8432 Tamakasuga           Discovered 1997 Dec. 27 by A. Nakamura at Kuma Kogen.
Named in honor of Ryoji Matsumoto (b. 1972), Japanese sumo wrestler whose professional name is Tamakasuga. Born in Ehime prefecture, where this minor planet was discovered, he became a professional wrestler in 1994. In 1996 he was promoted to "Makunouchi", the top division in the official listing of rank. Famous for his powerful "tsuki-oshi", or pushing-thrusting style, Tamakasuga has won the Outstanding Performance Award, the Technique Prize and the Fighting Spirit Prize (twice) in his 26 tournaments.
