Taga Hidetane served as a bushō from the Sengoku to early Edo period.

In 1565, Hidetane was born as the second son of Hori Hideshige.

Hidetane was adopted as a son-in-law of Taga Sadayoshi, a kokujin, or provincial landowner, in the Takashima District of northern Ōmi Province.  In the sixth month of 1582, he joined Akechi Mitsuhide in a coup d’état against Nobunaga known as the Honnō Temple Incident, so he was removed from his position and became a retainer of his older brother, Hori Hidemasa with a fief of 8,000 koku.  He served for a long period as the chamberlain of Sawayama Castle during the absence of his brother.

After the death of Hidemasa, Hidetane served Toyotomi Hidenaga and Toyotomi Hideyoshi, participating in the Battle of Komaki-Nagakute, the Conquest of Odawara, and the Bunroku-Keichō Campaign.  Hidetane acquired landholdings of 20,000 koku in Kaguraoka in Yamato Province.  In 1600, at the Battle of Sekigahara, Hidetane joined the Western Army and participated in the attack on Ōtsu Castle in Ōmi so, after their defeat, he lost his position again.  He turned to his nephew, Hori Hideharu, for support but, in 1610, in the era of Hori Tadatoshi, the Hori clan was removed from its position as daimyō so he became a rōnin, or wandering samurai.  In 1615, at the Siege of Ōsaka, Hidetane associated with the Maeda clan and made contributions for which he was awarded a fief of 6,000 koku by Maeda Toshitsune.

Hidetane died in the eleventh month of 1616.  As members of the Kaga domain, his descendants received a fief of 5,000 koku.  Many generations later, toward the end of the Edo period, Naomasa (the head of the family), was recommended to succeed the Kanamori family of the Sōwa style of tea ceremony, so he retired and dedicated himself to this pursuit.
