Ikeda Tsuneoki (1536 – May 18, 1584), also known as Ikeda Nobuteru, was a prominent daimyo of the Ikeda clan and a distinguished military commander during Japan's Sengoku and Azuchi-Momoyama periods. He served under the influential warlords Oda Nobunaga and Toyotomi Hideyoshi. Tsuneoki’s connection to Nobunaga began early, as his mother, Yotokuin, was Nobunaga’s wet nurse and later became a concubine to Oda Nobuhide, Nobunaga's father.
Early Life and Background
Tsuneoki’s childhood name is unknown, but he was commonly called Katsuzaburo. His father, Ikeda Tsunetoshi, served Oda Nobuhide. Born in one of several debated provinces (Owari, Mino, Settsu, or Omi), Tsuneoki rose to prominence as one of the four karo (senior retainers) at Kiyosu Castle. He held the title of Kii-no-kami ("Governor of Kii Province") and adopted the courtesy name Shozaburo. Later in life, after becoming a priest, he referred to himself as Shonyū.

He was the third son of Oda Nobunaga, born to a concubine named Sakashi. Nobutaka was referred to as "San Shichi," possibly because he was born on the seventh day of the third month in the Japanese lunar calendar. However, there is a theory suggesting he was born twenty days earlier than his elder brother, Oda Nobukatsu, but due to delays in reporting and the low status of his mother’s family, he was acknowledged as Nobunaga’s third son.
