Norisada Kobata Castle




Kobatajō was constructed by Matsudaira Nuidononosuke. Little is known of this figure, but he is supposed to have been related to the Ogyū-Matsudaira.

Visit Notes

Kobatajō is a yamajiro (mountaintop castle) ruin in Norisada Township, Toyota Municipality. The castle is located on a hill wedged between the confluence of two rivers, the Tomoe River and its tributary. A bridge spans the smaller river, which allows for easy access. A forest road continues above the bank of the Tomoe but there is a trail to the castle striking up the ridge a little way along.

Kobatajō has three integral baileys. All are fairly spacious, now hosting a cedar plantation, but the second bailey, separated from the third by a small terrace of the ridge, is busy with large boulders. The main bailey is esconced by dorui (earthen ramparts). The dorui seems to have been heaped up at least partially from within the bailey itself. This style of parapet wall is not seen at other castles in the area.

To the rear of the site the dorui is broad and flat, not unlike a turret emplacement. Below here to protect the ridgeward rear of the site is a horikiri (a trench which bisects the ridge).

Note: this site is called Norisada-Kobatajō to distinguish it from with other similarly named sites nearby.
