Kutsuki Tanetsuna served as a bushō during the Sengoku period. He was a kokujin, or provincial landowner, in Kutsukidani in Ōmi Province. Tanetsuna was born as the son of Kutsuki Kihide. He held the title of Assistant Vice-Minister of Popular Affairs.
His birth year is unknown but he first appears in records of the Kutsuki family in 1505 under the childhood name of Takematsu. This was a communication from Matsuda Yoriakira and Iio Motoyuki, magistrates for the Muromachi bakufu.
The year of his coming-of-age ceremony is unknown, but, in 1516, similar to his father, Kihide, he received one of the characters from the name of Ashikaga Yoshitane (the tenth shōgun of the Muromachi bakufu) and adopted the name of Tanehiro. In 1522, he changed his name to Tanetsuna.
Early in the Eishō era (1504 to 1521) Tanetsuna served as a guard of the shōgun residence as a member of the hōkōshū, the military organ under the direct control of the shōgun. In 1525, during an invasion against the Azai clan of northern Ōmi, he served in the vanguard for the army of Rokkaku Sadayori, the vice-deputy shōgun of the bakufu, military governor of Ōmi, and sengoku daimyō of southern Ōmi.
In 1527, Tanetsuna was the head of the Kutsuki clan when Ashikaga Yoshiharu (the twelfth shōgun) and Ashikaga Yoshiteru (his son and the thirteenth shōgun) fled from Kyōto to Kutsukidani in Ōmi after being ousted by the Miyoshi clan of Awa Province. Yoshiharu served as the shōgun from 1521 to 1546. During the 1530’s and 40’s, Tanetsuna served as a member of the naidanshū, a group closely associated with the shōgun serving as a deliberative council with respect to governing affairs. In the era of Ashikaga Yoshiteru, Tanetsuna served as a member of the otomoshū, a group of close associates who accompanied the shōgun on excursions.
Tanetsuna engaged in disputes with the Kyōgoku and Rokkaku clans of Ōmi and maintained his independence. However, as Rokkaku Sadayori expanded his influence, Tanetsuna was compelled to submit to his command.
The year of his death is unknown. Tanetsuna last appears in records of the Kutsuki in 1549, but there is also a theory that he appears in sources from 1562, so it is possible that he lived into the 1560’s.
