7954 Kitao           Discovered 1993 Sept. 19 by K. Endate and K. Watanabe at Kitami.
Named in honor of Koichi Kitao (b. 1953), Japanese amateur astronomer and director of the folklore section of the Oriental Astronomical Association. He is a winner of the I. Yamamoto Award (O.A.A.) and the S. Kaho Award (Japan Amateur Astronomical Conference) for his extensive studies of dialectal atar names and star-related folklore. Name proposed by the discoverers following a suggestion by S. Kuwabara, T. Sato and A. Fujii.
