Oshi castle appeared in “Nobouno Castle” that became a topic in the movie a few years ago.
It is a castle that has made his name familiar to the world under the opponent of Toyotomi Hideyoshi’s Kansai region army, even if main castle Odawara castle was still fighting, still continuing the battle against surrender.

While Toyotomi Hideyoshu surrounded Odawara Castle, it was Mitsunari Ishida of Hideyoshi’s aide who was ordered to attack this castle. Mitsunari was despised as a bad captain from Kiyomasa Kato and Masanori Fukushima.

Hideyoshi dared to order castle as supreme commander in order to make Mitsunari military exploits in this war.

However, the crucial Oshi castle was a natural haven surrounded by paddy fields and muddy fields.
There are no obstacles, but soldiers are hard to fall off from the castle because of not having any obstacles so they could see clearly.
Here, Mitsunari will imitate the massive floodwater that Hideyoshi had done at Bicchuu Takamatsu Castle before.

However, even though enormous breakwaters have been completed and the shipwrecks are immersed in water, it seems that the ruffled work that was built up by an overseer or originally instantly became a cornerstone, but fragile breakwaters are partly broken down.

A large amount of water flowed into itself in the Minari Army and many casualties occurred.
Odawara castle which is the main castle surrenders, and Oshi castle will leave its name as a castle which has continued to bask in the Odawara battle only to the last battle.

By the way, the castle owner of the castle at the time was Narita, that Uesugi Kensin also set up an attack twice, but he could not drop it again, raising it just by burning the castle.

It was a castle that faced Lake Suwa, and it was Mizuki that protruded to the lake side before the Edo period. However, due to the development of tidal flats in the early Edo period, it was a little away from the lakeside. Another name is called “Suwa’s float castle” etc.

Although it was originally a residence of Suwa, when Tokugawa Ieyasu handed over the Kanto, Suwa was leaving Takashima and it was transferred to the country of Musashi. After that, Hineno came in on behalf of Suwa, but in 1601 Hineno was transferred to Mibu, and Suwa returned to this place again.

It seems that it was unnatural when I returned to my ancestral land. Then, Mr. Suwa entered Takashima Castle, and it will be greeting the Meiji Restoration. In addition, Suwa retained the land in the Edo Era, Tokugawa Ieyasu’s sixth son “Tadakita Matsudaira” was entrusted with him to keeping the “Yoshiharu Yoshiharu (grandchild of Kira Uenosuke)” in some cases.

The current castle tower is restored and it also serves as a museum, and Inner citadel is being maintained as Suwa Park. I also tried climbing up to the castle tower, but it was certainly located somewhere away from the shore of the lake. Before the tideland development, it was reminiscent of castle tower that the figure reflected on the waterside was beautiful indeed.

After that, Koga Kubou Ashikaga continues for about 130 years to Ashikaga, Masauji, Takamoto Hare and Yoshiuji. “Furukawa Castle” is the castle that Koga Koga has been working as a base for generations.

This Furukawa castle was the center of the medieval Kanto. When entering the Sengoku Era, Koga Kubouke family will be swallowed as well as Hojyo’s advancing to Kanto.

And the daughter of Hojo Ujitsuna was married to Furukawa Kubou, which further strengthened the dominance of the Hojyo family. After that, the Koga Kubou family fought over and over in the uproar of the Kanto region, but when the Houjou Ujiyasu’s nephew “Ashikaga Yoshiuji” dies, there is no succession, and Koge Kubou will be discontinued here.

Originally Koga castle was built along the Watarase River, but unfortunately it was torn down without a trace because of the renovation work of the river. However, a monument called Kogaro inner citadel ruins is left on the bank of the river. Because there is not a chance to see it easily, it may be interesting to look around for a walk the Watarase River.

Ueda castle which Masayuki Sanada built was once destroyed after the battle of Sekigahara in Keichou 5th Year (1600 years), and is being restored by Sanada’s next castle owner Sengoku. This reconstruction work was the one that excavated the burial maot of Ueda castle of Sanada again.

Therefore, it can be seen that the basic plan of reconstruction Ueda castle (territory) is almost the same as when Masayuki Sanada’s foundation was founded. Well, that Ueda castle is located on the terraced cliff where the Chikuma river rises. Both Inner citadel and Outer citadel surrounding it are behind the cliffs and the Chikuma River. Also, Ohbori from Oter citadel North to the west, which was called a hundred drilling, was originally a natural river channel, which was expanded and divided by banks into a large water moat.

And the river which flowed here moved to the north, it bent at right angle in the northwest of the castle and dropped to the Chikuma river. On the eastern side of Outer citadel, outermost region of castle was arranged. This is the major direction of Ueda Castle, but it was divided by a moat in the north and south.

Nobuyuki (Nobuyuki), who succeeded the trace of Masayuki, expanded the town outside this major moat, but Ueda castle in the Masayuki Era had a range surrounded by this moat and Yadesawa river to outermost enclosure of a castle. It is thought that it was a structure that totally took in the castle town inside.

[Fighting the Tokugawa army twice, the hardcore boasting the iron wall defense system]

In the first battle with the Tokugawa Army in Tensho 13th year (1585), (First Ueda battle), it seems that it was the time to see whether it was completed for the first time, it was only the minimum stance.

However, by the battle of the Keioi 5th Year (the Second Ueda Battle), it was in a form that was maintained as a modern castle, such as arranging a tower at the main points.

It can be implored not only from various situations but also from the excavation situation of gold leaf tiles. Ueda castle is considered to have taken a more solid defense posture by Sanada than Ueda castle after Sengoku reconstruction, even from the uncovered points and others places.

Masayuki Sanada attacked the army of the Tokugawa army twice and rejected it, based on this castle.
