With the theme of merging nature with chemistry,

we aim to establish an industry situated between the levels of manufacturing

and commerce based on the concept of living together with nature.


Since before civilization existed, mankind has had the power to heal naturally and has understood the inherent power of herbal medicines. As our society advances however, our basic knowledge of nature remains unchanged. We at Oryza will contribute to peoples’ health and wholesome lifestyles by gradually revealing this undiscovered fortune. Since humans are a part of nature’s cycle, we believe in her power. We should take advantage of this insight when using our technological knowledge to discover her hidden treasures. This concept of merging nature and chemistry does not belong in any one industrial category, but is situated between manufacturing and commerce. By founding our company on the idea of placing importance on nature and by undertaking innovative research into new concepts, Oryza aims to become a human health company known around the world.
