~Maintaining Excellence in SPF Animal Breeding – Inside CLEA Japan~

For more than half a century, CLEA Japan has been at the forefront of high-quality laboratory animal breeding in Japan.

Our mission: to deliver reliable, healthy animals that meet the most stringent global research standards.

Among the many disciplines in laboratory animal science, maintaining true SPF (Specific Pathogen Free) status is one of the most technically demanding.

It requires not only advanced facilities and protocols, but also the discipline, precision, and expertise built through decades of continuous refinement.

In this video series, we open the doors to our SPF operations — a process rarely seen outside our facilities — and show you the meticulous procedures our staff follow every day.

From entry protocols to cage changes and shipping preparations, each step reflects our unwavering commitment to animal health and research integrity.
