Azumidaira spreads like a valley at the foot of the Northern Alps as shown in the attached photo. There is a mountainous area that looks like a small hill on the left bank of the Takase River that flows southward from Hakuba, and the tip of the mountain is Oshinoyama, and the Tennohara vineyard extends to the west-southwest facing the Alps at the bottom.
The right bank of the Takase River has a climate at the foot of the Alps, but there is clearly less rainfall on the Higashiyama side across the Takase River.
The amount of precipitation is about 1,000 mm per year, which is small in Japan and the sunshine hours are long. Since the Alps are towering like a folding screen, strong winds tend to be weaker than Matsumoto and Shiojiri.
The slope is around 10 to 15 degrees, so mountain winds and valley winds occur, so the wind is always moving.
Even in the summer, the fresh air blown from the Northern Alps passes through the valley and is well ventilated. With an altitude of 570 to 630 meters and an inland climate, the temperature range is large and even in the midsummer it becomes very cool in the morning. It seems to be the best environment for grapes to have a high sugar content.
