Environmental Initiatives

Companion Animal Pharmaceutical Business
Because pets are family too
In the 21st century, animals have become more important for human welfare than ever before. Companion animals are full family members for many owners and research has begun to show that animals play crucial roles in our lives including with respect to animal-assisted activities, therapy and education.
In the area of companion animal pharmaceuticals, for the happy, healthy lives of animals, we provide not only high-quality drugs and dietetic foods, but also detailed support so as to contribute to the creation of an environment in which animals receive proper aging care and enjoy a good quality of life during each stage of their lives.


Production Animal Pharmaceutical Business
Ensuring food safety by improving production animals' health
Kyoritsu's Production Animal Pharmaceutical Business plays a vital role in ensuring food safety and reliability. The expertise and track record Kyoritsu has accumulated over more than half a century have established us an unchallenged position in the feed additives and reproductive fields. To support livestock businesses, we strive not only to provide high quality animal pharmaceuticals, but also to comprehensively reduce costs. As an early adopter and promoter of HACCP we deliver increased efficiency while constantly helping to prevent the global threat of infectious disease outbreaks by promoting immunization and the improvement of public hygiene.


Deodorizer Business
Preventing Environmental Pollution through Odor Solutions
As a comprehensive researcher, developer, and manufacturer of chemical reaction – based deodorizers and odor removers, Kyoritsu supplies more than 100 types of product tailored to diverse market needs.
