Kosa was the son of [[Shonyo Kokyo|Shonyo Kokyô]], the leader of the Shinshû Buddhist sect, who passed away in [[1554]]. Leadership of the [[Ishiyama Honganji]] (Hongan Temple) and [[Kaga province]] passed to Kosa despite his youth with Imperial sanction. In [[1568]] [[Oda Nobunaga]] entered [[Kyoto]], and relations between the [[Oda clan|Oda]] and Honganji quickly soured. In [[1570]] Nobunaga attacked the Honganji, which had become a fortress well stocked with provisions and [[Teppo|firearms]]. Nobunaga's early attempts at a direct assault were repulsed, and he afterwards turned to reducing the Honganji's satellite forts. Kosa in turn called upon the assistance of the [[Mori clan|Môri]] family, who began ferrying in supplies with their powerful Inland Sea navy. The Môri navy was defeated in [[1578]] and the Honganji finally isolated. The siege nonetheless continued into [[1580]]. Finally, in the 7th month of that year, Kosa agreed to surrender after the court's efforts to facilitate a peace. Nobunaga, in a rare show of temperance, accepted the offer. The Ishiyama Honganji complex was to be abandoned but the defenders were given pardon and the Honganji's temples in Kaga, seized by the Oda in the conquest of that province, were to be returned. [[Toyotomi Hideyoshi]] was to make use of Kosa's influence, and dispatched him to [[Kyushu]] to rally his supporters there in expectation of Hideyoshi's [[Kyushu Campaign|invasion]] of that island in [[1587]]. In [[1591]] Hideyoshi permitted Kosa to build a new Honganji facility in Kyoto, which was constructed on three blocks in the southern part of the city.
