T akahisa Takahara is a Japanese billionaire and the chief executive officer of Unicharm, a major manufacturer of disposable hygiene products. He is the son of the company's late founder, Keiichiro Takahara, who established the business in 1961. Unicharm has grown into a global leader in the production of personal care items, with a dominant market position in Asia for many of its products. The company's well-known brands include MamyPoko and Moony diapers, Sofy and Charm feminine hygiene products, and a range of pet care items.

Takahisa joined the family business after a stint in banking and took over as CEO from his father in 2001. As the second-generation leader, he has been the architect of Unicharm's aggressive and highly successful international expansion strategy, particularly in emerging markets across Southeast Asia and India. This global growth has been the primary driver of the company's increased value and the Takahara family's immense fortune, which is derived from their large controlling stake in the publicly traded company.
