Children: Isono Kazutsugu (adopted son of Isono Kazumasa)
Anyōji Ujitane was a bushi from the Sengoku to early Edo period. He served as a retainer of the Azai clan.
The Anyōji clan were dogō, or wealthy landowners in Ōmi Province. Originally, the clan served the Kyōgoku clan, the military governors of Ōmi.
Ujitane was born as the son of Anyōji Saburōzaemon Ujihide. There is an unsubstantiated theory that he served as an intermediary to arrange for the marriage between his lord, Azai Nagamasa, and the younger sister of Oda Nobunaga, Oichi-no-kata.
At the Battle of Anegawa, which erupted on 6/28 of Genki 1 (1570), Ujitane became a prisoner of the Oda army but was recognized for providing advice to Nobunaga in regard to mistakes with respect to the pursuit of Azai forces and was released.
After the decimation of the Azai family, he served Kyōgoku Takatsugu. He died in 1606.
