Yoshida Castle occupies a distinctive position as a flatland fortress situated on the banks of the Toyo River in Toyohashi, Aichi Prefecture. Originally established in 1505, this castle exemplifies the flatland castle type and represents an important castle variant in Japan's architectural and strategic repertoire.

The fortress gained prominence under the leadership of Ikeda Terumasa, a notable military figure who significantly expanded and enhanced the castle's facilities and defenses during the late sixteenth century. His improvements made the castle a more formidable military installation while also reflecting the changing nature of castle construction as feudal Japan moved toward a more centralized power structure.

The reconstructed corner turret that stands today in the riverside park serves as the primary visible reminder of the castle's former grandeur and complexity. This turret provides excellent views of the Toyo River and the surrounding landscape, allowing visitors to appreciate both the architectural achievement and the strategic importance of the riverside location.

The castle park setting offers visitors an accessible way to explore the historical site while enjoying the natural beauty of the riverside environment. The turret's architectural style reflects the practical defense needs of the period while demonstrating the aesthetic values that Japanese castle builders incorporated into their work.

Yoshida Castle is recognized as one of Japan's second 100 castles as designated by the Japan Castle Foundation, a distinction that highlights its historical and architectural importance among the hundreds of castle sites across the country. As a flatland castle, its design reflects the defensive priorities and construction techniques of its era, with origins dating to 1505. Visitors traveling to Aichi Prefecture can explore the site alongside other regional historical attractions.

The count of twelve surviving keeps is stated independently by the official sites of Matsue, Maruoka, Matsuyama and Bitchu Matsuyama (checked 2026-09-04). Each of the twelve carries its own source on its own page. The classification line below it is this site's own grouping, not an official designation. The designated properties below it come from the Agency for Cultural Affairs national database of designated cultural properties (国指定文化財等データベース), retrieved 2026-08-13. A missing line means no entry was found in that database — not that the property is undesignated.
