The colors of Takeda Army from BUSHOO！JAPAN

The Takeda army led by Takeda Shingen, said to be the strongest in the Warring States period. It is said that the character "風林火山" written on the flag of the headquarter was used from the ancient Chinese "Sonshii" martial arts book. There is also anecdotal evidence that the enemy lost their willingness to fight just by looking at this flag. ( from Kōfu City HP )

The person who built this castle was Takeda Nobutora ,the father of Takeda Shingen. Nobutora surrendered Mr. ōi, who had a great influence in Kai district, and decided to move base to Tsutsujigasaki in 1519. The following year, Nobutora built a mountaintop style castle on a Mt.Yōgai in the north of Tsutsujigasaki. It is said that this was a castle construction under the assumption that during normal times, the palace was appointed to the government, and during the war, it was supposed to stay in the defensive castle. For the Sengoku Daimyō, the last defense castle is "Tsume-shiro". For the Takeda family, this castle was exactly what was called.
The monument of the birth place of Takeda Shingen

The year after the construction of this castle, the commander of the Imagawa family, Masanari Fukushima, led a large army and invaded Kai district as expected by Nobutora. During this battle, Nobutora's wife was having a baby. Therefore, the wife evacuated to Yōgaiyama Castle. Takeda Shingen was born at this time.
The main part, which is surrounded by earthworks on all four sides, is a slender "Kuruwa" that measures approximately 70m east-west and 20m north-south. Enemy must break through the 1st to 8th gates before reaching the main part. The gate was also equipped with advanced defense measures to prevent the invasion of the enemy.
Takeda Clan grew power from the land of Kai as a representative daimyō of East Japan that can aim to unify the world at that time and made it famous all over the country, the driving force was very good castle construction. Even in posterity, it is famous as "Takeda school construction technology". A characteristic of the Takeda family's construction of castles is that they choose locations with cliffs and rivers on the back and sides and limit the battle direction to the front. Then, the enemy was limited to the front, and "Maru-Umadashi", which semi-circular earthwork at a defense facility to be installed before entering and leaving was built to reinforce the entrance of Kuruwa. Also they defeated an enemy crawling up the mountain by building "Tate-bori", a trench sawed vertically against the mountain slope.
This is a must-see for those who want to feel the atmosphere of history that the Takeda family has been making a castle for three generations. 【Please note that the area is a bear infestation area, except in winter】
