Fumitane was the daimyô of the Akizuki house during the mid-16th Century. He became a retainer of Ôuchi Yoshitaka in 1541 but after Yoshitaka's death he became a vassal of the Ôtomo. In 1557, having formed relations with the Môri, he rebelled, only to be attacked by a 20,000-man Ôtomo army commanded by Tachibana Dôsetsu and Usuki Akihaya. He committed suicide along with his eldest son Harutane on 6/8/1557 but his second son Tanezane was taken into the protection of the Môri.
