History of Oshima Castle
From the end of the Heian period to the Long-established period: Construction by the Oshima clan
The exact construction date of Oshima Castle is still uncertain, but it is universally acknowledged that the area was constructed by the Oshima clan, and the clan was directly restored during the Heian period. The origin of the Oshima clan may have been traced back to the 8th son of the lord of Funayama Castle, Yoshiyuki Katagiri, Hachiro Munen, and others were descendants of the Ina-Genji clan. After part of the land in the Dashima area, the name was changed to Dashima.
At that time, Oshima-cho (Konfuru-cho Waraii district) was a strong local family, the Oshima clan, the use of the Tenryu River’s steep topography, the construction of a mountain castle, and other urgent circumstances. The Oshima clan was established in Oshima town, and the fort was located in the Japanese castle town.
The Age of War: Takeda Shingen’s Great Relief
In the 23rd year of the Tenbun period (1554), Kai Province’s general, Takeda Shingen, invaded Ina District, and the Oshima clan took control of Oshima Castle. The Takeda clan’s land invasions, the construction of Daishima Castle, its important strategic strategic point, the invasion of Iwakuni and its base in Jiangjiang Province, and its defense base in the Ina region.
In 1571, Takeda Shingen, the lord of Tadashi Castle, Akiyama Torashige (Nobutomo), made a large-scale imitation of the castle. This time, the envoy visited Daishima Castle, Yotaka East Castle, and two large fortresses in the Ina area of the Takeda clan. Takeda Harunobu (Shingen) August 18, 2015 (unverified); confirmed that Toramitsu and other people living in Japanese-style rooms in Akiyama Zen’s gate were present in the castle.
This time, the construction of Dashima Castle was completed, and the fortress was completed with great technical skill. Takeda-style defense system, including a double moon fang-shaped castle, Kawa large-scale outer fort, and one of the most solid forts in the Shimoina area. ### Tensho 10th year (1582): Invasion of the Kita Army and fall of Ina Castle
1582, Nobunaga Ida’s chief son, Nobutada Ada, entered the Ina area. After the fall of Yantian Castle, the Takeda army gathered forces and returned to Daidai Castle, trying to resist. However, Shingen Takeda’s younger brother, Nobuaki Takeda, who was the commander of the castle, was forced to flee the castle.
The defenders also set fire to the castle and fled, and the castle quickly fell. This incident was one of the most notable events during the rise and fall of the Takeda clan. Oshima Castle had solid defensive construction, but in the end, the castle owners rebelled and failed.

Dashima City’s most notable subject is Yucheng Gate’s Two Moon Fang Shape 护城川和圆形哮城. After the car stopped, the circle-shaped castle was shaken by the engraving. As you can see, this is the most representative example of the construction style of Koshu Castle Fortress.
The structure of the city is divided into two layers, the shape of a new moon, and the effective invasion of the enemy. The entire structure is perfectly preserved and clearly visible. There are still people living in the city, and some areas still have traces of life in the past.
Main castle, two castles and three castles
From the center of the fortress to the farthest main castle, it consists of two castles and three castles. As the height and fall of each castle fell, he dug deep into this space and the river of the city dried up. This is a little dry and dry, so the castle river doesn’t come up with a defensive effect, so Hijikata can provide Hijikata with the process.
The surrounding area of the main city is clear and you can see the traces of earthworks, and you can see the ancient history of Dashima Castle. In addition, each time the city is surrounded by a pond and a distant view of Amani Bisi Mountain, China’s Amani Bisi Mountain, the magnificent scenery is also the biggest highlight of the city. ### Hijikata Construction Bureau

The construction of the earthworks was completed in various places within the castle, and the defensive lines were formed. This is the construction technique of “Yokoyagari” (side wing defense) used for the construction of the earth, which is the characteristic of Koshu castle fort construction, and the exquisite strategy of the side wing attacking enemy has been developed.

During the journey, a huge dry city river trembled between the two forts and the main fort. As the river dried up, the water depth of the city increased, and the fortification construction technology was developed at a very high level. As the bottom of the castle river has improved, Hijikata’s engineering work has increased the depth of the river, and the depth of the river has increased, attracting people’s attention.
