Rairen played a role in the peace treaty with Nobunaga and later moved to the region of Tenmangū to serve Honganji Kennyo and Hideyoshi.
At that time, Yoritan was one of the people sent to Gansho-ji Temple in Ise Province by Kennyo's order to provide guidance on the ground.
Yoritan was one of the monks who had been given high authority, and when he entered Nagashima, he led his followers together with Shimotsuma Yorinari and attacked Furukie Castle in Owari, which was defended by Oda Nobuoki (Nobunaga's younger brother), on November 21 of the same year, with a large army that was joined by the Hattori clan of Yatomi, Owari, and local farmers, and defeated Nobuoki, bringing Furukie Castle under his control.
In the third invasion of Nagashima in 1574, the Oda forces, totaling 80,000 men, besieged each fort individually, cutting off cooperation and leaving them with no option but to siege.
However, this was a plot by Nobunaga, and on September 29th, when Yoritan left the castle to surrender it, he was shot dead along with his followers in the vicinity by a volley of gunfire from the Oda forces.
