Risks and Opportunities for the Casio Group

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 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.

Management Approach


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.

In order to create a common group-wide awareness of "Quality First" being the foundation all operations, strong leadership is essential from top management and those responsible for quality. The Promotion Committee for Group-wide Quality Enhancement implements training to ensure employees understand and are widely aware of regulations and standards relating to quality and safety, and to learn technology expertise. This includes holding presentations for the improvement of quality management skills.

Casio's production plants carry out plan-do-check-act (PDCA) cycles using the ISO 9001 Quality Management System. In order to deliver reliability and peace of mind to customers that use Casio products, Casio employees focus on quality improvement.

Activity Results

Offering Users Peace of Mind

Casio makes every effort to ensure product safety so that customers can always use Casio products with peace of mind. As shown in the diagram below, Casio works to ensure product safety in each process from product planning, development, and design, to trial manufacture, evaluation, production, and delivery. In order to maintain and enhance these efforts, the company performs safety audits* and works to prevent potential problems from occurring, or issues from reoccurring.

  • * 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.
The company has also reengineered its response systems for handling those unusual situations when a product-related accident occurs, and has established procedures for managing such situations. 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 2019, a new notice was posted in “Important Notifications on Product Safety.” This was a precautionary statement on the safe and appropriate use of products, not a major case regarding product safety or quality defects.

Education and Awareness Activities

The first quality education 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.
