During the Ashikaga Shogunate Obamajō was built and controlled by the Ishibash-shi (clan), as part of Shiomatsu-han (Shiomatsu Fiefdom). In 1568, Ōuchi Yoshitsuna usurped Ishibashi Naoyoshi and took over the fiefdom. In 1584, the Ōuchi, under Ōuchi Sadatsuna, allied with Date Masamune, but the next year forsook him and joined with the Ashina-shi. This was to be their undoing. Masamune conquered the fiefdom. In 1586, Obamajō was taken without a battle because Ōuchi Sadatsuna fled to Ashina-controlled territory. At the same time Date Terumune, Masamune’s father, entered Miyamorijō, where he was then abducted by the Daimyō Hatakeyama Yoshitsugu and killed in the ensuing battle when Masamune tried to rescue him. In 1591, Gamō Ujisato, ruler of Aizuwakamatsu, took over Shiomatsu-han and installed his retainer, Gamō Chūzaemon, at Obamajō. It was under the Gamō that the stonewall which remains today was constructed. Obamajō was abandoned in 1627 after its castellan was transferred to Iyo-Matsuyamajō.
I rented a bike from Nihonmatsu station and cycled to Obama village, which took about 40 minutes. Name "Mutsu-Obama" used to distinguish it from a castle of the same name in Obama municipality. Profile and photos contributed by AdamT.
