The Battle of Inō took place during the Sengoku period (16th century) of Japan.

[1] The three conspirators were defeated at the Battle of Inō, but they were pardoned after the intervention of Tsuchida Gozen, the birth mother of both Nobunaga and Nobuyuki.

Nobuyuki began his second rebellion in 1557, but was defeated and his Suemori Castle was destroyed by Nobunaga's retainer Ikeda Nobuteru.

When Nobunaga was informed of this by Shibata Katsuie, he faked illness to get close to Nobuyuki and assassinated him in Kiyosu Castle.
