Niigata

Niigata is located in the central part of the Sea of Japan side of Honshu, and agriculture is practiced mainly in the Echigo Plain sandwiched between the Echigo Mountains and the Sea of Japan. Several Class A rivers such as the Shinano River, Agano River, and Seki River flow from the mountains to the plains, forming fertile alluvial soil. It belongs to the Sea of Japan climate and is known as an area with some of the heaviest snowfall in the country during winter. In particular, in the mountainous areas around the Uonuma Basin and Joetsu City, snow depth often exceeds 2 m, and this snowmelt water plays a role in stably supplying agricultural water from spring to summer. The annual average temperature is about 13 to 14°C, and the annual precipitation in Niigata City is about 1,800 mm, with summers becoming hot and humid. The agricultural zones can be broadly divided into four: the Echigo Plain (around Niigata City, Tsubame City, Sanjo City), the Chuetsu region of Nagaoka City and Kashiwazaki City, the Uonuma region centered on Minamiuonuma City and Uonuma City, and Sado City located on Sado Island in the Sea of Japan. In the Echigo Plain, field crops such as Watermelon, daikon (radish), and Edamame are grown in addition to paddy rice, and in the Uonuma region, the cool climate of the high-altitude mountainous areas contributes to the quality improvement of summer vegetables. Sado Island is influenced by the Tsushima Current and is also known as a production area for persimmons. According to crop statistics from the Ministry of Agriculture, Forestry and Fisheries (2023), Niigata's Watermelon production ranked 8th nationally (15,200 tons), and Edamame ranked 7th nationally (3,400 tons), showing its capability as a diverse fruit and vegetable production area behind its impression as a rice-producing region.

When discussing Niigata's agriculture, the presence of rice represented by Koshihikari (rice) cannot be avoided. However, while rice farming is the core of agriculture, there are notable production characteristics in the fields of vegetables, fruits, and fisheries. In the vast paddy fields of the Echigo Plain, daikon (radish) (ranked 8th nationally, 39,100 tons) and satoimo (taro) (ranked 7th nationally, 5,680 tons) are cultivated as rotational and catch crops, and the agricultural base of the rice-producing area supports the production of various vegetables. In fruits, the entire prefecture's persimmons (ranked 6th nationally, 8,920 tons), mainly produced in Sado City, and Le Lectier (Western Pear) (ranked 2nd nationally, 1,540 tons) around Niigata City serve as the faces of the prefecture, and both are traded at high unit prices due to limited distribution volumes. Along the coastline facing the Sea of Japan, Nanban ebi (sweet shrimp) and Nodoguro (Akamutsu) from the waters near Sado are caught, and agriculture and fisheries support the prefecture's food culture together. The climate conditions of the heavy snowfall area restrict agricultural work, but on the other hand, stable water resources from snowmelt and the temperature difference between day and night contribute to the production of vegetables and fruits. Behind the signboards of a rice-producing region, the reality of Niigata's agriculture is the presence of diverse fruits, vegetables, and marine products.
