Dewa fence - Dewa fence

Japanese: 出羽柵 - でわのさく

An ancient fortress that is said to have been built near the downstream of the Mogami River in the Shonai region of Yamagata Prefecture. Its first appearance in literature was in the entry for July 1, 709 (Wado 2) in the Shoku Nihongi, an imperially appointed historical text compiled in the early Heian period. Since Dewa County was established in Echigo Province in 708 (Wado 1), it is thought that this fortress was built when Dewa County was established. However, its location has not been identified. According to Shoku Nihongi, Dewa Castle was moved to the area of present-day Akita City in 733 (Tenpyo 5) as the sphere of influence of the Yamato government moved northward, and this became Akita Castle. A provincial government office was established in Akita Castle, but due to successive Emishi rebellions, the provincial government office was moved back to the Shonai region. The most likely location for this site is Kinowa Castle in Sakata City, Yamagata Prefecture. ◇It is also called "Dewanoki" or "Ide- no -ki."

山形県庄内地方の最上川下流付近に設置されたとされる古代の城柵。平安時代初めに編纂された勅選史書『続日本紀(しょくにほんぎ)』の709年（和銅2）7月1日の条が文献上の初出。708年（和銅1）に越後国に出羽郡が設けられていることから、出羽郡設置とともに設けられた城柵とも考えられる。ただし、所在地は特定できていない。『続日本紀』によれば、出羽柵は大和政権の勢力圏が北上するにしたがい、733年（天平5）に現在の秋田市付近に移設され、これが秋田城になった。秋田城には国府が置かれたが、蝦夷の反乱が相次ぎ、国府は再び庄内地方に移転した。その有力な候補地とされているのが同県酒田市にあった城輪柵(きのわのさく)である。◇「でわのき」「いではのき」ともいう。
