It's unknown when the castle was established but it was likely built by the Ohmuro clan who were long time local lords. After the fall of the Takeda in 1582, the Ohmuro briefly switched allegiance to Nobunaga's ally Mori Nagayoshi. When Nobunaga died shortly afterwards the Ohmuro allied with Uesugi Kagekatsu. The castle was likely abandoned when the Ohmuro moved to Aizu with Uesugi Kagekatsu in 1598.

Visit Notes

The castle is on the end of a ridge overlooking the plain where the Battles of Kawanakajima took place. It is a steep but short 10 minute climb to the top and well worth the visit. You don't find this extensive mountaintop stonework in such an accessible location elsewhere.

Kasumijō / Hanishina-Kajō / Ômurajō (Matsushiro)  霞城 ・埴科霞城・大室城[松代]

The ruins of Kasumi Castle are some of the most impressive I've seen at a Sengoku Period Yamajiro (mountaintop castle). The ishigaki (stone-piled ramparts) remains are extensive and located all over the castle mount, starting almost immediately from the south trail. The ramparts here are more impressive than around the main bailey. To the northeast-ish side of the main bailey there are lower walls which zig-zag up the mountainside. A minor bailey here runs to the southeast but much of this side of the mountain seems to have succumbed to landslides, taking thousands of stone blocks with it. The terrain here is difficult and near impassible due to all of the loose blocks. Some segments of ishigaki seem only held in place by the tangled growth of creeping vines and tree roots. The lower reaches of the castle to the south are less maintained, and I'd like to see some trees felled here before their roots unlodge more walls. The top of the castle is better maintained and there are some information boards.
