[Castle name]
Obama Castle (Awa)
a castle built by Yorisada Toki as a mean to support Mangi Castle

Awa Obama Castle was located in Ohara Isumi-shi, Chiba. Mino Official Katsusada Yarita, a loyal servant to Yorisada Toki, built and owned this castle on the cliff at Cape Hachiman.

The Toki clan at Mangi Castle used to serve for the Satomi clan, but they betrayed their old master and supported Hojo clan as Hojo clan increased their power in Sagami. On the other hand, Katsusada Yaritaminonokami’s loyalty to Satomi clan continued, and followed Yoshiyasu Satomi to invade Miura in Sagami, Hojo’s territory. While they were away, a former servant to Satomi clan, Yoritada Masaki conquered Obama Castle.

As Mino Official Yorita heard the news, he went back to Obama Castle right away and won it back. After the incident, Yoritada Masaki served for Satomi clan once again and continued to serve along with Masaki head clan at Otaki Castle.

Although Yoshiyasu Satomi supported Hideyoshi Toyotomi when attacking Hojo clan, Yoshiyasu’s land in Kazusa was taken away because he acted without following Hideyoshi’s order. Yorisada Toki at Mangi Castle was terminated since he worked for Ujimasa and Ujiteru Hojo.
