Fukunohana Koichi (born 1 July 1940 as Koichi Fukushima) is a former sumo wrestler from Kōshi, Kumamoto, Japan. He made his professional debut in January 1958 and reached the top division in September 1965. His highest rank was sekiwake. He retired in November 1975. He had been scheduled to fight Kashiwado in July 1969 and Taihō in May 1971, but on both occasions received a fusensho or win by default because the yokozuna both announced their retirements. Fukunohana had never beaten Taihō in the ring, losing to him ten straight times.
