Named in honor of Yohko Miyamoto (b. 1922), wife of the amateur astronomer Yukio Miyamoto. Mrs. Miyamoto has assisted her husband in his work, directly and indirectly, for half a century. Her sage advice to young members of the Kumamoto Astronomical Society was beneficial to the discoverer in his youth.Naming citation (19961224/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
