Message from the President

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

Regardless of business area or type, the need to handle big data and utilize digital technologies have seen numerous companies shifting towards digitalization. This has been dubbed as an age of “Digital Transformation” (DX) across a wide range of industries.

In order for all companies, including us, to survive, Creating Shared Value (CSV) will be essential for addressing proactive collaborations and business partnerships across industries, asset sharing in non-competitive areas, as well as operation standardization.


Amid this trend, the role of CROs is becoming more significant than ever for the pharmaceutical industry to connect with clinical sites and continue drug development.
With the motto “All you need is CRO x IT”, CAC Croit aims to be an industrial role model by promoting efficiency in drug development while leveraging our IT strengths. We will continue to commit ourselves to supporting you as a valued partner. We will see things through your eyes to promote CSV and seek to foster coexistence and co-prosperity in the industry.


More than ever, our focus is on developing talent to increase your satisfaction with our service. As we strive to provide even more services to meet your needs, we have divided our business unit into East and West divisions to improve communication and pursue optimal processes.
We will continue to make steady efforts and move forward step by step to be “a company that will grow for the next 50 years” as an indispensable CRO to society.


We aspire to be a leading contributor to pharmaceutical companies forging the future of medicine and Japan by supporting every phase from drug discovery through to clinical development and postmarketing.


We look forward to further developing our working relationship with you.
