Kokie Castle is said to have been built by Oda Nobunaga's fourth brother, Oda Hikoshichiro Nobuoki, during the Eiroku era and was placed there to suppress the Ikko sect of Buddhism in Nagashima, Ise.

In September 1570, when the Battle of Ishiyama began between Hongan-ji and Nobunaga, followers of the Hongan-ji Temple also rose up in revolt in Nagashima. After taking Nagashima Castle, the followers attacked Furukie Castle on November 16. Nobuoki requested reinforcements from Nobunaga and Takigawa Kazumasu of Kuwana Castle, but Nobunaga was held up in Otsu by the forces of Azai Nagamasa and Asakura Yoshikage and the monks of Enryaku-ji Temple (the Siege of Shiga), and Kazumasu, who was besieged by the Ikko sect, was unable to send reinforcements. Six days later, on November 21, Furukie Castle fell. According to the Shincho Koki, Nobuoki climbed onto the tower and committed suicide, but local legend has it that he was killed outside the castle. The castle was subsequently abandoned.

The area around where the castle is said to have stood is now farmland (lotus root fields), and no remains remain. The layout of the castle is also unknown. Tomioka Shrine, which is located on the site, is thought to have been placed there as the guardian deity of the castle.
