Nagano

Nagano is an inland highland prefecture surrounded by mountains on all sides. The terrain with large elevation differences and the temperature differences characteristic of basins enable the formation of diverse agricultural production areas. The areas around the Matsumoto Basin, Suzaka, and Obuse are major production areas for Grape and Apple, where the temperature difference between day and night promotes fruit coloration and sugar accumulation. For Grape, various varieties such as Kyoho (grape) and Shine Muscat (grape) are cultivated, and the shipping volume is among the highest nationally. Nobeyama Highlands (Minamimaki Village and Kawakami Village) is a high-altitude cool-climate agricultural zone at an elevation of 1300 to 1400 m, with Lettuce production ranking 1st nationally (2023). The summer coolness supports a large-scale production structure that meets summer Lettuce demand, and during the peak shipping period from July to September, Kawakami Village alone accounts for a substantial portion of the national share. For mushrooms, the production volume of Enoki Mushroom and Buna-shimeji (Shimeji Mushroom) ranks highly nationally, with indoor cultivation concentrated near Nagano City. Nozawana (leafy vegetable) is a leafy vegetable said to have originated around Nozawa Onsen in northern Nagano, and its salt-pickled form (Nozawana-zuke) is distributed nationally as a representative pickle of Nagano. Shinshu Salmon (trout) is a freshwater-farmed trout variety developed by Nagano, served as sashimi and sushi toppings at restaurants in the prefecture.

The greatest characteristic of Nagano's agricultural structure is the use of topographical diversity with an elevation difference of nearly 4000 m by production area. From flatland rice paddies and orchard zones to high-altitude cool-climate vegetable production areas over 1000 m in elevation, different climate zones coexist within the prefecture, achieving production volumes and varietal diversity that cannot be reached with a single item. Lettuce from the Nobeyama Highlands is a typical example, having a clear role division functioning as an alternative supply area when the Kanto Plain faces difficulty shipping due to high summer temperatures. The mushroom industry is less affected by climate due to indoor cultivation, and production areas around Nagano City solidify their position in the national market using stable supply throughout the year as an advantage. For fruit trees, the topographical condition of temperature difference directly links to sugar content and color, naturally creating an advantage in quality. The culture of fermented foods such as Nozawana, miso, and sake is also rich, with a wide range of industries linking from primary agricultural production to processing and food culture. As a successful example of high-value-added agriculture that turns the constraint of being inland to its advantage, Nagano's agricultural model attracts high attention nationally.
