Battle of Ukino (July 12, 1558) was the final victory of Oda Nobunaga in his struggle to unite the province of Owari against his cousin, Oda Nobukata, deputy governor of northern Owari.

Background

Places in the provinces of Owari and Mikawa around 1558 on the map of Aichi Prefecture. Places under the control of Oda Nobunaga are marked in red.

After defeating Imigawa clan of Suruga in the battle of Muraki and capturing southern provincial capital of Kiyosu (both in 1554), Oda Nobunaga united the Southern Owari under his rule. After resolving internal struggle and rebellion in his own family, defeating his younger brother Oda Nobuyuki in the battle of Ino (in 1556), Nobunaga was firmly established as the ruler of the southern Owari, while the northern part of the province was still the domain of his cousin, Oda Nobukata of Iwakura castle, deputy governor of the northern Owari. In 1555, Saitō Dōsan, Nobunaga's father in law and ally, retired as the lord of Mino Province (north of Owari) for his eldest son, Saitō Yoshitatsu. However, on January 4, 1556. Yoshitatsu killed his two brothers, leading to a military conflict with his father. Nobunaga supported Dōsan, but Yoshitatsu defeated and killed him in battle in April 1556.

Battle

Seeing the fall of Nobunaga's father in law as an opportunity, Oda Nobukata of Iwakura Castle concluded a pact with Yoshitatsu and opened hostilities against Nobunaga. Nobunaga with support of his cousin, Oda Nobukiyo of Inuyama, defeated the forces of the Oda Nobukata of Iwakura at Ukino in Owari on August 24, 1558 (Japanese calendar date: Eiroku era: 1st year, 7th month, 12th day). as result, Oda Nobukata retreat to Iwakura Castle.

Aftermath

In 1559, Nobunaga besieged, captured, and razed Iwakura Castle to the ground, ending the Iwakura branch of the Oda family and finally uniting the whole province of Owari under his rule. Later that year Nobunaga visited Kyoto and was received by Shogun Ashikaga Yoshiteru, gaining the formal appointment of deputy governor (shugodai) of Owari.
