Our Group's basic philosophy regarding quality is to “Prioritize quality in
our products and earn the trust of customers.” This philosophy is embodied by
and integrated on an organizational level through the Group Code of Conduct
and the Code of Ethical Conduct, among others.
In line with our management philosophy, each internal company
has formulated its own quality policy and is working actively to acquire
and update certifications, including ISO 9001 or JIS Q 9100, and making
continuous improvements of quality management systems.

We have established a Quality Management Supervisory Office to deal with
company-wide issues relating to quality under our Headquarters’
administrative divisions.
The Quality Management Supervisory Office
engages in the cross-organizational management and supervision of quality
to ensure that our Group's products remain above a certain level of
quality. The office also engages in activities to prevent risks to quality
before they manifest. More specifically, in addition to maintaining and
managing the Technical Production Regulations, which are company-wide
rules regarding the quality of our products, the Quality Management
Supervisory Office complements the independent quality management efforts
of individual quality assurance departments by conducting inspection
quality audits of each internal company and subsidiary.
Within each internal company, the Quality Assurance Department is established
independently from the Sales, Engineering, and Production departments,
providing direction and guidance in the contracting, design and development, purchasing, production, inspection, and service stages of the
work process. In addition, we have established a framework of internal
company rules, allowing each internal company, with their varying
characteristics, to draw up its own operational rules as long as they do
not violate the Technical Production Rules.
The Quality Subcommittee was established as a forum for sharing information and resolving cross-organizational quality
issues within the Company. It meets under the jurisdiction of the Chief Quality Officer, with the quality managers of each
internal company and subsidiary as members. It is held four times a year by the Quality Management Supervisory
Office to identify Company-wide problems and future challenges relating to quality, and to formulate measures to
resolve them. In the event that concerns emerge regarding quality at an internal company or subsidiary, a report is
made to the Chief of Quality at a Quality Subcommittee meeting. If the Chief of Quality deems it necessary, the
Chief provides instructions to correct the issue and conveys information about the issue to the senior management at the Management Conference, etc.
The Quality Management Supervisory Office conducts inspection quality audits for each internal company and subsidiary, ensuring audit effectiveness while continuously making improvements to enhance the product inspection systems (inspection quality) of each company and subsidiary. We also review the audit methods and scope each fiscal year and actively work to make improvements so that the audits do not become a mere formality.
At the Quality Subcommittee, in order to further improve product quality, we utilize the results of the inspection quality audits conducted by the Quality Management Supervisory Office and share insights and lessons learned that will contribute to quality improvements. In this way, we are promoting initiatives such as preventing potential risks ranging from minor deficiencies to serious issues as well as implementing early warning management.
Internal quality audits are one means we use to maintain and strengthen
quality management systems (QMS*1), and we conduct internal auditor education in
order to maintain and enhance the capabilities of our lead and regular
auditors. Further, each of our internal companies holds meetings regarding
quality (QC*2 meetings, quality committees, etc.) to report defects
and share solutions.
We provide hierarchy-based training on quality assurance and QMS for employees upon joining the company and when they are promoted. As part of our ongoing awareness-raising efforts, we conduct regular sessions on human error and implement continuous measures to prevent defects. Each November, we designate a "Quality Enhancement Month" and display outstanding quality slogans submitted by employees at our plants. We also conduct circle activities (KAIZEN/improvement activities) in each workplace that focus on the theme of "improving QCD*3" to maintain and strengthen awareness of quality.
We encourage employees to acquire QC certification as part of their self-development. Instructors provide supplementary training to those who wish to pursue the certification, resulting in a large number of qualified employees.
We have extended our quality control activities to TOKYO KEIKI PRECISION TECHNOLOGY CO., LTD. (Vietnam), part of the Hydraulics and Pneumatics business segment, and are working to enhance quality management by sharing information through quality meetings and related initiatives.
For specially controlled products, inspection details are individually agreed upon with the customer. We have therefore established a separate QMS for these products. Our inspection quality system is further strengthened by providing professional ethics education, training and appointing inspectors, registering them, and conducting unannounced audits of the relevant divisions. In fiscal 2024, we held basic training courses on hydraulics related to quality, tailored to participants’ skill levels. These courses were organized separately for new employees, employees in their second or third year, and mid-career hires, in an effort to raise overall competence and reduce complaints from the field.
The Electronic Equipment Department of the Fluid Power & Control Systems Company has started holding QC meetings with two key suppliers, setting shared KPIs and carrying out related activities to foster quality awareness across the supply chain.
Training sessions conducted by personnel in charge of quality were held at company meetings attended by all managers, with the aim of enhancing quality awareness as a shared understanding in all departments.
In order for our employees to learn quality control
methods and improve their awareness of quality, we
encourage them to acquire QC certifications and hold
training sessions for the exam. These activities have produced a large number of certified persons.
Participation in training sessions for obtaining QC certifications covers the Marine Systems Company, the
Electronic Equipment Department of the Fluid Power & Control Systems Company, the Production Department
of the Inspection Systems Company, and TOKYO KEIKI TECHNOPORT INC., with the entire Yaita Plant continuing to promote awareness activities and working to ensure shared quality awareness and prevent fading interest.
