Dec. . 2009 Kihara Memorial Yokohama Foundation for the Advancement of Life Sciences started to build a new GMPfacility "Yokohama Biopharmaceutical Research and Development Center (YBIRD)" for the technological research on and production of recombinant proteines for clinical trials, and called for its operating company . With competitive application, YBRS was appointed as the managing- operating company.
April . 2011 In March 2011,the construction for the GMP facility, Yokohama Biophamaceutical Research and Development Center (YBIRD) was completed, and from April 2011, YBRS started to operate it. (For details of YBIRD, readers are requesuted to consult the home page of KIhara Memorial yokohama Foundation for the Advancement of Life Sciences(www.kihara.or.jp)
Capital: 86,250,000Yen as of Dec. 31, 2010


1. Contract production of recombinant proteins from already established recombinant micro-organisms or cultured mammalian cells. While our most familiar organisms are recombinant E.coli and CHO cells, other organisms will be considered.
2. Contract production of recombinant proteins from already cloned genes and plasmids, and yet recombinant production systems to be established. A recombinant system using E.coli suitable for industrial production is in our hand and available.
3. Contract researches and consultation to solve specific problems in the industrial production of candidate biopharmaceuticals.
4. Contract researches for technological R&D including those lead by the goverment.
Representative Business Model


1. For the technological development, small scale production, and purification of recombinant proteins for research uses 5 to 90 liter jar fermentors in a P2 or a LS2 laboratory.
2. For the preparation of microbial seed stocks and master cell banks using a GMP controlled P2 laboratory.
3. For the production and purification of recombinant proteins suitable for safety studies and clinical studies. Lines of culture vessels and purification instruments are installed in tow separate sets of GMP controlled P2 and LS1 laboratories, one with upto a 300 liter jar fermentorfor microbial use, and the other with upto 500 liter single use culture vessels for mammalian cell cultures- resepectively.
*Facilities are located either in YBIRD or partner's companies, both of which are operated or managed by YBRS.

1. GMP controlling technologies and experiences with international standard for the production of active ingredient for investigational new drugs.
2. Molecular biological technologies including cloning genes in plasmid, formation of recombinant organisms, and facilities to pursue them.
3. Technologies of cultivation and downstream processing for high quality recombinant proteins and facilities to pursue them.

Yasuaki KASE, Licenced pharmacist, President
After being educated in pharmacology, and having developed his career as a medical researcher and business manager for almost twenty years in Shionogi Pharmaceutical Co., he was invited to drive R&D projects in Nichi-Iko (pharmaceutical company), and then to steer a whole pharmaceutical company in Roman Insdutry Co. Ltd. With his rich exeprience and human relationship, he founded YBRS in 2006 and have been steering it since then.
Toshiharu MATSUMURA, Ph.D. Executive Director & CRO
With his backgound in biochemistry, and having enjoyed academic career for twenty years in Univ., Univ. of Tokyo, Stanford Univ. and others, he joined in Meiji Milk Products Co. Ltd. There he lead a new biopharmaceutical project from its molecular genetic stage to successful GMP production. Then, he was invited to Roman Industry Co. Ltd, for the production technologies of candidate biopharmaceuticals. In 2007, he joined in YBRS as an adjunct member, and since 2010 he hasbeen leading scientific part of YBRS.
Yutaka KOHNO, Ph.D. Executive Director
With his degree in medical science, he developed his career as a research scientist in Fujisawa Pharmaceutical Co., and in NIDDK, NIH. After twenty four years of this scientific carreer, he was then invited to join in the venture capital specialized in life science, Bio-Frontier Pertners Inc., where he has been engaged in incubating bio-venture companies with seeds for new drugs. Currently he is extending his expertise and capabilty in new business field in bio-industries. In YRBS, he takes crucial role in co-ordinating R&D plans with business partners.
Mitsuo FUJINAMI, MA, Auditor
Being educated in Keio University Graduate School of Economy, and after having spent his first bussiness career in his family business, he joined in Japan Associated Finance Corporation, which was the first venture capital established in Japan. His capability in accounting business flourished since then, leading him to found a financing company by himself. His contribution in YBRS is not only as an auditor, but is highly appreciated as a financial adviser.
Shoju KAMEYAMA,PhD. Maneaging Director of Production Tecnology Division
With his background in biological science and technology, he initiated his carreer in Midori Juji (Green Cross), Co. Ltd, where he joined in several biopharmaceutical development project including the recombinant production of human serum albumin. Through the process of company reformation towards Mitsubishi Welpharma, he continued to be in the positon of developing biopharmaceutical technologies towards the successful completion of HSA project there. In 2006, he spinned out and joined in Oxygenics Inc. for the development of artificial red cells, from where, YBRS succeeded in scouting this expert technologist as a core member.
