Kasugayama Castle Ruins — the historical setting

Kasugayama began as the fallback castle of the Uesugi shugo of Echigo, then served four generations of the Nagao and Uesugi, including Uesugi Kenshin and Kagekatsu, famed for natural defences, complex baileys and dry moats; it was abandoned in 1607 when the Hori moved to a new Fukushima Castle near Naoetsu.
