→Lord of Sanada · Takeda vassal
Sanada Yukitaka (1513–1574), also named Yukitsuna, is the founder of Sanada power in the small valley that gave the family its name, north-east of Ueda. Associated with the Unno network and driven from his lands in 1541, he entered the service of Takeda Shingen around 1544. Where the Takeda army had failed in 1550, he took Toishi Castle in 1551 without an assault, by winning over local lineages, thus opening eastern Shinano to the Takeda. The Sanada mountain castle, known as Sanada Honjō, and the neighbouring residence that he developed with his son Nobutsuna became the heart of the clan, whose fame would be built by his son Masayuki and his grandsons.
The strength of Toishi lies in its position on the eastern spur of the Tarō massif, from which the entire Sanada valley can be watched. After the defeat of 1550, Yukitaka relies on family and local ties: relatives, including his brother Yazawa Tsunayori according to later accounts, and the Kiyono and Terao lineages go over to his side, and the fortress falls in 1551. This blow opens the gate to Ueda for the Sanada.

Perched on a ridge from which almost the whole Sanada valley can be taken in, the Sanada-yama-jō commands the routes to Kōzuke and Matsushiro. It is regarded as the principal seat of the clan after the reconquest, hence its modern name of Sanada Honjō; it is protected as a cultural property of Ueda city, together with the neighbouring lordly residence.
