Battle of Dōdō Fort (堂洞合戦 Dōdō Kassen) was a battle centered around Dōdō Fort in Chūnō, Mino Province, that took place on 22 September 1565 between Oda Nobunaga's army and the Kajita clan and Kishi Nobuchika, who was on the side of Saitō Tatsuoki. In July 1565, Satō Tadayoshi, lord of Kajita Castle, got in touch with Nobunaga through Niwa Nagahide. Hearing this, Nobunaga was pleased and sent 50 gold coins to Tadayoshi. However, Saitō Tatsuoki perceived acceptance of Tadayoshi as betrayal towards the Saitō clan. After the Unuma Castle and Sarutaku Castle fell to the Oda forces, and when Sarutaku Castle's commander, Tajimi Shuri-no-Jyo, fled to Kai Province, the defeated troops entered Dodo Castle and joined forces with Kishi clan's forces. In response, Nobunaga sent Kanamori Nagachika as an envoy to Dōdō Fort, asking Kishi Nobuchika to surrender. However, Nobuchika's son, Nobufusa, refused.
