Takesetsu Old Castle is called “Old Castle” to distinguish it from the later-built Takesetsu Castle (Takesetsu New Castle). The two castles are located in close proximity and are important for understanding the castle history of the Takesetsu region.
History and Lords of Takesetsu Old Castle
The Yamada Clan’s Residence Period
The exact construction date of Takesetsu Old Castle is unclear, but it is believed to have been built in the late Muromachi period by the Yamada clan, a powerful local family. The Yamada clan were local lords who maintained a certain level of power in the mountainous region of Mikawa Province, controlling the surrounding area from their base at Takesetsu Old Castle.
The mountainous region of Mikawa Province was a border area with Shinano and Mino Provinces, and a strategically important transportation hub. It is presumed that Takesetsu Old Castle utilized these geographical conditions to function as a base for monitoring roads and managing the territory.
The Advance of the Suganuma Clan and the Construction of Takesetsu Castle
In the mid-Sengoku period, the power of the Tamamine Suganuma clan, a powerful local lord in eastern Mikawa, began to encroach on the Takesetsu region. It is believed that by the time Suganuma Sadanobu built the new Takesetsu Castle (Takesetsu New Castle), the Yamada clan had also submitted to them.
It is presumed that Suganuma Sadanobu built the new Takesetsu Castle in a more defensible location, and that Takesetsu Old Castle shifted its role to a forward base or subsidiary castle. During this period, the mountainous region of Mikawa was a turbulent era, with various powers such as the Matsudaira, Suganuma, and Okudaira clans intricately intertwined, and the area also facing invasions from the Takeda clan.
Abandonment of the Castle and its Aftermath
It is unclear exactly when Takesetsu Old Castle was abandoned, but it is believed that its role gradually ended after it began to function fully. In the Edo period, its function as a castle was completely lost, and the land was used for farming and forestry.
