6744 Komoda           Discovered 1994 May 6 by K. Endate and K. Watanabe at Kitami.
Named in memory of Kazuyoshi Komoda (1915-1967), amateur astronomer in Japan. Though handicapped by poliomyelitis, he enthusiastically observed Jupiter from 1944 to 1961. Name proposed by the discoverers following a suggestion by T. Sato, I. Hirabayashi and A. Fujii.
