Magome Castle (Ota Ward, Tokyo) Complete Guide | Exploring the History of a Sengoku Period Castle and the Kajiwara Clan
Magome Castle, located in Minami-Magome, Ota Ward, Tokyo, was a medieval castle ruled by a vassal of the Later Hojo clan during the Sengoku period. While very few remains today, it is known as an important historical site indispensable to understanding the history of Ota Ward. This article provides a detailed explanation of this valuable castle site, from its historical background and structure to its current estimated location, access methods, and surrounding attractions.
What is Magome Castle? | A Medieval Castle in Ota Ward, Tokyo
Magome Castle was a castle from the Sengoku period located in the Minami-Magome area of Ota Ward, Tokyo. It cleverly utilized the topography of a tongue-shaped plateau, functioning as a natural stronghold surrounded by steep cliffs and swamps. It is estimated that the castle grounds encompassed a vast area spanning the present-day Minami-Magome and Naka-Magome regions.
Magome Castle, a medieval castle, possessed the typical form of a flatland castle and was one of the important strongholds indicating the sphere of influence of the Later Hojo clan in Musashi Province. As one of the few remaining medieval castle ruins in the heart of Tokyo, it is a historical site of great historical value.
Location and Topographical Characteristics of Magome Castle
Magome Castle was built on the tip of a tongue-shaped plateau located at the southern end of the Musashino Plateau. This terrain was extremely advantageous for defense, surrounded on three sides by steep cliffs, with a marshland at the bottom of the valley. It was a natural fortress, effectively blocking enemy invasions with its natural terrain.
From the plateau, one could survey the surrounding area, serving as a lookout point to detect enemy movements early. This topographical advantage is one of the reasons why Magome Castle functioned as an important base throughout the Sengoku period (Warring States period).
History of Magome Castle | The Era of Kajiwara Sukegoro and the Later Hojo Clan
About the Castle Lord, Kajiwara Sukegoro Mikawa-no-kami
The lord of Magome Castle is known as Kajiwara Sukegoro Mikawa-no-kami. The Kajiwara clan claimed descent from Kajiwara Kagetoki, a powerful retainer during the Kamakura period, and served the Later Hojo clan during the Sengoku period.
According to the Hojo clan’s land register, Kajiwara Sukegoro’s fiefdom was 32 kan 60 mon. This was a medium-sized territory among the Later Hojo clan’s retainers, but given that he was entrusted with an important area close to Edo Castle, it is thought that he enjoyed the Hojo clan’s trust.
Magome Village under the Rule of the Later Hojo Clan
Magome Village belonged to the Edo Castle territory, but in the late Sengoku period, Hojo Ujimasa directly controlled the Edo Castle territory. Therefore, records show that the villagers of Magome Village were sometimes sent to distant Odawara and Hakone for labor.
During this period, Magome played a crucial military and administrative role as one of the important bases within the sphere of influence of the Later Hojo clan. Located along the road connecting Edo Castle and Odawara Castle, it is believed to have also functioned as a vital transportation hub.
Magome Castle After the Fall of the Hojo Clan
In 1590 (Tensho 18), with the fall of the Later Hojo clan following Toyotomi Hideyoshi’s siege of Odawara, Magome Castle ceased to function. After Tokugawa Ieyasu’s entry into Edo, this area developed as a suburb of Edo.
After losing its function as a castle, the plateau of Magome was gradually converted into farmland and residential areas. Throughout the Edo period, traces of the former castle gradually disappeared.
Magome Castle Grounds and Structure | A Medieval Castle on a Vast Plateau
Estimated Extent of the Castle Grounds
According to official information from Ota Ward, the grounds of Magome Castle were vast, extending as follows:
- East: Up to Kitano Shrine (Minami-Magome 2-chome)
- West: Up to Yudono Shrine (Minami-Magome 5-chome)
- South: Up to Usuda-zaka-shita (Chuo 1-chome, Chuo 4-chome)
- North: Up to Ota City Magome Library (Naka-Magome 2-chome)
This area spanned approximately 800 meters east-west and 600 meters north-south, indicating that it was a considerably large medieval castle. In terms of current addresses, the castle grounds covered a wide area from Minami-Magome to Naka-Magome.
Castle Defense Structure
The defenses of Magome Castle primarily utilized the natural terrain:
- Steep Cliffs: Steep cliffs surrounding the plateau physically hindered enemy incursions.
- Marshland at the Bottom of the Valley: Marshes were strategically placed in the valleys below the cliffs, forming an additional defensive line.
- Watchtower on the Plateau: The elevated position allowed for wide-area surveillance.
- Limited Access Routes: Limiting access routes to the plateau allowed for concentrated defense.
Through these multi-layered defensive structures, Magome Castle possessed strong resistance against enemy invasions.
Existing Remains
Unfortunately, the area around Magome is now entirely residential, and no clear castle remains have been identified. Typical castle structures such as moats, earthworks, and baileys have been lost.
However, the topography itself hasn’t changed significantly, and walking along the edge of the plateau, you can still sense the remnants of the former steep cliffs. Furthermore, it’s possible to discern topographical features from the castle era, such as slopes and valleys.
