is the remains of a fortified residence of the Sanada clan in Ueda, Nagano Prefecture, Japan. The site is believed that it was a main bastion of the Sanada clan until Sanada Masayuki moved their base to Ueda Castle in 1585.[1]
Sanada-shi Yakata was considered unsuitable for withstanding a siege and Sanada clan had such castles as Sanada-shi Honjō Castle and Tenpaku Castle near the residence.[2]
Its ruins have been protected as a Prefectural Historic Sites.[3] The residence is now only ruins, with some stone walls, moats, and earthworks.[1] Kōtai Shrine which was built by Sanada Masayuki when Sanada clan left the residence is on site.[4] Sanada clan Historical Museum is adjacent to the site.[5] [6]
