Responsibility to customers

Basic Policy

The Mitsubishi Electric Group is committed to improving its technologies and services by applying creativity to all aspects of its business, to thereby enhance the quality of life in our society, as stated in our corporate mission. This commitment inherits the principles outlined in the Keys to Management (in Japanese, Keiei no Yotei) with regard to "our contribution to social prosperity," "quality improvement," and "customer satisfaction," and forms the basic spirit of our relationship with society and our customers.

To give concrete shape to this basic spirit, the Seven Guiding Principles define our actions in response to society and customers. It teaches us to establish relationships based on trust, provide the best products and services with unsurpassed quality, and respond to customer expectations through technology by promoting research and development and pioneering new markets.

Under these principles, we constantly strive to increase customer satisfaction and contribute to social prosperity in all aspects of our business, from the production of high-quality, easy-to-use products to our after-purchase support and response to major issues.

Four Basic Quality Assurance Principles

The Four Basic Quality Assurance Principles reflect the spirit of "Service through Quality" adopted in 1952 and "Memorandum of Quality" issued in 1958. The spirit of serving society through steady quality continues to be upheld by each employee of the Mitsubishi Electric Group up to the present day.

Four Basic Quality Assurance Principles

  1. Product quality is our top priority. It comes before price and on-time delivery.
  2. Our commitment to the highest quality under any circumstances is unwavering.
  3. Products must be safe to use, have a long usage life, and have consistent performance.
  4. Every manager and employee involved in manufacturing a product shares equal responsibility for product quality.

Based on the Corporate Statement and the Seven Guiding Principles, the Mitsubishi Electric Group promotes initiatives to ensure product safety under the following principles:

Product Safety-related Principles

  1. We will not only comply with the laws related to product safety, but also work on offering safe and reliable products to our customers.
  2. We will prevent product-related accidents by indicating cautions and warnings to help customers use our products safely.
  3. We will work actively to collect information about product-related problems, disclose them appropriately to our customers, and report them quickly to the government and other bodies as required under the law.
  4. If any serious accidents occur resulting from product-related problems, we will take appropriate measures to avoid further damage.
  5. We will investigate the cause of product-related accidents and work to prevent any recurrence.
  6. We will make continuous efforts to improve our product safety promotion system.

Particularly in regard to consumer products, Mitsubishi Electric is committed to preventing serious hazards that could result in death, injury, fire, or other damage, by subjecting all products to a quantitative risk assessment at the development stage, while also designing and developing products in consideration of their end-of-life management (to ensure safety even at the stage where products are prone to break or be discarded). At the same time, our Customer Service Center in Japan operates 24 hours a day, 365 days a year, to assist customers and gather their views about Mitsubishi Electric products. Furthermore, we disclose accident information, including information on the status of ongoing investigations, on our Japanese official website.
