冨津の小森中黒1558番地の川向こう 天津神社の南東の 標高約250m 高さ約120mの山で、小森東平893番地の北 北緯34度55分36秒・東経136度48分44秒付近が 「百坂城跡」(東西約250m×南北約100m)です。北側の麓は 豊岡川で 絶壁、東と西は 深い谷、南は 五明の山塊で弁蔵から 旭山へ続く谷を 見下しています。上加茂合戦 直前では 吉川元春軍が 美作から 加茂へ入る 道の守りです。即ち 小森から 江与美を通り 美作に向かう 交通の要所で、戦略的 に重要な位置を なしています。 毛利の将 菱川右京亮 菱川左京 菱川与四郎(小森城主の右京の長男) 菱川与九郎(右京の次男)或いは 松田氏傘下の菱川右京亮(三村家親に従い月田合戦に参加)が 城主とされます。「加茂川町の山城」菱川与兵衛は 与九郎の兄で 虎倉城主 伊賀配下の侍であり、百坂城の城主です。毛利の将 或いは 松田の将と 表現されている武将が 示されていますが、伊賀氏は 元々松田氏の家老職で、備中兵乱の頃は 毛利軍に 属していましたので いずれの武将も 伊賀氏の武将であったとしても そのように表現して 間違いではないでしょう。上加茂合戦時の城主は 恐らく菱川与四郎でしょう。 Ruins of Mozako-jyou/castle are located on the north of 893 Komori-Higasi-hira The north side is a precipitous cliff faced Toyooka-gawa/river, the east and the west side are deep gorges, the south side is a mass of mountains of Gomyou, and the valley where lead from Benzou to Asahi-yama can be overlooked It was the defense against Motoharu Kikkawa's army who may invade from Mimasaka to Simo-gamo That was traffic important position from Komori via Eyomi to Mimasaka, and was strategic important position It is said that the lords of the castle were Sakyou Hisikawa who is a general leader of Mouri clan, Yosirou Hisikawa who is first son of Ukyou Hisikawa “the lords of Komri-jyou/castle”, Yokurou Hisikawa “second son of Ukyou” and Ukyou-no-suke Hisikawa who was a direct retainer of Matuda clan and participated in the Tukida-gassen/war following Ietika Mimura Although general leader of Mouri clan and a direct retainer of Matuda clan are shown, even though they were military commanders of Iga clan , that may possibly all correct , because Iga clan was a chief retainer of Matuda clan originally, and belonged to Mouri clan at Bityuu-heiran/war The lord of the castle was probably Yosirou Hisikawa
この頂上が 百坂城の主郭です。元の分岐に戻り、左の分岐を進むと 頂上を囲むように 上段 下段に 平坦地が幾つも有ります。その一つは 石垣が組まれ、かつて民家が 建っていたそうです。これ等の平坦地は 城地跡の平坦地を活用して 耕作されていたものと 推測します。その内の 竹藪になっている平坦地の1つには 1.5m程の井戸 或いは 池の跡と思われる穴が 開いています。北東に 進むにつれて 植林地となり、頂上のほぼ北側に来ると 墓のある先に 平坦地があります。北方に天津神社が建っています。
