Corporate philosophy

The aging society is energized through drug development support and care


Our company name “Pacific Grove Co., Ltd.” means a peaceful grove. It is a place to relax, where people meet and heal each other. To provide new drugs to people as quickly as possible, we have been working in the clinical study subject recruitment business since 2004, with our Medical volunteers Group, JCVN.


According to a national government release, there are 34,590,000 elderly people, aged 65 or over in Japan, and the rate of aging is 27.3%. Thus, more than one in four Japanese people are elderly (Cabinet Office data, 1st October 2016).


We focus on recruiting people over 65 years of age for clinical trials, and have enrolled more than 2,000 people for phase I trials.


We provide a reliable support system with two-way, open communication channels so that elderly volunteers can participate in clinical trials with ease. We also acquire health data of elderly volunteers through numerous health measurement opportunities and medical checkups.


Health information is entered into our database which is used to select the most appropriate volunteer candidates for each clinical study. Because of our efforts, we have achieved a high number of elderly participants enrolled in clinical trials.


Through managing and administering nursing homes for the elderly, health data is captured in a diverse way and utilized in subject recruitment.


Medical treatments aim for the eradication of diseases and that is why Pacific Grove Co., Ltd. aims to connect the most appropriate volunteers for all kinds of clinical studies.


If a goal is simple, the ways to achieve it are limitless. Ours is an endless goal.

Pacific Grove Co., Ltd. is the only company that provides services, drug development support, and nursing care. We aim to play a key role in the local community and Japan’s medical treatment and health industry.
