This is all about Kasama Castle Ruins you want to know.
Every information you get on this site will be from a credible source based on Japanese history (books for reference).

"Kojō ezu(picture in Edo Period)" from 国立国会図書館

Collected by the Inagaki family, the Toba Daimyō from the mid-Edo period to the Meiji Restoration, as materials for military studies. There are about 350 illustrations, but there is no uniformity because only illustrations of castles, illustrations including castle towns, and old battlefield illustrations are mixed.
Another typical example of a castle picture in the Edo period is "The Shōhō Shiroezu", picture of the castle and castle town that the Edo Shogunate ordered the daimyō to create and submit,aggregating military information such as the buildings inside the castle, the height of the stone wall, the width of the moat and the water depth, etc., it also details the location and shape of the castle town and the mountain river.

Ruins of Honmaru

Kasama region became the territory of Gamō Hideyuki, a child of Gamō Ujisato in 1598. He assigned Gamō Satonari, a chief vassal, as a substitute for the castle owner. Kasama Castle was renovated from a medieval castle to a modern castle by Satonari. A huge earthworks still exists on the south side of the square where the palace was once set up, and double structure turret, called "Hachimandai Yagura", was built on the upper part of it. this yagura was relocated to Shinjōji-Temple in 1880 and now still used as a temple hall.
Stone wall around Honmaru
There was a Kuruwa with main keep at the top of the mountain, which is a stone staircase further up from Honmaru. It was unusual for a mountain castle that main keep was to be built. However, it was not a huge one as generally imagined, but a scale and a simple thing about a double structure turret. A huge stone wall that stretches for about 4 meters under the main keep is spectacular. Unfortunately, it was destroyed by East Japan Earthquake in 2011, and it seems that it will take some time to completely restore it. Currently, the Sashinō Shrine is enshrined there.
Ruins of Ōtemon Gate

At the Ōtemon Gate ruins, the eye-catching is the stone wall behind it. This was built in 1598 when Gamo Satonari was renovating Kasama Castle to a modern castle, and there are few castles using stone walls in Eastern Japan region.
Ruins of residence of castle lord

Kasama Castle was also a residence of the lord of Kasama Clan throughout Edo period, and it is also a very unique example of the Meiji Restoration as a mountaintop style castle.
