About Nomura Siam International

About Us

Nomura Siam International Co, Ltd., based in Bangkok, Thailand, was jointly established in 2012 by CLEA Japan, Inc.,

and Nomura Jimusho, Inc., to provide one-stop service for the laboratory animal field.


We are the exclusive distributor of M-CLEA Bioresource Co., Ltd., a joint venture company of CLEA Japan, Inc.,

Mahidol University, and Nomura Jimusho, Inc., which breeds high-quality laboratory mice and rats in the Samut Prakan

Province of Thailand.  M-CLEA Bioresource Co., Ltd., is granted licenses to produce “Jcl-brand” animals by CLEA Japan, Inc.,

and conforms to the breeding system having been consolidated by the licensor to maintain the “Jcl-quality,” which is ensured

by means of periodical microbiological and genetic monitoring by the ICLAS Monitoring Center in the Central Institute for

Experimental Animals in Japan; M-CLEA Bioresource Co., Ltd. is the first breeder in Thailand supplying world-standard

SPF animals, including unique disease models.


As a one-stop service supplier, we not only sell laboratory animals but also handle a wide range of related products, including

equipment for rearing animals and experiments, feeds, and bedding, as well as provide consulting services for pre-clinical

research and designing facilities for laboratory animals.


In addition to our business activities, we are determined to contribute to enhancing interest in animal welfare and improving

the use of laboratory animals in Asian countries, which we hope will ultimately lead to improvement of the quality, health,

and well-being of people’s lives.
