(10162) Issunboushi Main-belt Asteroid

Discovered on 2 January 1995 by Niijima, T., Urata, T. at Ojima.

The extraordinarily small character Issunboushi---Issun means about 3 cm in old Japanese---was the hero of many old Japanese tales. Born the size of a bean, he defeated ogres, succeeded in a stratagem that got him a beautiful bride, and shook a mallet that instantly transformed him into a normal young man.Naming citation (19991123/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
