The name "Shiseido" comes from Chinese Yi Jing, the Book of Changes from the Four Books and Five Classics of Confucianism. While our products have their origins in cutting-edge western pharmaceuticals, the company takes its name from eastern philosophy. This forward-thinking blend of Western science and Eastern wisdom has always been the cornerstone of Shiseido.
