Japan Quality Assurance Organization
We provide technical support service available by toll-free phone and contact form on the website and our dedicated support staff members do their best to respond to inquiries from our customers quickly and accurately.
We also provide a wide range of services such as visiting to customers and product evaluation at our facilities with customers present, as well as technical consultation.
We have stored the details of more than 100,000 technical consultations we received in a database to utilize such data to improve products and services.
We also strive to improve them by collecting complaint information, performing customer satisfaction surveys, and continuously examining and analyzing customer feedback.
Response to complaints from the field
When failures occur, our technical staff members deal with them promptly and accurately. We provide maintenance services such as failure analysis, repair, and overhaul when defects or failures occur in the field or within processes.
In case of defects, we always ask customers about the situation and environment where defective products are used and accumulate such information. By using accumulated data of past instances, we work hard to investigate the cause and fix defects as soon as possible.
In addition, we analyze the defects of products returned from the market and provide feedback to the product development site and the production site. Then we implement the PDCA cycle for improvement from a customer perspective. By doing so, we strive to improve product quality and strengthen our services so that they can satisfy customers.
Protection of customer information
Cosel’s Standards for Voluntary Actions specify that “we will never leak confidential information without a appropriate reason.” We properly handle the information we receive from our customers and never leak those pieces of information
There are concerns that mineral resources mined in the Democratic Republic of the Congo and 9 neighboring countries are financing armed groups in these regions. In order to address this issue, the Dodd-Frank Act was enacted in July 2010 in the United States and U.S.-listed companies are required to conduct inquiries to determine the refiners of the conflict minerals they use and file a report to the U.S. Securities and Exchange Commission.
We have agreed with the purpose of the Dodd-Frank Act and established the rules for conflict minerals investigation to promote the responsible procurement of minerals. We explain the purpose and necessity of the conflict minerals investigation to our clients and collect information utilizing a CMRT (Conflict Mineral Reporting Template).
When requested to disclose information on the results of the conflict minerals investigation by customers, we provide information with a CMRT.
