Terumasa was the 2nd son and heir of Ikeda Nobuteru, Terumasa held Ikejiri Castle (Mino Province) and joined his father in fighting for Hideyoshi in the Battle of Komaki and Nagakute 1584, he led troops at Nagakute, the battle in which his father was killed.

In 1590, following the transfer of Tokugawa Ieyasu to the Kanto, Terumasa was established at Yoshida in Mikawa, a 152,000-koku fief. In 1594 Terumasa married one of Tokugawa's daughters, and after Hideyoshi's death in 1598, the Ikeda drifted into Ieyasu's camp.

When the Sekigahara Campaign began in the fall of 1600, Terumasa immediately sided with his father-in-law, Tokugawa.[1] On 28 September he competed with Fukushima Masanori to be the first to attack Gifu Castle, held by Oda Hidenobu. At the Battle of Sekigahara, Ikeda commanded 4,560 troops[1] in the rear guard and saw some desultory fighting with Chosokabe Morichika's contingent as the battle wound down.

Following the Tokugawa victory, Terumasa was given a 520,000-koku fief and the province of Harima.[2] He expanded the Himeji Castle, which he completed in 1609.[3] In 1603 Bizen was added to Terumasa's territory, and this he assigned to his eldest son, Toshitaka (1584–1616).

By the time of Terumasa's death in 1613, the Ikeda had grown to rule over Harima, Bizen, Inaba, and Awaji, with a combined income of around 1,000,000-koku. Following the death of Toshitaka, the Tokugawa Bakufu took steps to reduce the alarming power of the Ikeda and eventually reduced the family to Tottori (Inaba) and Okayama (Bizen).
