A Natural Fortress Protected by Rivers

Yoshida Castle in Toyohashi was built at the point where the Toyokawa River makes a wide bend and joins with its tributary, the Asakura River. These natural waterways served as moats, enhancing the castle’s defenses and making it a true natural stronghold. Standing on slightly elevated ground, the castle offers a view of the meandering Toyokawa, and with few tall buildings in the area, visitors can still imagine the scenery as it once appeared centuries ago.

Today, a reconstructed keep has been built, making the site a popular sightseeing spot. The remaining stone walls and moats allow visitors to stroll through the grounds while experiencing the atmosphere of the Sengoku period.

Although it is called “Yoshida Castle,” it stands in present-day Toyohashi City because the area was once known as “Yoshida.” Both the castle and its castle town shared the same name, giving visitors deeper insight into the historical connection between the place and the castle.
A Castle Linked to Renowned Generals

Several prominent warlords in Japanese history once ruled Yoshida Castle.
One was Sakai Tadatsugu, a loyal retainer of Tokugawa Ieyasu. He was counted among both the “Four Heavenly Kings of Tokugawa” and the “Sixteen Generals of Tokugawa.” His role as lord of Yoshida Castle highlights the strategic importance of the site.

Another notable figure was Ikeda Terumasa, later famous for his large-scale renovation of Himeji Castle. At Yoshida, Terumasa strengthened the castle’s defenses by building stone walls around the honmaru (main bailey) and expanding the grounds with secondary and tertiary enclosures and samurai residences. Had he governed the area longer, Yoshida Castle might have evolved into a grand early modern fortress on par with Himeji. In this sense, Yoshida can be seen as a “phantom great castle” that never reached its full potential.
Now Part of Toyohashi Park

Today, Yoshida Castle is located within Toyohashi Park, serving as a beloved relaxation spot for both locals and visitors. The spacious park can be enjoyed with a leisurely one-hour stroll and is especially famous for its cherry blossoms, attracting crowds of people for hanami (flower viewing) in spring.
The combination of stone walls, the reconstructed keep, and the seasonal beauty of nature makes it a place where history and scenery can be enjoyed together. Walking along the flow of the Toyokawa River, visitors can imagine the lives of people in the Sengoku period and spend a special moment immersed in both history and nature.
