Oriental Yeast was founded in 1929 as Japan’s first manufacturer of baker’s yeast in order to carry out our mission to ensure a dependable supply of good-quality domestically produced yeast to Japan’s bread industry. Under our corporate philosophy of “Contributing to human health through our business activities by conducting business with an entrepreneurial spirit” we have since remained committed to developing new technologies based on the effective use of yeast and striving to advance into new business areas.

In our food business, under the spirit of “Thinking in terms of bread”, we develop sweet and cooking fillings and bread improvers in addition to Bakers’ yeast, which are deployed not only to the bakery and confectionary industries but also to a wide range of food markets. In our business expansion overseas, we have constructed our first overseas production base in India, which supplies yeast to the Indian market. In addition, taking advantage of the popularity of ramen ( noodles ) which is expanding worldwide, we are exporting kansui powder as a leading manufacturer in Japan, in an effort to further increase the popularity of “Japanese ramen.”

In our bioindustry business, we are focused on the development and production of raw materials for diagnostic reagents such as yeast extracts and coenzymes, which contribute to the development of diagnostic reagents, while also working to expanding into overseas markets, including the U.S.A., the Netherlands, and India. We also support basic medical research and drug discovery research through the supply of safe and reliable laboratory animal diets developed using yeast and its culture residues and related services, contributing to new discoveries in the field of basic medicine and the birth of new drugs.

On April 1, 2026, we took over Nisshin Pharma’s health food business as part of the restructuring of the business portfolio of the Nisshin Seifun Group, making way for a new business framework. By enhancing the synergy with existing businesses, we aim to improve our competitiveness by specializing in the nutraceutical field in the dietary supplement market.

As a technologically driven company, we will remain committed to our spirit of taking on new challenges as we work to become an indispensable part of our customers’ business.
