Japan Leather Mfg. Co., Ltd. was established in 1907 and officially renamed Nippi Incorporated in 1974. In the more than 100 years of development, we have continuously used cutting-edge science and technology to change the skin of natural organisms and animals, making them various materials for people's daily lives. After years of hard work, we have the proprietary technology for leather tanning and dyeing, and are able to manufacture high-quality leather materials for leather shoes, bags, leather jackets and other products. Therefore, we already occupy a position in the industry that other competitors cannot match.

The company has also developed new uses for natural organisms. For example: By refining and decomposing its main ingredient, collagen, we produce high-quality gelatin products. In addition, we also extracted low molecular weight collagen peptides. These materials are effectively used in various fields such as photography, food, and medicine. In addition, collagen is refined by special treatment methods, molded or dissolved, and processed into raw materials for sausage casings and cosmetics.

At present, as the main component of collagen, extracellular matrix has become the focus of research in molecular biology and cell biology, and has attracted attention from various fields. The important role of this ingredient in organic matter is being continuously clarified. At Nippi, we study this ingredient from a bioassay perspective and carry out research and development work on the in-depth use of this ingredient in the field of medical materials.

As a supplier of high-quality and high-performance biomatrix products (Nippi calls it "Biomatrix" products), Nippi will focus on technological development; at the same time, as the main force of Biomatrix Engineering in Japan, We hope to continue to contribute more to the improvement of people's daily living standards.
