with our equipment and work operations.
By identifying potential risks in advance and evaluating and addressing them, we strive to prevent adverse incidents before they occur.
Specifically, we continuously improve safety by conducting, verifying, and evaluating equipment RA for machinery and equipment, work practices RA covering routine and nonstandard operational conditions, and chemical substance RA for chemical exposure.
AISIN Group meeting to prevent the recurrence of specific accidents
When an accident with the potential to lead to a serious accident (a STOP6 accident) occurs, AISIN and its Group companies hold a company-wide meeting at the company, plant, or department where the accident occurred to inspect and discuss the accident site, thoroughly investigate the cause, and implement countermeasures to prevent similar accidents.
Through these activities, we are shoring up our safety mechanisms to fully prevent serious accidents within our Group.

Aisin Global Safety Standard (AIGSS)
Based on international standards and lessons learned from past accidents, Aisin has established the Aisin Global Safety Standard (AIGSS) as the equipment safety standards the company must uphold. Using this standard, the Process Design Department, Manufacturing Department, and Safety Department identify equipment risks and implement countermeasures to promote the creation of safe and secure equipment and work practices.
Core equipment safety standards hierarchy
Safety awareness measures
Based on lessons learned from past accidents, we promote groupwide measures to instill understanding of the 18 Iron Rules for Preventing STOP6 Accidents. By having every employee maintain 'everyday awareness' and 'attention to abnormalities' and adhere to these basic 'iron rules,' we work to prevent accidents and raise safety awareness.
18 Iron Rules for Preventing STOP6 Accidents
Safety and Health training
Aisin has established a Safety and Health Education Center that plans and operates three skills-training courses authorized by the prefectural Labour Bureau and 24 in-house training courses (special training and internal safety education) based on laws and internal rules, while also promoting the acquisition of qualifications.
Through high-quality safety and health education and the systematic development of personnel qualifications, we work to raise each employee's safety awareness and cultivate staff who reliably comply with the rules.

AISIN Densho-kan (education center)
Driven by the desire to ensure past events are not forgotten and prevent the recurrence of failures, the Group established the AISIN Densho-kan to share lessons learned from past accidents and fires affecting the company.
In the safety domain, we instruct visitors to our facilities on the importance of safety, invoking our core principles, accident case studies, and other materials to recreate in detail the causes and consequences of accidents through case-study panels and CG video illustrations.
With regard to fire prevention, we exhibit actual equipment from the time of the Kariya Plant fire of February 1, 1997 and discuss lessons learned from the fire so that the incident is never forgotten. By showing the true horror of accidents and fires and keeping memories of these incidents alive, we aim to heighten safety awareness and enable our staff to protect themselves and their colleagues.
Safety instructors
Aisin has introduced a safety instructor system to implement safety guidance based on the principles of “GENCHI GENBUTSU GENNIN”(Get to the actual place, see the reality for ourselves and identify the facts.). Safety Instructors, trained as “guardians” with special safety promotion expertise through a 107-hour, 35-course program, support the promotion and management of safety across all workplaces within our facilities. The instructors work closely with employees in the field to neutralize potential hazards early and prevent accidents before they occur.
In the execution of their duties, our safety instructors promote activities to eradicate unsafe conditions and actions and, thereby, insulate their colleagues as well as their families and loved ones from potential grief.

Safety and fire prevention activities for construction contractors
We are committed to creating a safe and secure working environment for contractors operating within Aisin facilities.
(1) AISIN Group seminars on a safe environment for construction work by external contractors
We hold seminars addressing safety, the environment, and fire prevention for external contractors and those who procure their services. They are held before consecutive-holiday periods (spring, summer, and winter), when external construction contracting increases.
(2) Step-Up Training & Safety Inspections
Aisin has introduced step-up training, a program for construction supervisors that was implemented since 2011 and upgraded to a formal requirement in 2019.
This training promotes construction safety management and the prevention of work-related accidents. Participants are instructed in regulations and management documentation to improve their ability to identify the causes of potential accident in advance and implement countermeasures. Participants learn concrete, practical methodologies covering planning and preventative measures, thereby promoting a safe and secure construction worksite.
In addition to overseeing the safety of construction sites and operations involving external contractors, we assess and remediate concerns we observe to creating a safe construction environment.
Participants completing step-up training
Safety and environmental activities for loading, unloading, and other contract work companies
Following a serious accident that occurred in July 2015, we are working to create a safe and secure work environment and ensure that no such serious accident occurs again.
(1) Safety information exchanges for on-site loading and unloading and subcontract work
We hold information exchange meetings twice a year (June and November) for workers involved with loading, unloading, and other contract work, as well as employees responsible for ordering such work.
(2) Other efforts at improvement
To ensure a safe work environment, we refine difficult-to-perform tasks and mitigate hazardous conditions at our worksites.
Industrial hygiene
Occupational health framework enhancement and prevention of health issues
Aisin aims to create a workplace where every employee can work energetically and be healthy. We are reorganizing systems and developing our staff to support sustainable occupational health management systems at each of our facilities These efforts include the proactive management of chemical substances at the worksite.
To advance occupational health, we establish rules and standards, implement and provide training for clear methodologies for management and operations, and work to protect on site staff from occupational afflictions.
Examples of initiatives
Maintenance and improvement based on working environment measurements
We appropriately manage organic solvents, dust, and other hazardous substances and assess worksites for such factors as heat and noise, acting on findings to create a more comfortable workplace.
Hazardous substances
n=359 (number of Designated Workplaces)
| Ⅰ | Ⅱ | Ⅲ | |
|---|---|---|---|
| Organic solvents | 182 | 1 | 0 |
| Particulates | 111 | 0 | 0 |
| Classified chemical substances | 64 | 0 | 0 |
| Lead | 1 | 0 | 0 |
Control class I: worksite management is in an appropriate state
Control class II: room remains for improving worksite management
Control class III: worksite management is not in an appropriate state
Regarding Control class II workplaces
Organic solvents
- Cause: insufficient local exhaust ventilation capacity
- Interim measure: use of gas masks
- Permanent countermeasure: revised cleaning cycles and improved equipment capacity (planned)
Workplace noise
n=1,272 (number of workplaces)
| Ⅰ | Ⅱ | Ⅲ | |
|---|---|---|---|
| Noise | 1,168 | 89 | 15 |
Control class I: equivalent sound pressure level of less than 85 dB
Control class II: equivalent sound pressure of 85 dB or above but level of less than 90 dB
Control class III: equivalent sound pressure of 90 dB or above equivalent
“Primary Causes of Exceeding Standards”
Control Class II
- Hammering sounds, press operation sounds, etc.
Control Class III
- Air blowers, workpiece drop sounds, etc.
“Preventive Measures”
- Implement management based on internal standards for workers in Control Class II and III, including earplug use and special health examinations
- Equipment countermeasures are being implemented sequentially according to plan
Prevention of musculoskeletal disorders
We promote more efficient workplace improvements by using Ergo-kun, an automated AI camera–driven analysis system developed in-house at Aisin, to visualize and evaluate workloads from the perspective of ergonomics (human factors).
Improvement theme: reducing strain when retrieving parts
Heatstroke prevention measures
Based on the Cool Work campaign published by the Ministry of Health, Labour and Welfare, Aisin appoints one heatstroke prevention officer from each workplace to manage preventative activities.
Annual plan
May
Heatstroke prevention officer briefing and study session
June
Heatstroke prevention education for all employees (video, live meetings)
July–September
Supervisor outreach activities (reminders after rainy season and holidays)
November
Activity review meeting (report on current fiscal year, exchange requests and opinions for the upcoming year)
Number of heatstroke cases (by cause)
In FY2026, the number of heatstroke cases increased due to record-breaking extreme heat. While human factors (individuals' inadequate health precautions) were frequently cited as causes, educational activities, early detection, and prompt response resulted in zero severe cases.
We promote measures to control heat at the source, such as thermal insulation and heat shielding, along with air-conditioning strategies aligned with carbon neutrality, to prevent heatstroke and create a comfortable workplace.
Fire Prevention
Efforts to Prevent Fire Recurrence and Minimize Damage
Twenty-nine years have passed since the Kariya Plant fire of February 1, 1997. Only about 20 to 30 percent of employees remember it firsthand, and management, including top executives, is concerned that the memory will fade over time.
To avoid repeating the same mistakes, we continue activities that convey the lessons learned and the messages and feelings we wish to share with employees, connecting these to each individual's awareness and actions.
Through our Densho-kan educational facility, we continue to preserve and pass on to future generations video recordings of firsthand accounts and other materials about past fire incidents.
AISIN Group Unified Six key elements of fire-prevention program
Starting in FY2024, we reanalyzed past fires and systematically catalogued the primary causes and compiled preventative measures for each—management of ignition sources and combustible materials, electrical fire countermeasures, duct management, etc.—into Six key elements of fire-prevention. We then mapped the fire prevention management status.
Through this activity, we are visualizing the management status level across the entire AISIN Group and promoting improvement activities.
＜Six key elements of fire-prevention＞
- Management of ignition sources and combustible materials (risk assessment and clarification of management issues)
- Hazardous material management (maintenance and inspections in accordance with laws and regulations)
- Strict enforcement of on-site hot-work rules
- Electrical fire prevention
- Duct management (clarification of inspection and cleaning rules)
- Initial fire suppression to minimize damage (four basic fire responses)
Fires may occur in the presence of an ignition source, combustible materials, and oxygen.
Enhanced management of fire-critical equipment
Equipment that may provide an ignition source is registered as requiring priority fire management (F-compo equipment*) to strengthen prevention controls. By clarifying management responsibilities related to fire prevention and ensuring compliance and maintenance, we aim to prevent fires before they occur.
F-compo equipment: a facility with fire-related components (ignition sources, combustible materials, and firefighting equipment) to be managed
Equipment represents a high fire risk due to the presence of ignition sources and combustible or flammable materials or posing a significant risk of major damage in case of fire.

Four basic actions during a fire
To minimize damage through the prioritization of human life and the promotion of swift initial firefighting efforts if a fire manages to occur, the Group has standardized four basic fire responses.
To ensure understanding of the purpose of these responses, we regularly hold workplace meetings and execute training using fire alarm simulations and fire extinguishers. Furthermore, in recent years, we have begun introducing VR fire extinguishers at some facilities to further enhance the training environment.

Fire-prevention awareness measures
Drawing on lessons learned from past fires, Aisin has introduced the 10 Iron Rules for Fire Prevention to strengthen fire-prevention activities and uses them in workplace education and other settings.
The 10 Iron Rules for Preventing Fires
Fire prevention surveillance
To maintain its fire-management framework and build it to a higher level, Aisin conducts fire-prevention surveillance through third-party inspections and evaluations. In FY2026, we expanded the scope of these activities to five Group company sites. We work to prevent fires and explosions before they occur by reliably implementing the improvements identified through this evaluation exercise.
