We were established in 1959 aiming to produce fertilisers and livestock feeds by cooking juice of fish. Shortly after, we diverted our business to production of extract seasonings, then widened the field to production of natural seasonings and dried food materials.

In the 1980s, we started developing functional materials. Since then, we have achieved great successes such as establishment of industrial production method of N-Acetyl glucosamine (NAG).
Not only NAG but also we have developed various functional materials such as Anserine, Collagen peptide and Fucoidan using our core technology “extraction”.

Pursuing “Tastiness and heath”, now we are mainly manufacturing and selling seasonings and functional materials derived from natural sources.
Not only for food, our products are widely used in the health and beauty industry and adopted in a large number of finished products in and out of Japan.


In 2002, we completed the acquisition of the international quality management system “ISO9001” for the whole company. However, we will never stop improving our quality for customer satisfaction.
