History
Hakiijō is said to have been built by Hakii Sanenaga in the early Kamakura period, but this is likely a conflation with the yakata (fortified manor hall) some distance south where Sanenaga is known to have lived. The Hakii traced their lineage to the Nanbu Clan, originally of the Seiwa-Genji of Kai, who relocated to Mutsu in the Muromachi period. In 1521, Fukushima Masanari, a vassal of the Imagawa Clan, invaded Kai Province from Suruga Province, and clashed with forces under Takeda Nobutora. The Takeda were victorious, and following the failed invasion, Hakii Yoshizane, who had supported the invasion, was attacked by Takeda forces at a place called 'Hakii no mine no shiro ("Castle of the peak of Hakii")', and it is thought that this refers to Hakiijō.
Field Notes
Hakiijō is a yamajiro (mountaintop castle) ruin in Hakii village in Minobu Township of historical Koma County. Ruins remain in the form of dorui (earthen ramparts), including a gate site, and a bailey. However, despite a large stele proclaiming the site and a profile for it on the town's website, much of the ruins are on private property, and guarded by dogs no less, so I could not see all of the remains.
