Visit Notes

Nagaijō is a fortified residence site in Fukuoka Township, Okazaki Municipality, situated at the convergence of the Kōta and Urabe rivers. The site is now fields and no ruins remain, but a small stone marker stele and wooden info' post have been erected for the site. Nagaijō is connected to the Yamamoto Clan, and there is also a small cenotaph to Yamamoto Kansuke, the famous Takeda general, on the otherside of the road from the marker posts, though Yamamoto Kansuke's exact relationship to this site is unknown.
