The main castle is immediately if it climbs to the whetstone castle. The territory was made stepwise, and I recalled Mr. Asai's Odani Castle.

There are many Yamashiro ruins in the Ueda and Ogata districts, but no other castle like the Whetstone castle ruins has been confronted four times during the Warring States period. In addition, Whetstone Castle is a Yamashiro that is extremely important for the development of Mr. Sanada. Shingen Takeda from Kai (Yamanashi Prefecture) in 1550 (Astronomy 19) attacked the Whetstone Castle protected by Yoshikiyo Murakami (owner of Katsurao of Sakashiro) with a large army for more than a month. I couldn't capture it because of Yamashiro, but I was defeated. The following year, Yukitaka Sanada, who is under Takeda, hijacked Whetstone Castle due to his good strategy. Then, during the first Ueda battle in 1585, Masayuki's eldest son, Nobuyuki (no), was guarding the important stone stone castle behind Ueda Castle. During the second Ueda battle in the 1600th year of Keicho, Masayuki's second son, Nobutushige (Yukimura) stayed up, but his brother, Nobuyuki, who was on his side in Tokugawa later entered the castle. In this way, the whetstone castle that held the northern half of the Ueda Basin became a battleground between Murakami, Takeda, Sanada, and Tokugawa. The whetstone castle ruins were built using the ridge of Higashitaro Mountain that rises in the northeast of the Ueda Basin. It is a large-scale group of Yamashiro that spans the three settlements of Hatayama, Iseyama, and Kongoji Temple. There are Masugata Castle in the north, the Toishi Castle in the south, and Yoneyama Castle in the southwest. The four castles are collectively called the whetstone and Yoneyama Castle Ruins. Honjo-From Yoseiji Temple in front of Iseyama, pass through a place called Uchigoya, Mizute, and climb a curved slope to reach Honjo. Masugata Castle-From Honjo, take the Yake bamboo ridge road 120m north, and you can see the Sanada area at an altitude of 800m. Toshijo Castle-Built 140m south of the main castle, also using natural mountain peaks, there is a 9m wide excavation on the north side. From here, you can see Ueda city, Shioda, eastern part, and Saku area best. Yoneyama Castle-Go down the steep slope to the southwest from Whetstone Castle, and the peak in front of the depression called "Baba" is the castle ruins. There is a village of Kongoji Temple in the western valley, and the place names that are often found in the ruins of castles, such as the entrance of a castle and a hut, are left. Yoneyama Castle said that the horse's back was washed with white rice in order to show to the enemy that black rice burned in the war was unearthed and that there was a lot of water in the castle when it was in the water stop of the enemy It is also famous for having the legend of Shiromai Castle.
