Message from the CEO


Overstep boundaries, bridge diverse factors and help society evolve “simply”

GRCS Inc. is a company that leverages technology to support the defensive aspects of corporate management covering the areas of governance, risks, compliance, and security. In recent years, companies are faced with issues that are becoming more complex as social conditions and the external environment are increasingly diversified. However, compared with Europe and the U.S., Japan is lagging behind in efforts to strengthen governance and take security measures.

In 2009, I came across the term GRC, which stands for Governance, Risks and Compliance, and felt that the concept of responding to the diversifying external environment and issues from each of these perspectives would greatly help companies resolve issues. This belief urged me to launch this business.

Subsequently, the Company added the perspective of security (S), which has relevance to GRC areas, to better facilitate the addressing of issues in Japan. Moreover, we worked to develop our own products to allow us to offer services with more flexibility, and endeavored to strengthen management and heighten operational efficiency by utilizing technology in these areas, where information management depends on personal skills and understanding, and where addressing issues tends to be slow. By doing so, we have supported prompt decision-making by corporate management.

Looking ahead, we will work to further deepen the GRCS businesses we have developed to date. At the same time, we intend to generate new and diverse GRCS concepts, such as Green, Reborn, Culture and Sustainable.

Since founding the Company, our aspirations have remained unchanged: To make the complex society simpler by joining hands with a variety of people and fully utilizing technology, as well as to eliminate all barriers and boundaries. To this end, GRCS Inc. will continue to evolve, not resting on our laurels but boldly taking on new challenges.
