Takeda Nobuaki served as a bushō during the Sengoku period.  Nobuaki was a retainer of the Miyoshi and Chōsokabe clans and served as the lord of Waki Castle in Awa Province.

There is a legend that Nobuaki was an illegitimate son of Takeda Nobutora, a sengoku daimyō and the fifteenth head of the Takeda clan of Kai Province.  If this is true, then Nobuaki would have been a younger brother of a different mother of Takeda Shingen.  In 1541, Shingen and retainers of the Kai-Takeda ousted Nobutora who then resided under the protection of Imagawa Yoshimoto in the neighboring province of Suruga.  Nobutora raised Nobuaki while exiled in Suruga.

In the third month of 1556, through the offices of Miyoshi Nagayoshi, Nobuaki was invited from Yamato Province and became the lord of Waki Castle in Awa.  Nagayoshi constructed Waki Castle in 1533 and, by 1556, Miyoshi Kanenori (a member of Nagayoshi’s family) had been assigned to serve as the lord of Waki Castle with responsibility to defend northern Awa.  Naganori served as the lord for over twenty years, during which time he focused on civil affairs and the development of the town of Waki below the castle.  His advanced age made it difficult to continue to carry-out his duties so Nobuaki was appointed to replace him.

Takeda Nobutsuna, the lord of Kuwano Castle in the Naka District of Awa is also surmised to have originated from the Kai-Takeda clan.

After the death of Nagayoshi in 1564, Nobuaki served Miyoshi Nagaharu, the son of Miyoshi Jikkyū.

In 1578, Nobuaki, along with Miyoshi Yasuyoshi (the son of Miyoshi Yasunaga) from a neighboring castle, surrendered in front of an invasion by Chōsokabe Motochika.  Later, after Oda Nobunaga commenced an invasion of Shikoku, Yasunaga persuaded Nobuaki to abandon the Chōsokabe and re-join the Miyoshi.  On 6/2 of Tenshō 10 (1582), Nobunaga unexpectedly died in a coup d’état known as the Honnō Temple Incident.  This created an opportunity in the eighth month for the Chōsokabe army to invade Awa again.  On 8/17, the Chōsokabe army with 3,000 troops (or, according to another theory, 12,000 troops) attacked Waki Castle defended by Nobuaki and a garrison of only 500 soldiers.  The defenders withstood a ferocious assault for five days.  On 8/22, Nobuaki fled the castle and after traversing the Asan mountains, entered Sanuki Province, but forces from the Chōsokabe army engaged in a pursuit later killed him in the Ōkawa District of Sanuki.  His remains were buried by a retainer named Ōtsuka Zendayū at the nearby Tōshō Temple.

Nobuaki’s son, Takeda Nobusada, did not accompany him and remained at Waki Castle.  He took his life at the age of sixteen.
