Iwao Kusano (1908-1999) was an orthopedist who contributed greatly to practice and research. As an amateur astronomer, he played an important role in investigating the Yonouzu meteorite, building a monument at the impact site at his own expense. The 30-kilogram stone had fallen near his home on 1837 July 14.Naming citation (20000320/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
