Unicharm traces its corporate roots back to Taisei Kako Co., Ltd., which was founded by Keiichiro Takahara. Takahara's family had previously operated a traditional paper manufacturing business in the Shikoku region of Japan. After resigning from his father's paper manufacturing enterprise in February 1961, Keiichiro Takahara officially established Unicharm, embarking on a path that would grow the localized startup into a major global multinational corporation specializing in disposable hygiene and consumer wellness products.
