35093 Akicity           Discovered 1991 Mar. 14 by T. Seki at Geisei.
Aki city, in eastern Kochi prefecture, is on the coast of the Pacific Ocean and, blessed with warm winters, it prospers in agriculture. It is the birthplace of composer Ryutaro Hirota and Geisei Observatory founder Seizo Goto. Nora-Clock, the clock tower, is loved by the residents as the city's symbol.
