Nakatani Family

Background

The Nakatani family wealth originates from Taro Nakatani, who founded Sysmex (originally as a subsidiary of Toa Electric) in 1968. Taro Nakatani was a visionary who recognized the potential of automated blood analysis technology. After visiting the United States in 1960, he pioneered the development of hematology analyzers in Japan. Taro Nakatani passed away in 1984, and his widow Tadako Nakatani became a major shareholder. The family maintains significant holdings in Sysmex Corporation, which has grown into a global leader in medical testing equipment with operations in over 190 countries. Tadako Nakatani was among Japan's wealthiest women before her passing.
