8493 Yachibozu           Discovered 1990 Jan. 30 by M. Matsuyama and K. Watanabe at Kushiro.
Yachibozu, or tussocks, are often seen in the Kushiro Marsh on the island of Hokkaido. The name was selected among other candidates proposed by children who attended the Fureai Space Festival, held in Kushiro city on the 2007 Japanese Space Day.
