Named in memory of Masamitsu Yamasaki (1886–1959), who worked at the International Latitude Observatory in Mizusawa {see planet  (7530)}. As a codiscoverer of comet 27P/Crommelin (then named Pons-Coggia-Winnecke-Forbes) in 1928, he was the first Japanese to receive the Astronomical Society of the Pacific’s Donohoe medal. (M 30798) _ _.
