Saneatsu Mushanokoji (???? ??(??), Mushanokoji Saneatsu, 12 May 1885 – 9 April 1976) was a Japanese novelist, playwright, poet, artist, and philosopher active during the late Taisho and Showa periods of Japan.
Later on in life he requested that the pronunciation of his surname (as far as was concerned) be changed from the usual Mushanokoji, to Mushakoji, but without much success.
He was nicknamed Musha and Futo-o by his colleagues.
