Quality Management

Kuraray’s Approach to Quality

The Kuraray Group’s approach to quality is rooted in the realization of the Kuraray Group’s Mission: “For people and the planet—to achieve what no one else can.”
 Our products and services can only be valuable when the values are recognized and accepted by customers. In other words, Kuraray’s concept of quality is “customer satisfaction.”
 In order to provide products and services that achieve customer satisfaction and contribute to society, we believe that it essential not only to pursue the performance and quality of our products and services but also to consider multiple aspects, including safety, environmental impact, and sustainability.
 For this reason, it is necessary to conduct comprehensive quality management in both manufacturing, such as production and development, and in sales, distribution, storage, value chains and so on, and we are promoting initiatives with the participation of all employees.

Quality Management

The Kuraray Group clearly states in its internal rules for quality assurance and product safety that the officer in charge of the Corporate Sustainability Division supervises quality assurance for the Group.
 While respective business divisions, which know their products well, take responsibility for quality assurance and product safety, the Corporate Sustainability Division as a corporate function systematizes quality management at respective business divisions with a view to ensuring continuous improvement. It is also in charge of conducting quality audits for respective business divisions from an objective viewpoint to confirm the reasonableness of quality assurance operations.
 Respective business divisions and the Corporate Sustainability Division have regular meetings regarding quality to share information and work together to ensure and improve quality.

The Kuraray Group sets out that “we will constantly develop and provide safe, high-quality products and services” in our Corporate Statements, and have formulated the Kuraray Group Global Quality Policy to make our corporate stance toward quality clearer.

Kuraray Group Global Quality Policy
“We contribute to the society by supplying safe, reliable and high-quality products and services.”

We vow to provide safe high-quality products and services with a sense of responsibility and pride, and contribute to improved natural environments and living environments with a view to realizing a sustainable society.
 To that end, each one of us will engage in improvement activities continuously to pursue the creation of value to enhance customer satisfactions with better understandings of demands of laws and regulations, society as well as needs of customers.

We also set “annual action plans” regarding points that should be focused on to improve awareness toward quality in the employees of the Kuraray Group and provide products that offer greater satisfaction to customers.

We ensure correct operations to support implementation of the Kuraray Group Global Quality Policy. We have established the Kuraray Group Product Safety Regulations, which clarify requirements for product liability, chemical substance management, and quality management, as well as various subsets of internal rules and detailed regulations.

Quality Assurance Activity

Quality assurance activities of the Kuraray Group include 1) systematized activities with ISO as a basis, 2) those carried out by respective business divisions and departments on their own (flexibly), and 3) those carried out jointly by the Corporate Sustainability Division and respective business divisions.
 With regards to ISO 9001, which serves as a foundational structure for our Quality Management System (QMS), certifications are primarily obtained by each production site, which develops a framework for quality assurance based on ISO9001 and carries out quality management and quality assurance activities on a daily basis.
 We have also obtained certifications for ISO13485 (QMS standard for medical devices), IATF16949 (QMS standard for the automobile industry), and others, depending on our businesses.

Quality improvement activities carried out by each business division or department include soushin katsudo (innovation activities) conducted by each division at each production base. Good practices for quality improvement activities are shared through in-house reporting meetings, quality conferences, and quality reporting meetings at internal companies and divisions.

In addition to these activities undertaken by each business division or each department, we have initiatives in place that aim to upgrade quality management for the entire Group with the collaboration of the Corporate Sustainability Division and respective business divisions. Since 2020, we have been considering the introduction of our Quality Management System (to reliably store and trace quality data, visualize quality information, and to enable, direct storage from analytical equipment and linkage with a backbone system) to standardize the quality management workflow and prevent human errors such as typographical errors. We started operation at some of our business divisions in 2023 and have also started to expand operation at our global business units in 2024. In the future, we will continue to promote the introduction of our Quality Management System globally.
 In 2024, we are also revising internal regulations on quality assurance and verifying the methods of managing certified products that were found to have problems at other companies. We aim to improve internal quality awareness, including not only those in charge of quality assurance and quality control, but also those in charge of production, sales, and development.

We believe that it will become increasingly important to ensure the quality assurance spanning the entire value chain, from the purchase of raw materials to the manufacture of products and their consumption in the future. Aiming to further enhance the reliability of our product and service quality for customers through the participation of all employees involved in business activities, we will continue to provide products and services through these activities in 2025 that achieve greater customer satisfaction.

Quality Assurance Education

The Kuraray Group has revised the Kuraray Group Quality Handbook, which summarizes our approach to quality in 2024, and published it for our employees. This Quality Handbook prescribes the following five basic key items commonly applied to all members working for the Kuraray Group:

1 That everyone participates in striving for quality (participation by everyone)
2 That employees satisfy the requirements for a given process before going on to the next process (building quality into processes)
3 That everyone bases his or her conduct on facts (fact-based management)
4 That employee conduct conforms to the idea of genba (actual place), genbutsu (actual products), genjitsu (actual facts), genri (theory), and gensoku (fundamental)
(the “Gogen” principle)
5 That employees constantly strive to improve quality (continuous improvements)

Together with this quality handbook, employees receive basic education on the quality handbook in an e-learning format. Through this type of basic education, we are committed to anchor awareness in employees that each of them plays an important role in customer satisfaction. We will continue to have everyone in the Kuraray Group work on daily operations to realize “customer satisfaction” rooted in those five important items.

At the same time, as a more practical type of education, we are focusing on in-house seminars aimed at raising the level of managers in charge and staff in quality assurance. In 2024, we held an in-house seminar in which an outside presenter spoke about the theme of “Avoiding the Quality Fraud and Misconduct Trap: The True Causes of Fraud and Misconduct, Preventive Measures, and Organizational Governance from an Organizational Perspective.” In addition to those in charge of quality assurance and quality control as well as production, sales, and development departments also attended the seminar. We will continue our activities to improve the quality awareness of all Kuraray Group members.

Actions to Be Taken in Case of Quality Complaints and Product Accidents

Within the Kuraray Group, information on quality complaints received from customers is managed by its divisions, so responses to customers can be made promptly and action taken swiftly to prevent recurrence of the same flaws. However, Group-wide response schemes for material complaints and claims are prescribed by the Rules-on Product Liability (PL)-related Accident Response and Quality Complaint Report.

On the occurrence of a material product accident, the Corporate Sustainability Division will submit a situation report to the management and an administrative agency set forth by law, while establishing the Corporate Emergency Headquarters to take prompt and appropriate action from the customer’s point of view. Moreover, a mechanism to take corrective actions to clarify the cause and prevent recurrence has been established not only for a material product accident which requires an emergency arrangement but also general accidents.
 In 2022, we revised the “Kuraray Group PL-related incident response and quality complaint reporting rules” by reviewing the criteria for judging PL-related accidents and reporting claims in order to respond more appropriately to quality complaints and product accidents.
