Although the exact year of construction is unknown, there are written records stating that Takeda Castle was said to have been built around 1443. After conflict with neighboring states, Takeda Castle was often targeted by surrounding territories, and even 100 years after it was built, a lord who had established a large and powerful state tried to attack the castle many times in a quest to gain control of Ikuno Silver Mine. It was said that “he who has control over Ikuno has control over the country”, which showed the importance of Ikuno.In autumn when temperatures vary largely between day and night, the mist that rises from the Maruyama River causes a sea of clouds to form, and on some days, this sea of clouds covers the foot of the castle ruins, which stands atop a small mountain.

No buildings are left standing on the castle grounds, but the foundations are still largely intact, making it easy to see the castle's layout with a central fortress and three wings emanating from it. There are various locations around the grounds with great views of the surrounding mountains and the town below.
