The history of Shukokai Incorporated is the history of the research and development of cancer vaccines. It has concentrated its efforts on the clinical application of cancer vaccines for more than fifty years when no one else showed an interest in cancer vaccination. In more recent years, international research studies have discovered scientific evidence that the body's immune mechanisms can recognize and eliminate cancer, which has led to a global awareness of the potential for cancer vaccination.

Shukakai Incorporated, a leading pioneer in cancer research, recognized that while it is important to create a cancer vaccine to prevent cancer, treating cancer is even more urgent. So, in 1990, Shukokai Incorporated opened Hijirigaoka Hospital in Tama City, Tokyo, to manage the whole process of cancer treatment from early care to relief care. Then, in 1999, it participated in the promotion of local elderly welfare by opening Hijiri-no-Sato Elderly Health Care Facility adjacent to Hijirigaoka Hospital.

At Shukokai Incorporated we consider cancer to be a phenomenon of aging and advocate that our patients understand their illness and participate more personally in their treatment. In cooperation with the Immunotherapy Conference, a Non Profit Organization (NPO) started in 2001, we are working hard to help our patients live out their lives happily by reducing the negative affects that come with the worry and anxiety of cancer diagnosis.
