小坂城跡

Shinano Kosaka Castle Yamashiro (573m / 155m) Remains: stone wall, earthworks, Guo, moat Castle owner: Mr. Kuwahara, Mr. Hoshina History: The age of the castle is unknown. According to folklore, it was built by Mr. Kuwahara, a local lord. Mr. Kuwahara belonged to Mr. Akazawa, the owner of Shiozaki Castle, and was in Kosaka Castle, but eventually Mr. Kuwahara took power and Mr. Akazawa declined, and Mr. Kuwahara became the owner of Shiozaki Castle and named him. It is said that Masayoshi Hoshina was in the castle to prepare for Mr. Ogasawara when he became the territory of Takeda in 1553. After the fall of Takeda in Tensho 10 (1582), Uesugi of Echigo invaded, and Sakon Hoshina fell to Uesugi and became Uesugi territory. Description: Kozaka Castle is built at an altitude of 573m, at the top of the tip of a ridge that is derived from Kozakayama at an altitude of 660.8m, which rises to the north behind Ryudoin. The main enclosure is at the top of the tip of the ridge, and a stone wall remains partially. From the west to the south, there are a series of banded and waist-curved rings, but it seems that the area has been cleared and agricultural machinery is scattered around, and the terrain is confusing. The north back of the main enclosure is Horikiri, and the ridge behind it has a small curved ring surrounded by a low earthwork, and there is a Horikiri or a koguchi-shaped dent between them. At the southern end of the northern ridge, there is a small Kuruwa that looks like a sight seeing, and on the ridge that continues north from there, there is a normal Horikiri with six Horikiri, of which Shijo is Ohorikiri. Information: There is a mountain road leading to Kosaka Castle from the graveyard on the south side of Ryudoin. There is another route that goes up the west valley.
