The castle was originally commissioned by Makino Kohaku in 1505.
It is historically known as Imabashi Castle, named after its location in the Imahashi district.
During the Edo period, the castle was held by a succession of 14 different daimyo families.
The stone walls surrounding the site are constructed in the 'nozura-zumi' style, utilizing unhewn stones stacked without mortar.
The castle site is situated at the southern end of the Toyohashi Park complex, which also contains the Toyohashi City Art Museum.
The turret is built of reinforced concrete to mimic the exterior appearance of the original structure rather than using historical timber-frame techniques.
Yoshida Castle Iron Turret (Tetsuyagura) serves as the primary reconstructed landmark within the Yoshida Castle ruins in Toyohashi Park. The current structure was reconstructed in 1954 to represent the castle's historical presence despite the site's original 16th-century complex remaining largely unfinished. The castle was historically a crucial stronghold for the Tokugawa clan, guarding the strategic passage between the Mikawa and Totomi provinces. The site features stone walls and moats dating back to the late 16th century. Visitors can access an observation deck within the turret that offers views of the Toyo River and the surrounding park. The interior functions as a local history museum housing documents, armor, and artifacts related to the castle's administrative history. It is the only turret structure currently rebuilt on the original foundation.

Combine your visit with a walk through the adjacent Toyohashi Park, especially during cherry blossom season.
Spend time examining the stone wall foundations, which are the most authentic remaining elements of the original site.
The observation deck provides a clear vantage point for photographers to capture the Toyo River landscape.
Do not mistake the modern concrete reconstruction for a 16th-century original; appreciate it instead as an interpretative site.
