History of Toyoda Castle and the Genealogy of the Toyoda Clan
Origins of the Toyoda Clan and Their Relationship with Taira no Masakado
The Toyoda clan, who built Toyoda Castle, were a branch of the Kanmu Taira clan, and their ancestors can be traced back to Taira no Shigemori, a military commander of the Heian period. Taira no Shigemori is known for his achievements in suppressing Taira no Masakado, who shook the Kanto region during the Jōhei-Tengyō Rebellion (935-940).
The Toyoda clan is said to have originated when Taira no Masamoto, who distinguished himself in the Former Nine Years’ War (1051-1062), received territory in Toyoda District, Shimōsa Province (present-day Hon-Toyoda area, Jōsō City, Ibaraki Prefecture), and adopted the name Toyoda. The Toyoda clan built a castle in this area and ruled the region for approximately 400 years, from the late Heian period to the Sengoku period.
Location and Significance of Toyoda Castle’s Construction
Toyoda Castle was built on the banks of the Kokai River, which flows through the eastern part of the region. The Kokai River is an important river in the Tone River system, occupying a crucial position from the perspectives of water transport and military defense. Utilizing the river as a natural moat and its location overlooking the plains, it exhibits typical characteristics of a medieval flatland castle.
At that time, Toyoda Castle functioned as the political, economic, and cultural center of the Ishige region, and the Toyoda clan’s influence extended over a wide area centered around present-day Joso City.
The Toyoda Clan in the Sengoku Period and its Downfall
During the Sengoku period (Warring States period), the Toyoda clan maintained its power by building relationships with powerful surrounding daimyo. In particular, they strengthened their ties with the Oda clan (Hitachi Oda Castle) to counter the pressure from the Tagaya clan (Shimotsuma Castle) advancing southward from the north.
However, at the end of the Sengoku period, a tragedy occurred when the head of the Toyoda clan was assassinated in a rebellion by a vassal who secretly sided with the Tagaya clan. This incident led to the extinction of the Toyoda clan, and Toyoda Castle disappeared from the historical stage.
Afterward, this region came under the control of the Tagaya clan, and during the Edo period, it was governed as a direct territory of the shogunate and as a territory of hatamoto (direct retainers of the shogun).

Construction History and Purpose of the Facility
In 1992, Joso City (then Ishige Town, Yuki District) opened the Joso City Community Exchange Center with the aim of passing on the region’s history to future generations and serving as a base for resident interaction and cultural activities.
The facility’s exterior design, modeled after a castle tower, reflects the historical background of this region, which was once ruled by the Toyoda clan. Its beautiful exterior, with white walls and black tiles, is recognizable as “Toyoda Castle” even from afar, making it a landmark of Joso City.

Architectural Features of the Castle Tower

Standing approximately 30 meters tall, and situated on a plain with few tall buildings nearby, it can be seen from afar. Especially at night, it is sometimes illuminated, creating a fantastical atmosphere.
