Eiken Chemical Co., Ltd. (Headquarters: Chiyoda-ku, Tokyo, hereinafter referred to as "the Company") has jointly produced and released today the educational booklet for elementary school students, "Unko Drill: Stool Test for Colorectal Cancer," in collaboration with Bunkyo-sha Co., Ltd. (Headquarters: Minato-ku, Tokyo, President: Shuji Yamamoto).

This booklet is an awareness content born from the desire to "make children laugh and learn, leading to actions that protect family lives," by combining the immensely popular "Unko Drill" learning materials, with over 10 million copies sold cumulatively in the series*, and our company, which has been involved in colorectal cancer screening for many years as a manufacturer of clinical diagnostic reagents.

It's precisely because it's "Unko Drill" that it gets through and is remembered.

In Japan, colorectal cancer is a major cancer in terms of both incidence and mortality, and early detection and early treatment are key to saving lives. However, screening participation rates remain insufficient.

This booklet, supervised by doctors, explains colorectal cancer screening with the humor and clarity unique to Unko Drill. It is expected not only to allow children to learn while having fun but also to naturally spark conversations at home such as, "Mom, Dad, have you had your test?"

Health Education Starting from Elementary School, "Thinking of Family"

In addition to distribution to schools nationwide that wish to receive it, the booklet is planned for use at colorectal cancer screening awareness events and other venues.

As a manufacturer of clinical diagnostic reagents, our company has supported "the front lines of testing" until now.
This initiative goes beyond that framework, representing our new endeavor to raise screening awareness throughout society and disseminate correct knowledge, starting with the next generation of children.

"Lives Can Be Saved Through Testing"—Take the First Step with Unko Drill

Through this booklet, we hope that as many people as possible will become interested in colorectal cancer screening and take actions that lead to saving lives. Moving forward, our company will continue to support people's health and peace of mind through testing, while also challenging new forms of communication that reach a wide range of generations.
