History

It is said that Tanba-Tonborijō was erected as an early satellite fortification of Kuroijō by Akamatsu Sadanori. This is uncertain. However, the site was later the fortified residence of Ogino Iyomori in the Sengoku Period. In 1554, Ogino Iyomori was killed at Tonborijō by Ogino Naomasa (also called Akai Naomasa) who then became lord of Kuroi Castle. It may be that Tonborijō was abandoned at this time. Tonborijō was built on the eastern edge of a hill in the plain, with a trench cut in the west to protect its flank. It is thought that the castle possessed a yagura (turret).

Field Notes

The ruins of Tonborijō, which consist of some earthworks and augmented natural terrain, is now dominated by a complex of modern structures, including an Italian restaurant, overlooking the surrounding countryside. There is a large stone marker proclaiming the site, and I spied some dorui (earthen ramparts) and what looked like a karabori - though not advisable to descend. The road cuts through the dorui. The shape of the terrain has been altered in modern times, obscuring the castle's footprint.
