Decision-making processes and structures

The following three items have been established with respect to the structuring of the plant’s safety culture:

1. Greet your guests properly
2. Keep your appearance neat and tidy
3. Be sure to point and call properly

With respect to the plant’s safety, environment and quality policies, such are established in accordance with corporate policy. Concerning their orientation, such is decided through the meetings system.

Consideration of human rights by suppliers

The training session was held online in August 2024 and covered the following eight topics: 1) "Mid-Term Management Plan (YX2026)," 2) "Review of Materiality and Respect for Human Rights Initiatives," 3) "Carbon Neutrality Overview," 4) "CSR Procurement Guideline Revision," 5) "Compliance with Competition Law/Antimonopoly Law," 6) "Carbon Neutrality (SCOPE 3)," 7) "Information Security," and 8) "Risk Management."

Complaint resolution

There were no reports submitted to the Corporate Compliance Department, and no consultations requested.

Creating a safe and healthy workplace environment

Based on the recognition that the basis of corporate activity is assuring the safety and health of both our employees and those of cooperating companies, Occupational Safety and Health Management System (OSHMS) certification in accordance with Japan Industrial Safety & Health Association (JISHA) standards was obtained, and safety and health management has been implemented. This was done as a means by which to realize a safe, comfortable, and healthy workplace.
As a future company-wide plan, we are considering a mid-term transition to ISO 45001 (Occupational Health and Safety Management System), and this plant will be preparing for the switchover in October 2025.
In addition, each section is conducting risk assessment and risk reduction activities for existing facilities. 12 risk level IV and V cases were addressed in FY2022.
Regarding Risk Level III, we implemented 98 countermeasures in fiscal year 2023 and 65 in fiscal year 2024. We will continue to implement countermeasures in 2025.

Circle activities

We reduce all kinds of losses such as reduction of equipment breakdowns, quality defects, and improvement of workability. And, circle TPM improvement activities are being conducted to allow employees to make their own workplaces more comfortable and easier to work at. We are working to vitalize these activities through the holding of events including regular announcements on the results of improvements and bulletin board contests.

Human resources development and training

Work training is undertaken by our assignment of more senior workers to instruct both new hires and fixed-term employees. This one-on-one training increases individual skill levels because training results can be reviewed and revisited.
In addition, veteran employees systematically provide guidance on employee skills to ensure that product manufacturing skills are passed down from generation to generation.

Promotion of employment of people with disabilities

To promote employment opportunities, we visited a nearby special needs school to share information and hosted a work experience placement for one student in June.

Work-life balance

Two days a week, Wednesdays and Fridays, have been established as days with specified hours for leaving work.

Environmental data

Reductions in greenhouse gas emissions

Greenhouse gas emissions

Greenhouse gas emissions have been gradually decreasing since fiscal 2010.

Effective use of resources / Reduction of waste

Waste output

From fiscal 2006, we have continued complete zero emissions.

Waste landfill

In fiscal 2007, we achieved a recycling rate of 100% and we have maintained that rate since.

Water usage

The plant uses 400,000 tons of water a year.
Sources consist of underground water of about 90% and city waterworks of 10%.

Measures for discharge into water, air and soil

Data related to water contamination

The plant discharges about 430,000 tons of wastewater a year into the Sonobe River.

• Ibaraki Prefectural Ordinance and Environmental Protection Agreement with Omitama City
• Discharge point: Sonobe River

Soil contamination

We conduct groundwater analysis (shallow well) once a year and confirmed that the standard values were within the laws and the ordinances of Omitama City.

Air pollutants (NOx, SOx)

Measurements are conducted twice a year, and we have confirmed that the results are within the standards set out in all laws and in Omitama City Ordinances.

• The Air Pollution Control Act and Environmental Protection Agreement with Omitama City.

Reporting on chemical substance management status (Pollutant Release and Transfer Register (PRTR) Law compliance)

The Ibaraki Plant verifies whether secondary materials and auxiliary materials contain chemical substances subject to Safety Data Sheet (SDS) requirements, and in the case of substances where the amounts handled exceed the thresholds specified by the PRTR Law, annual reports are submitted to the national (or prefectural) authorities and safety impact assessment is performed.
Regarding the handling of substances pursuant to the PRTR Law, please refer to the Safety Evaluation Table of Domestic Production Bases.

Noise reduction

Noises are measured at 15 places on the border of the plant premises once a month. We can confirm that the results are within the standards set out in Omitama City Ordinances (below 55db).

Preventing pollution

So as to prevent risks to the environment, once a year we conduct drills and tests in response to predicted emergency scenarios (such scenarios include oil leaks occurring from heavy oil storage tanks and solvent cans being upset during transportation, etc.).

Industrial Waste Reduction Initiatives

To reduce industrial waste, we promote activities to reduce product and semi-finished product scraps and waste separation mainly by each process manager. We are working to reduce the amount of waste by recycling waste plastic generated during the manufacturing process and reusing some of the waste secondary materials as packaging materials.

Alleviating and responding to climate change

As energy saving activities, we are promoting the use of LED lighting, improvement of air conditioning efficiency by adopting MiRACLE coils, and horizontal deployment of heat insulation and heat retention.
We also conduct energy conservation patrols every month and continue to make repairs mainly to air, steam, and water leakage points.
During Energy Saving Month activities, all employees participated in energy saving promotion activities, making suggestions and improvements related to energy waste.

Environmental protection, and recovery of natural habitats

Concerning the Sonobe River into which discharges from this plant flow, biodiversity protection surveys have been conducted at a frequency of two times a year. During these surveys, we have monitored water quality, aquatic life, plants and birdlife, etc. We have also taken steps to eliminate certain species of introduced plant and aquatic life.
In addition, starting in 2019, we have organized a new "Survey on the Living Environment of the Grey-faced buzzard (Butastur indicus) " to survey the vegetation and small animals (amphibians and reptiles) in the plant, focusing on the Grey-faced buzzard, which is as a Vulnerable, as one of the indicators for environmental conservation.
With the cooperation of the Omitama Wildlife Society and the Wild Bird Society of Japan, Ibaraki Prefecture, we will continue to exterminate and monitor invasive alien species three times/year.
The company continued these activities, receiving recognition for its efforts with the ABINC Excellence Award in April 2023. In October of the same year, the company achieved the Natural Coexistence Site (OECM) certification, a first for the Yokohama Rubber Group.

Thorough statutory compliance

Submitted an internal audit under the Subcontract Act by the Materials Procurement Department. All contact staff participated in an online seminar on subcontracting transactions sponsored by the Ministry of Economy, Trade and Industry to deepen their awareness of legal requirements.

Consideration of supplier labor, safety and workplaces

Business dealings are conducted that are fair, transparent, openly competitive and suitable.

Thorough compliance

The company is actively promoting employment opportunities for senior citizens in the local community. Currently, five individuals from the Silver Human Resources Center are working at the company.

Regional contributions

We donated a total of 117 tree seedlings to Silva, a non-profit organization, in April and November. These seedlings are being used for planting and replanting activities in the Shonan Village "Forest Wandering" project.
In December, we donated 82 tree seedlings free of charge to Sango Kanto Co., Ltd. for their tree planting event.

Discussion for local residents regarding our activities to help safeguard biodiversity

Although we had planned to hold a meeting with local residents to discuss biodiversity conservation activities, we decided to hold the meeting in writing, considering the safety of local residents as our first priority.

Relationship with local societies
