In 1846 the entrepreneur Mansuke Nakarai founded his apothecary business for Japanese and Chinese medicines. In 1906 the company started business activities for Western pharmaceuticals and in 1908 began to import reagents from Germany. Right from the beginning the company has always been deeply involved with the progress in health and science, always adopting business to changing times.
