Risk Management for Stakeholders

We started the D-Quest Group (DQG) in April of the year 2000* as a new entity focused on managing risks for people and organizations to prepare for the upcoming twenty-first century. We did this because we believe that the thing companies in this new century need most is compliance management, supported in turn by sound and sustainable management. As a consulting firm specializing in human risk management, which is becoming increasingly important in an international society, DQG provides high-quality data, systems, training, and know-how that contribute to improving enterprise value.

Whistleblowing System
The DQ Helpline we offer is a third-party whistleblowing hotline system of the type recommended by the Consumer Affairs Agency of Japan. Early on, we built a whistleblowing service network that covers the entire planet, both within Japan and foreign countries. Over 1,600 companies have used this service to date.

DQG is extending the concept of “Risk Management for Stakeholders” to the rest of the world. This began with the founding of subsidiary DQ Europe in October 2018 in the German city of Frankfurt.

Strengths of DQG

History and
DQG's history has gone hand-in-hand with the advancement of fraud-risk prevention in Japan.
D-Quest, the core company of the group, got its start in the year 2000. Starting off with risk investigations related to people and organizations, we eventually developed and released our whistleblowing system in 2003.
Nowadays, third-party whistleblowing systems are widely known, but at the time it was a very novel concept.
In October 2004, we acquired exclusive licensing rights for Japan from the Association of Certified Fraud Examiners (ACFE), the world's largest organization for training experts in anti-fraud, and the following April we launched ACFE JAPAN. This was the start of Japan's first comprehensive program for anti-fraud training.
In light of the current globalization taking place in Japan and the need for corporate management as well as the sustainable operation exemplified by the Sustainable Development Goals and investments in environmental, social, and governance, we firmly believe that the organizational and human risk management provided by DQG plays a critical role in contributing to Japanese society. This history combined with our many accomplishments is the biggest advantage of DQG.

Another of DQG's strengths is the global network that we've been building since our founding, something which enabled us to constantly expand our business within an international framework.
For example, we began as a pioneer in terms of whistleblowing systems in Japan, but have grown so much as to be called a leader in global report hotline services. The primary asset that brought us this far is our globe-spanning network of law firms. The establishment of our subsidiary DQ Europe in October 2018 (Frankfurt, Germany) also bolsters this network.
By leveraging this global network for all DQG operations, we are able to provide high-quality services on a daily basis.

From the viewpoint of risk management, security is the lifeblood of a company. At DQG, we've implemented comprehensive security measures based on our information-security policy, focusing on the four areas of organization, personnel, technology, and physical access. We established a system for managing our information security and continually maintain and update that system. In addition, we've acquired the ISO27001 [ISMS] certification for information-security management systems related to corporate consulting.

DQG is also an industry leader in innovation. With our third-party whistleblowing system DQ Helpline, for instance, we developed and patented a framework that allows for two-way communication while maintaining the anonymity of reporters.
We are now establishing a division that develops services incorporating technology such as artificial intelligence and blockchain. We pursue innovation daily for the benefit of people and organizations.
