Discovered on 10 January 1999 by A. Asami at Hadano.
Shinseiko is the youngest natural lake in Japan and is located in Hadano, Kanagawa prefecture. As a result of the Great Kanto Earthquake of 1923, the river flowing through a valley was cut off and the lake was formed. Today the lake is famous as an area of great natural beauty.Naming citation (20031110/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
