Hatakeyama Yoshitaka served as a sengoku daimyō of Noto. He was the eleventh head of the Hatakeyama clan. Yoshitaka was the second son of Hatakeyama Yoshitsuna, the ninth head of the clan.
In 1566, after his father (Yoshitsuna) and grandfather (Yoshitsugu) were expelled by senior retainers from Noto, and his older brother (Yoshinori) inherited the headship of the clan, Yoshitaka was said to have adopted the Nihonmatsu surname and served as a deputy to his older brother. There is a question, however, whether he actually served in this role given his young age at the time.
In 1574, after the sudden death of Yoshinori, Yoshitaka succeeded him as the eleventh head of the clan. Meanwhile, in 1576, Yoshitaka himself appeared to have suddenly died. According to one theory, he may have been poisoned by senior retainers, but this may be confused with the poisoning of Yoshinori. The clan was then inherited by Hatakeyama Haruōmaru while still a child.
The name of Yoshitaka does not appear in authenticated sources, so there is a theory that he was the same individual as Yoshinori. Nevertheless, records of the Uesugi family include references to Yoshitaka so the possibility that this was a separate person cannot be refuted.
A letter from Uesugi Kenshin to Hōjō Takahiro notes that Yoshitaka’s wife was given to Kagehiro, so there is a theory that the widow of Yoshitaka wed Hōjō Kagehiro, a retainer of the Uesugi clan.
