Quality Assurance
Basic Attitude Towards Quality Assurance
JUKI has been committed to providing unbreakable JUKI quality since its founding.For industrial products in particular, we continue to maintain and improve JUKI quality. Our mission on the manufacturing front is to “keep customer factories running” by giving top priority to product reliability and stable operation. Thanks to its quality efforts, JUKI was recognized for its excellent quality control practices in the industrial sewing machine sector and received the prestigious Deming Prize for Implementation in 1981. These commendations attest to JUKI's sincere attitude toward quality and continuous efforts toward improvement.Now society's view of quality has become even more stringent.We will continue to clearly stress the high-quality standards of products and services as a distinct strength and will ensure that customers experience this quality for themselves.
Five-Article Quality Declaration
The “Five-Article Quality Declaration,” a set of action standards for the “Quality,” are well-entrenched in every division of the JUKI Group. JUKI continues to do all that it can to nurture a mindset focused on providing quality to customers.
- 1 We will comply with laws, rules, and promises made to our customers when providing products and services.
- 2 We will place the highest priority on the safety and security of our customers in our products and services.
- 3 We will always sincerely listen to our customers’ opinions and strive for continuous quality improvement.
- 4 We will gain the trust of our customers and grow our business by enhancing quality based on the 5-gen principle.
- 5 We will contribute to the sustainable development of society by improving the quality of our products and services.
Quality Management System
JUKI maintains and improves quality by holding regular quality-focused meetings of the development, manufacturing, and sales departments of each business, and by including suppliers in their quality-focused dialogs. In the unlikely event of a quality problem, the JUKI Group deploys a Group-wide system designed to solve defects as quickly as possible.

Quality Assurance Initiatives
The “Four-process Consistency Activity,” a project we have been working on since 2019, has achieved tangible results, but progress has been slowed by quality issues on the manufacturing lines. In this connection, we launched the following measures in FY2024 as another of our "Quality Re-Inspection Activities" to further improve manufacturing quality.
Quality Re-Inspection Activities
| Business partner audits | We conduct audits of our business partners and determine the frequency of inspections and guidance from JUKI based on their technical and management capabilities. We eliminate the delivery of defective (non-conforming) products and stabilize quality by deploying a product-acceptance system tailored to the technical capabilities of our business partners. (JUKI audited 298 companies in 2024.) |
|---|---|
| Cross-audits between manufacturing sites |
The four-process consistency activity revealed that the self-audit tended to be subjective and to accommodate site-specific circumstances in ways that inadvertently hampered improvement levels. Therefore, we improved our auditing methods to enable third-party process audits (two-process consistency confirmation) by conducting cross-audits in which individual manufacturing sites audited each other. By sharing strengths and visualizing weaknesses between bases and implementing improvement measures, we will improve process quality to ensure that defective products are never produced or overlooked. |
| Manufacturing proposal document |
Since products with new features tend to have more problems, we added a step to submit a manufacturing proposal as a manufacturing-based risk assessment covering things like past manufacturing issues, ease of manufacturing, standardization and reduction of parts, and work safety during the product development process. These manufacturing proposals stabilize mass production, improve product quality at launch, and make new features easier to understand. |
Maintenance and Management of Quality Management Systems
JUKI has obtained ISO 9001 certification at each of its production sites and continuously maintains and improve its quality management system. The OHTAWARA PLANT, JUKI’s main domestic factory, formulates annual plans for quality activities and responds to ISO audits and QC activities. JUKI’s Quality HKK Committee launched at the OHTAWARA PLANT in FY2024 identifies quality risks in manufacturing sites, compiles countermeasures and evaluations, and deploys a system for thoroughly improving risks. Quality management is implemented at other JUKI’s production sites through internal audits and external evaluations performed in accordance with ISO standards.
