Background

Kasugayama Castle extended over two ridges on the summit of 180-meter Mount Kasuga. The castle had no stone walls but consisted of many enclosures ('' kuruwa'') with earthen or clay ramparts and dry moats built on terraces at various levels on the mountain. The core of the castle (or inner bailey) was just below the peak, and contained a watch tower, Buddhist temple (and Uesugi Kenshin's residence) and garden. On the south ridge was the fortified residence of Uesugi Kagekatsu, the adopted son of Kenshin, below which was the residence of Kakizaki Kageie, one of Kenshin's most important retainers. On the north ridge was the residence of Naoe Kagetsuna, another important retainer. Immediately below the central area was the residence of Uesugi Kagetora, another adopted son of Kenshin. In addition to these major enclosures were many smaller enclosures for retainers and barracks for soldiers, as well as warehouses. The castle is the centre of a defensive network consisting of many smaller forts in a two to six km, radius.
