Japanese businessman and billionaire Keiichiro Takahara has an estimated net worth of $4.3 billion as of April 2016, according to Forbes. Currently based in Japan, Keiichiro Takahara is married with three children.

In addition to being the founder, Keiichiro Takahara currently serves as the chairman of Unicharm, a company that specializes on manufacturing sanitary napkins, diapers and other types of personal health care products.

Since 2001, his son Takahisa is serving as the company's chief executive officer. In 2012, the sale of adult diapers surprisingly surpassed the sale of baby diapers. This could be attributed to the fact that Japan is currently having an aging population. In the past year, company's stock price increased by around 25% due to the increasing sales in China and India. Unicharm is about to open its fifth manufacturing plant this year. The company also aims to expand its operations to other parts of Asia which include Vietnam, Thailand, Korea, Taiwan, and Indonesia.
