35076 Yataro           Discovered 1990 Jan. 21 by T. Seki at Geisei.
Yataro Iwasaki (1835-1885), born in Inokuchi (present-day Aki city, Kochi prefecture) was a close friend of Ryoma Sakamoto and played a crucial role in bringing about the Meiji Restoration. He also made a great contribution to the economic development of Japan.
