Also known as: Fujita Awa-no-Kami (藤田安房守), Fujita Ujikuni (藤田氏邦)
Title: Awa-no-Kami

Houjou Ujikuni was the fourth-born son of Houjou Ujiyasu (third son to survive childhood), younger brother of Houjou Ujimasa and Houjou Ujiteru, and older brother of Houjou Ujinori, Houjou Ujitada, Houjou Saburou (Uesugi Kagetora), and Houjou Ujimitsu.

He married Ofukugozen, daughter of Fujita Yasukuni of Musashi (a vassal of the Houjou Clan who had years before submitted under attack) and was adopted as heir to the Fujita Clan. He later adopted his older brother Ujimasa's 6th son, Houjou Naosada.

Like his brother Ujiteru, Ujikuni was known for his courage and wise governance. He was entrusted with the military affairs of the front line of the North Kantou, Kouduke-no-kuni and distinguished himself in battles leading to the expansion of the Houjou territory, though was defeated at the Battle of Mimasetoge in 1569 by Shingen.

Ujikuni's quick temper was said to be one of the contributing factors to the fall of the Houjou Clan. In 1578, he poisoned his brother-in-law Fujita Juuren to ensure his own position, thus earning the hatred of his other brother-in-law, Fujita Nobuyoshi, who entered the service of Takeda Katsuyori and later Uesugi Kagekatsu.

When Odawara Castle fell to Toyotomi Hideyoshi in the Siege of Odawara in 1590, Ujikuni cut off his hair and begged for his life, which he was granted with a fief of 1000 koku in Noto. He lived until the age of 57, when he died of illness at Kanazawa in Kaga (there are also theories that he killed himself).
