Kasugayama-jou (春日山城)

Also known as: Hachigamine-jou

Kasugayama Castle was Uesugi Kenshin's primary fortress, located in present-day Niigata Prefecture. It was built by the Nagao clan, and Kenshin became its lord in 1548 (some say Kenshin built the castle). Uesugi Kagekatsu won control of the castle in the Otate no Ran after his adopted father's death.
