Privacy Policy

Since its establishment in 1959, Marketing Center has been contributing to society primarily by providing statistical information about consumers’ realities and opinions through market research and public opinion surveys to companies, organizations, etc.

In the handling of personal information of the individuals surveyed, Marketing Center adheres to the international code of conduct for the marketing research industry, the “ICC/ESOMAR International Code,” as well as the “Marketing Research Code” and “Marketing Research Industry Personal Information Protection Guidelines” established by the Japan Marketing Research Association.

We have established the following policy regarding the protection of personal information, and we declare internally and externally that we will implement this policy to establish a more appropriate and secure personal information protection system, aiming for thorough privacy protection.

1. Rules for the Collection (Acquisition), Use, and Provision of Personal Information

In the process of collecting (acquiring) personal information, our company consistently defines the purpose of use, employing fair and proper means. The utilization of personal information strictly adheres to the scope of the agreed-upon purpose, limited to cases where the individual has provided consent. In instances where usage extends beyond the initially specified purpose, explicit consent from the individual is obtained beforehand. While our general practice is to refrain from providing personal information to third parties, if such provision is necessary, consent from the individual is obtained in advance. Based on these principles, our company manages personal information within the scope of the purpose of use, ensuring accuracy and up-to-date information.

2. Security Management of Personal Information

To prevent leakage, loss, or damage of personal information, our company implements appropriate security measures, including measures against unauthorized access and computer viruses. We establish organizational, personnel, physical, and technological security management environments.

3. Compliance with Laws and Other Standards Regarding Personal Information

In carrying out business activities related to handling personal information, our company’s executives and all employees comply with relevant laws, guidelines established by the government, and guidelines set by the Japan Marketing Research Association, an organization to which our company is affiliated. This includes adherence to the “Marketing Research Code” and the “Marketing Research Industry Personal Information Protection Guidelines.” We act in accordance with internal regulations.

4. Handling of Inquiries, Complaints, and Consultations

For inquiries and complaints regarding our company’s handling of personal information, please contact the phone number provided in “5. Contact and Complaint Reception” under “Handling of Personal Information.” We promptly respond to requests from the subject of disclosed personal information or their representatives, including notifications of the purpose of use, disclosure, correction (correction, addition, or deletion of content), and suspension of use (cessation, deletion, and suspension of provision to third parties).

5. Continuous Improvement of the Personal Information Management System

To put our privacy policy into practice, we have established and operate a personal information management system, including regulations. To enhance effectiveness, we conduct education for all employees, audits of operational conditions, and other activities at least once a year. By continuously reviewing and improving the personal information management system, we ensure that all employees are thoroughly aware of and comply with the latest compliance requirements.
