Omagari - Oomagari

The former name of a city located in the central part of Akita Prefecture. It currently occupies the central-southern part of Daisen City, and is located in the northern part of the Yokote Basin. The former Omagari City was established in 1954 (Showa 29) when Omagari Town and the five villages of Hanadate, Okawanishine, Uchiotomo, Yotsuya, and Fujiki merged. In 1955, Kakumagawa Town was incorporated. In 2005 (Heisei 17), the six towns of Kamioka, Nishisenboku, Nakasen, Kyowa, Senboku, and Ota, as well as Nangai Village, merged to form Daisen City. The name Omagari is taken from the name of a medieval village. The JR Ou Main Line and National Route 13 run north and south through the center of the region, and it is also the starting point of the Tazawako Line, and National Route 105 also passes through the area. In 1997, the Akita Shinkansen Line, using the Tazawako Line and the Ou Main Line, was opened, and in 1991 the Akita Expressway was opened and the Omagari Interchange was established. During the Edo period, the area was under the control of the Satake clan and was located along the Ushu Kaido road. The head inn was located in Omagari, the center of the area, and a station was also established in Takazeki Shimogo. It is the confluence of the Omono River and the Tama River, and until the Ou Main Line was opened, the Kakumagawa River was a key port for shipping and prospered as a place for shipping rice from the Senboku region. It is one of the prefecture's leading rice-producing areas and is also the commercial center of Senboku. The main hall of Koshio Shrine was built by Hida craftsmen in 1570 (Genki 1) and is designated as an Important Cultural Property by the national government. In August, the shrine holds a national fireworks festival.

秋田県中央部にあった旧市名。現在は大仙(だいせん)市の中南部を占める地域で、横手盆地北部に位置する。旧大曲市は、1954年（昭和29）大曲町と花館(はなだて)、大川西根(おおかわにしね)、内小友(うちおとも)、四ツ屋(よつや)、藤木の5村が合併して市制施行。1955年角間川(かくまがわ)町を編入。2005年（平成17）神岡、西仙北、中仙、協和、仙北、太田の6町および南外村(なんがいむら)と合併して大仙市となった。大曲の名は中世の郷村名をとっている。JR奥羽本線と国道13号が地域の中心を南北に走り、また田沢湖線の起点であり、国道105号も通じる。1997年田沢湖線、奥羽本線を利用した秋田新幹線が開業、1991年には秋田自動車道が開通し、大曲インターチェンジが設置された。江戸時代は佐竹氏秋田藩領で羽州街道に沿い、中心の大曲には本陣が置かれ、高関下郷(たかぜきしもごう)にも駅場が設けられた。雄物(おもの)川と玉川の合流点であり、奥羽本線が開通するまで角間川は舟運の要津として、仙北地方の米の積出しなどで栄えた。県でも有数の米どころであり、また仙北の商業の中心でもある。古四王神社本殿(こしおうじんじゃほんでん)は1570年（元亀1）飛騨匠(ひだのたくみ)の手になり、国の重要文化財に指定されている。8月には全国花火大会がある。
