Title: Sagami-no-Kami
Also known as: The Tiger of Sagami, The Lion of Sagami

Son of Houjou Ujitsuna and third head of the Late Houjou Clan, one of the greatest daimyo of the Sengoku in both military and political arenas. He expanded the Houjou holdings to five territories and battled both Takeda Shingen and Uesugi Kenshin over the Kantou and Suruga regions.

He retired in 1560 and handed over the clan to his eldest son Houjou Ujimasa, but continued to guide the clan until his death of palsey or stomach cancer in 1571. He made an alliance with the Takeda Clan in 1562 and gave over his 7th son, Houjou Saburou, to Takeda Shingen for adoption.

Houjou Ujiyasu was a great admirer of poetry, culture and learning as well as a outstanding administrator who created unique bureaucratic organizations such as litigation processes for the ruling of his lands. He was much beloved of his people and widely mourned at his death.
