Noshiro Plain - Noshirohei

A plain developed downstream of the Yoneshiro River in northwestern Akita Prefecture. The Noshiro Sand Dunes stretch along the Sea of ​​Japan, with the northern dunes being vertical dunes parallel to the coast, while the southern dunes tend to be horizontal. Inside the coastal dunes are widespread alluvial plains and uplifted deltas. Black pines have been planted on the dunes as erosion control forests since the Akita Domain era, and the inside of the dunes are used for farmland and orchards, where onions, potatoes, eggplants, and pears are grown. After World War II, large-scale settlements were carried out on the uplifted delta, and Shinonomehara on the right bank of the Yoneshiro River in particular was developed and turned into rice paddies. The Noshiro Plain's settlements take the form of towns and villages behind the sand dunes, below the eroded cliffs of the uplifted delta, and on the natural levees, with many settlements called Shinden and Hatachi (a word meaning newly reclaimed land). The urban area of ​​Noshiro, which forms the center of the plain, has developed on the sand dunes on the left bank of the Yoneshiro River.

秋田県北西部、米代川(よねしろがわ)の下流に発達した平野。日本海沿いには能代砂丘が連なり、北部の砂丘は海岸に並行した縦砂丘であるが、南部は横砂丘の傾向がある。海岸砂丘の内側には沖積平野と隆起三角州が広く展開している。砂丘には秋田藩政期から砂防林としての黒松が植林され、砂丘の内側は畑地や果樹園に利用され、ネギ、ジャガイモ、ナス、ナシが栽培される。隆起三角州面は第二次世界大戦後に大規模な入植が行われ、とくに米代川右岸の東雲原(しののめはら)は開拓され水田化した。能代平野の集落は砂丘裏、隆起三角州の侵食崖下(がいか)、自然堤防上に街村形態をとり、新田、羽立(はたち)（新開地を意味する語）という集落が多い。平野の中心をなす能代市の市街地は米代川左岸の砂丘上に発達している。
