Itami Fusakata served as a bushō during the Sengoku period. He was a retainer of the Noto-Hatakeyama clan. He also had the name of Sōemon and was a member of the Hatakeyama Group of Seven – a political organ comprised of senior retainers of the Noto-Hatakeyama who conducted affairs of the clan by means of a council over a period of years.
At the time of his coming-of-age ceremony, Fusakata received one of the characters in his name from Hatakeyama Yoshifusa, adopting the name of Fusakata. His activities are seen primarily from the period that he served under Hatakeyama Yoshitsugu including service as a clan elder.
In 1553, an internal power-struggle among the senior retainers of the family escalated into armed conflict in the Battle of Ōtsuki-Ichinomiya. Fusakata sided with Yusa Tsugumitsu against Nukui Fusasada, but was killed in action while those supporting Fusasada went on to victory.
