Koizumi Castle History Exhibition
Construction background and construction by Tomiji clan
Koizumi Castle was built in 1489 by Yutomi Kaikinosuke Naomitsu. The 11th descendant of Tomomitsu Tomomitsu was Yukihisa Tomomitsu. The surname of Tomi was originally used in other places, which is due to the fact that his father was born in Tomi, village of Tomi, in Amano District, Ueno Province.
After his death in the middle of the war, another child, Mitsu, fled to this place, and changed his name to Tomika Rikinosuke Naomitsu. In this case, there are many kinds of dialects established by the Fuji clan. There is no doubt about it, it is possible to be positive, and in the late Muromachi period, when the Fukui clan was founded, there was a lot of new excitement in the area.
Kōkō Shogun Yotomi Clan’s series
At the time of the construction of Koizumi Castle, Mr. Shigeshi Ashikaga, the commander of the armored military, was in charge of the effectiveness of Tomitsu Naoko. At that time, during the conflict between the Eastern District Zhengzhuang Province General Army and the Yamanouchi Uesugi clan (Guan Eastern Official Rei), the Tofuji clan was included. The military’s military performance was one-sided, and Naomitsu fought against the Yamanouchi and Uesugi clans.
Koizumi Castle was built on a low-lying wetland along the Tone River water system, with an excellent geographical location, and with clever land use and surrounding natural topography. The geographical location of the Futian clan and its governing status are very important.
Yo Uesugi Shinnobu’s system and power change
During the 16th century, Uesugi Masatora (later changed his name to Uesugi Noshin) of Ekkou Province began to invade the eastern part of the country. Under the great military power of the people in the East, who were subject to much force, the Fujo clan was also an exception.
During the restoration of the Uesugi clan, the Tomitsu clan was appointed, and the ceremony began. During this period, the Tofu clan was active in the political bureau in the eastern part of the country, and the Uesugi clan, the Hojo clan, and others were very active.
Yohojo clan’s lineage and activities during the war period
As a result of the war, the eastern region of the Hojo clan in Sagami Province continued to push forward continuously. A record of literature from the time when the Tomi clan and the Hojo clan were established, and the country was still under control. In his works such as “Collection of Historical Materials of Thousand Leaves” and other books, he recorded various exchanges between the Tokugawa clan and the Hojo clan.
The Tomi clan was a powerful local owner, and the Soyo Yura clan had many exchanges. During the battle for power in the eastern part of Ueno Province (currently the current group of horses), the construction of Koizumi Castle played an important role in the success of the Tofu clan’s position.
The fall of Koizumi Castle in 1590
The history of Koizumi Castle ended in 1590. When Hideyoshi, his vassal, attacked Odawara, the Tomi clan was elected and the Hojo clan formed an alliance. However, this was the final decision of the Tomi clan.
When Hideyoshi, his vassal, invaded the eastern region, Joya Koizumi completed the attack. There was a huge difference in military performance, the fall of Koizumi Castle, and the death of the Tomitsu clan. After the Hojo clan was destroyed during the Battle of Odawara, the Tomi clan disappeared on stage during the battle, and Shinya Koizumi Castle was killed.
The construction of Koizumi Castle was the residence of the Tomiji clan for about 100 years, and the end of the war was over.

Main hospital building and Hijikata engineering structure
The core of Koizumi Castle: the construction of the main castle tower (honmaru). This little Hijikata process has been perfectly preserved, so please understand that it will be a treasure of the castle’s history at this time.
The Hijikata process of the main temple’s temple is several meters high, and the temple is built on the top of the temple. The land within the Hijikata project is flat, the residence of the owner and other important constructions are evenly distributed. This is a small piece of earthworks, and the construction of the earthworks has been preserved for over 500 years.
Water supply system
The defense of Koizumi Castle is located in the castle’s main castle. Inner castle river completely built castle, with permanent water storage. This little water source comes from a self-circulating wetland and drains, which has now become a state-of-the-art water use technology.
Outside the castle river, inside the river. However, there is still a part of the castle outside the castle, but the castle has a well-organized exterior. However, the city river does not have any defensive functions, it is a water source that provides daily life within the fort, and it is a rapid water source.
Cloth Bureau
Koizumi Castle Arita Field (kuruwa). The fortress is a functionally flat area within the fort. At the same time, the castle tower is placed in a concentric circle, and the second and third towers are located at the center.
Each road was divided into two parts: the construction of the city, the river separation, and the formation of a multi-level defense system. Immediate attack by the enemy, one way to defend, and the ability to provide effective defense. In summary, Koizumi Castle is a typical castle fort construction technique during a military expedition.
Jyomenwa Entrance
The position of Koizumi Castle is the castle gate, but the exact position or structure of the castle is shown in front of the gate. However, due to the construction of the earthworks and the exit of the castle river, we were able to determine the location of the main entrance.
The main gate (main gate) is located on the south side of the castle fortress, and is the main dry road of the castle town leading to Miangyang. In addition, there are other castle gates, such as the following gates (Karate gate) and water gates (Water gates), which are also possible, such as the route for transporting crops for peacetime periods in peacetime, and the route for transporting crops during emergency situations in China.
