[What is the Privacy Mark System?]
The Privacy Mark System is a system that evaluates businesses that have established a system for taking appropriate protective measures for personal information in compliance with the Japanese Industrial Standard "JIS Q 15001 Personal Information Protection Management System - Requirements," awards them a Privacy Mark to indicate this, and allows them to use the Privacy Mark in their business activities.
For businesses, the Privacy Mark can be used as an effective tool to demonstrate not only compliance with the law, but also that they have voluntarily established and are operating a personal information protection management system with a higher level of protection.

[What is the Health and Productivity Management Excellent Corporation Certification System?]
This system recognizes large companies and small and medium-sized enterprises that are practicing particularly excellent health and productivity management based on initiatives that address local health issues and health promotion initiatives promoted by the Japan Health Conference. By making excellent corporations that are working on health and productivity management visible, the goal is to create an environment in which they can be socially recognized by employees, job seekers, related companies, financial institutions, etc. as "corporations that consider employee health management from a management perspective and are working on it strategically." This system certifies "Health and Productivity Management Excellent Corporations" in two categories: the "Large Corporation Category" for large corporations, etc., and the "Small and Medium-sized Corporation Category" for small and medium-sized corporations, etc. If a company is certified as a "Health and Productivity Management Excellent Corporation," it will receive social recognition from employees, job seekers, related companies, financial institutions, etc. as "corporations that consider employee health management from a management perspective and are working on it strategically."
