Shimura Castle Ruins - Itabashi City

An environment-friendly shrine surrounded by kindergartens and nursery schools. The approach is a long walk, a good power spot for forest bathing!

At the entrance of the shrine is a stone monument of the castle ruins. The shrine itself seems to be a castle ruin, and the back of the shrine is quite steep. You can also see the city.

Now it is Kumano Shrine and Shimura Elementary School. A monument to the ruins of Shimura Castle stands on the grounds of the shrine.

An empty moat remains on the side of Kumano Shrine to the extent of traces.

It is said that he made the hills of this neighborhood with many slopes a castle. Originally, there was a Kumano Shrine where a castle was later built, and the shrine was used as a guardian of the castle. There is an explanation that the west side of the main shrine is Karabori, and you can see the actual depression.

It is a large castle site about 300m east-west to 200m north-south from Shiroyama-dori to Shimurajoyama Park, and from Onarizuka-dori to Vios Garden Shiroyama, but it is almost developed and the remains can be observed only around the back of the main shrine of Kumano Shrine. However, a solid empty moat and earthworks remain ♡. An observation path is set up from the top of Shimurajoyama Park, but it is usually locked.

A castle that was built by Mr. Shimura. It exists on a ⊂-shaped tongue-shaped plateau sandwiched between the Arakawa and Idei rivers. In the late Edo period geography "Shinpen Musashi Fudoki Manuscript", "Shimura Castle. Located on the western border of the village. The area is 160m. It is on a hill, covered with several old pine trees, and Kumano Gongen is enshrined. Yes ... * " a. Since it is on the east side, is it around Nidec Copal Corporation? I looked around, but there was nothing like that. In addition, on the local information board, the area where the condominium is currently built is the main circle, and the precincts are the remains of the west circle. It is said that there is a remnant of the castle between the main enclosure and the west circle. This may be based on archaeological research. When you actually see it, you can certainly see a land like a hollow. The north side of the precincts is still a steep slope, which is a natural earthwork. In addition, according to "History of Itabashi Ward", the theory that the remains are understood as the main three or two main walls is introduced, but it seems that it is not certain which one. The history of the castle is in the middle of the Muromachi period. The confrontation between Mr. Ashikaga Shigeuji, who oversees the Bando samurai, and Noritada Uesugi, who was the assistant and supervisor of the Kanto region, intensified. Finally, in December 1454, Shigeuji Ashikaga called Noritada Uesugi to the Imperial Palace and killed him. As a result, a war broke out that divided the Bando samurai by the Kantō Kubō vs. the Kanto region (Kyotoku Incident). This aftermath extended to Mr. Chiba, who was a famous family on the Boso Peninsula, and split into Mr. Chiba of the Kantō Kubō and Mr. Chiba of the Kanto region. Mr. Chiba, who is in the Kanto region, has been defeated by Mr. Chiba, who is in the Kantō Kubō, and has fallen to the area around the 23 wards of Tokyo. This is what happened in 1456. At this time, it seems that he received the support of the Kanto administration, and entered the castles such as Obama Castle, Akatsuka Castle, and Shimura Castle on the northern edge of the current 23 wards. It is said that a person named Nobuyoshi Chiba entered Shimura Castle. About 70 years later, the 4th year of Daiei (1524). In the Kanto region, which was confused by the Kyotoku Incident, Mr. Gohojo of Odawara began to stand out. Mr. Gohojo The second generation of the Ujitsu line went north to the southern part of the Kanto region with the aim of conquering the Kanto region. As a result, he entered into a battle with Mr. Uesugi, the Kanto governor who controlled it, around the current Shinagawa station (Battle of Takanawahara). Of course, Mr. Chiba, who controlled the area around Shimura Castle, seems to have arrived on the side of Mr. Uesugi. The Uesugi group, who lost this battle, fall from Edo Castle to Kawagoe Castle. Ujitsu also pursues this. Then, an avalanche falls into Shimura Castle, which was on the way, and it falls. As a result, Mr. Musashi Chiba was destroyed. It is said that the Hojo group set up a camp near the current 5-chome, Maeno-cho before attacking *. After this war, Shimura Castle is said to have been owned by Mr. Gohojo, but he shared his fate with Mr. Hojo due to the conquest of Odawara. The trend of Mr. Shimura, the descendant of Shimura Castle, seems to be unknown after the Kyotoku Incident, but there seems to be a record of being a vassal of Mr. Gohojo, so he was able to go around the Muromachi Warring States period well. It is like. "New Musashi Fudoki Manuscript" * Located on the western border of the village, in Hirosakata Ichimachi, a half-high 處, several old pine trees flourish, and Kumano Gongen sits in the eastern part of the moat. * Maenomura …… Ichiyozuka …… It is in the middle of the village, and it is the name of the reason why he built this mound within one night and finally attacked his castle.

If you head toward Shiroyama Park from Shimura Sanchome Station on the Toei Mita Line, you will see a high cliff. The ruins of Shimura Castle are on this cliff. If you go up a steep slope and dive into the torii gate of Kumano Shrine, you will find the monument of Shimura Castle. The location of Kumano Shrine will be the site of Ninomaru. If you enter the area where the trees on the west side of the worship hall of Kumano Shrine are growing, you can see the moat traces and earthworks between Honmaru and Ninomaru, which are the only remains. A large condominium is built on the site of Honmaru, and no remains remain.
