Quality Assurance


│Social Background

In recent years, there has been growing public concern over product quality and safety. Casio remains keenly aware that it must do its very best for customers. Casio believes it can offer trust and peace of mind to customers by providing high-quality, exceptionally safe products and delivering premium-quality services to complement those products.

│Risks and Opportunities

Once an accident related to quality and safety occurs, it can pose a problem for the survival of the company, by damaging consumer trust in the brand. On the other hand, providing high-quality and safe products and services that provide peace of mind can lead to stronger corporate competitiveness.

Casio believes it is important not only to provide products and services that delight customers, but also to win acceptance from the whole of society and achieve sustainable prosperity based on mutual trust. Toward this end, Casio Quality includes everything from the quality of individual products, to environmental protection and recycling. Casio recognizes that the role of quality assurance is to deliver quality that satisfies customers in every possible way.


At Casio, the following basic approach and policies have been established to promote product quality, and they are used as indicators to gauge quality activities.

Quality Concept
Casio maintains a strong quality assurance system, based on its belief in "Quality First." This system requires all employees to make quality their first concern in every task they perform, enabling the company to offer products and services that please and impress customers. The company's commitment to quality supports its corporate growth and makes social contributions possible, while at the same time winning customers' trust and giving them peace of mind

Quality Management Policies
・To build a good corporate image, we offer products and services that please and impress our customers, gain their strong trust, and ensure their peace of mind.
・We respond to our customers' requests and inquiries with sincerity and speed, and reflect their valuable comments in our products and services.
・In all our business processes, we base our actions on the Principle of the Five "Gens"—in Japanese, genba (on site), genbutsu (actual goods), genjitsu (reality), genri (theory) and gensoku (rule)—and adhere to the basics of business operations.
・We capture and analyze quality assurance activities quantitatively, using reliable data, and use the analysis to make continuous improvements. We also maintain a quality information system that enables the sharing of quality information and prevention of problems before they occur, and prevents recurrence of quality problems.


In order to carefully maintain and improve Casio Quality, the company has created the quality assurance system shown in the diagram below. The Promotion Committee for Group-wide Quality Enhancement meets twice a year. It pursues activities such as making quality data accessible and easy to understand, and sharing quality information, while passing resolutions on quality policy and measures. The results are used for quality assurance activities in each division.

As the division in charge of group-wide quality management, the CS Headquarters is working hard to ensure quality, with the cooperation of all departments, while always pursuing the best solutions for customers.

The Casio Group shares the awareness that “Quality First” is the foundation of all operations, and the Promotion Committee for Group-Wide Quality Enhancement shares information on quality, product safety, and product regulations in order to raise the level of awareness across the entire group. An ISO9001 quality management system is employed at all manufacturing sites using the PDCA cycle, and “quality-first proposals” are made, incorporating improvements to processes and quality. All of this is part of Casio’s tireless effort to maximize quality.

Activity Results

(1) Plant Audits During the COVID-19 Pandemic

Casio carries out plant audit periodically to maintain quality and ensure safety. With the complications to in-person travel between countries since the COVID-19 pandemic began last year, we have begun performing remote plant audits. Since these audits began in fiscal 2021, we have verified that quality is maintained, identifying issues as necessary. Additionally, we plan to continue our use of remote audits along with in-person audits in the future, putting to good use the advantages offered by remote audits, including how they enable the participation of many involved personnel and allow video recordings to be preserved.

(2) Products in General: Improved Confirmation of Safety through Combustion Experiments, etc.

Casio maintains safety design standards, safe manufacturing standards, etc., to guarantee product safety, and we perform combustion experiments as part of this system. After verifying that no issues with design have been identified, we perform actual combustion experiments to verify the results in worst-case scenarios.

│Offering Users Peace of Mind

Casio believes that safety is the most important aspect of its products, as it ensures the protection of customers’ property and person. As shown in the diagram below, Casio performs safety audits* at every stage, starting with product planning, and refers to the Casio Product Safety Design Standards to ensure safety in the manufacturing process.

Accompanying the regular revision of the Casio Safety Design Standards, we regularly revise the Casio Safe Manufacturing Standards as well to guarantee safety.

* Safety audits: Design audits conducted based on the Casio Safe Design Standards

New products are divided into products with “new technology components” and products of the “usual rank.” Then, products that contain new technology components undergo an objective safe design review based on Casio’s own safe design standards. Usual rank products are checked for safe design by their respective business division, thereby ensuring that all products undergo a safe design review.

Product safety system

To comply with the legislative intent of Japan’s recently revised Consumer Product Safety Act, which went into force on May 14, 2007, the Casio board of directors has adopted the Fundamental Policies on Product Safety. Based on these policies, Casio has put in place the Product Safety Voluntary Action Plan which specifies the details of the steps to be taken.

Casio takes all possible measures to prevent product quality problems and product-related accidents. Still, the company is prepared for the unlikely event of a product-related accident. It has reengineered its response systems for handling these situations and established procedures for managing them. These include the steady, timely collection and dissemination of accident information, the issuance of notifications and reports to customers and relevant administrative agencies, prompt, appropriate response measures, efforts to identify causes, and measures to prevent any future recurrence.

In fiscal 2021, a notice for handling of an AC adapter was updated in “Important Notifications on Product Safety.” 

Education and Awareness Activities

It is very important that all employees have a strong awareness of quality so that Casio quality can be maintained. To this end, the first quality education program is given to all new employees.
1.Quality management education: Importance of maintenance management in manufacturing and practical explanations
2.Quality assurance education: Practical training from the quality assurance supervisors on improving quality
New employees experience quality management for themselves with on-the-job training in manufacturing at Yamagata Casio.
After they are assigned to their divisions, they participate in actual quality meetings and on-the-job training is given, covering issues in the market as well.
