Group Companies & Representative Office

At Oriental Yeast we refer to group companies as "affiliated companies," and we were early to realign the group and make our locations more efficient in order to enhance the added value and improve our performance as a single corporate entity.
We currently have 11 affiliate companies inside and outside of Japan working as a group with unified business objectives and purpose.

Overseas we have two locally incorporated units, OYC Americas, Inc. (USA) and OYC EU B.V. (Netherlands), as well as joint ventures with the Nisshin Seifun Group in India and China, Oriental Yeast India Pvt. Ltd. and Nisshin Seifun OYC (Shanghai) Co., Ltd., respectively. We have also established an office in Singapore for the purpose of conducting market research in Southeast Asia. Our business development on a global scale has also revolved around numerous foreign companies with whom we have established contractual or business relationships. We also use the worldwide information obtained through this network as feedback for our operations within Japan, helping us to enhance our products and improve our services for the Japanese market.
We are currently strengthening our efforts in the BRIC nations (Brazil, Russia, India, and China), Southeast Asia, and South America with the aim of expanding our business in those regions.
