Matsue Plain - Matsue Heiya

A plain in the eastern part of Shimane Prefecture. It is an alluvial plain created by the Ohashi River, which connects Lake Shinji and Lake Nakaumi, part of the Shinji lowlands. It is sandwiched between the Shimane Peninsula to the north and the hills in front of the Chugoku Mountains to the south, and is long and narrow from east to west (about 10 kilometers). The hills of Mount Dake, Mount Wakura, Mount Akayama, and Mount Agenogi stand out. It is thought to be part of the "Umi no Umi" in the "Izumo no Kuni Fudoki." In the early modern period, after the construction of the castle town of the Matsue Domain, land reclamation and reclamation progressed, and the city of Matsue developed on both sides of the Ohashi River. The straight roads in the city were once waterways in the marshland. In addition to using the plain for rice paddies, Tsuda turnips are cultivated in Asakumi, and Japanese parsley is cultivated in Kuroda.

島根県東部にある平野。宍道(しんじ)低地帯の一部で、宍道湖と中海(なかうみ)を結ぶ大橋川がつくる沖積平野。北の島根半島と南の中国山地前面の丘陵に挟まれ、東西に細長い（約10キロメートル）。嵩山(だけさん)、和久羅(わくら)山、赤山、上乃木(あげのぎ)の諸丘陵が突出する。『出雲国風土記(いずものくにふどき)』の「意宇(いう)の海」の一部とみられる。近世、松江藩の城下町建設後に埋立てや干拓が進み、大橋川の両岸に松江の市街地が発達した。市街の直線道路はかつての湿地の水路である。平野は水田利用のほか、朝酌(あさくみ)で津田カブ、黒田でセリの栽培が盛ん。
