Message from the President

Constantly changing on the wave of the times and growing for the next 50 years

Artificial intelligence (AI) has already become something familiar to us as AI-equipped home appliances have drawn attention and automated driving tests have begun in the world today. Even in the pharmaceutical industry, the age of fully electronic medical records is just around the corner. The waves of changes are sweeping everywhere in the business world. We have to proactively change ourselves riding on the waves, rather than resisting them.

To capitalize the waves of major changes, we apply AI technologies and Robotic Process Automation (RPA) to the medical and pharmaceutical fields to reduce costs, improve quality, and strengthen information security. In addition, we will actively utilize the real world data to support innovation in the pharmaceutical industry in response to customers’ needs in the age to come of fully electronic medical records.

From time to time we are forced to make large-scale changes, but on the other hand, I believe that it is very important to accumulate small-scale changes in daily life.

The important accumulation of such small-scale changes is the development of human resources. “Personnel” who carry out our services need to grow in order to increase customer satisfaction to our services. We will grow together and provide better services in company-wide efforts.

We aim to be a company that will grow for the next 50 years. To be such a company, we must become a more indispensable CRO to society than ever. We will continue to make steady efforts and move forward step by step to achieve our goal.

We look forward to even better relations with you.
