桶狭間の戦い
During the time of Ikoma Iemune (生駒家宗), the third head of the clan, Inuyama Castle (犬山城) in Owari Province belonged in to Oda Nobuyasu (織田信康). Nobuyasu's nephew Oda Nobunaga (織田信長) began visiting the Ikoma family mansion and approached them for their financial strength and knowledge of the surrounding area. Due to the Battle of Okehazama in 1560 the Ikoma had a brief respite from Nobunaga and were able to conduct business freely in the territory.
