Toshio Akiyama (b. 1929) popularized the wind symphony in Japan and became Japan's foremost conductor of wind orchestras. He founded the Sony Concert Band in 1957 and conducted it for over four decades. In retirement, he has conducted his hometown Omiya Wind Symphony, whose June 2025 concert with the Honolulu Wind Ensemble is the occasion for this naming.Naming citation (WGSBN Bull. 5, #11, 13), IAU / Minor Planet Center, via NASA/JPL
