Tochigi Prefecture is landlocked, with hot summers and cold winters, resulting in significant temperature differences both diurnally and annually. 

These variations are beneficial in balancing the sugar and acid levels in grapes. Additionally, the soil in Tochigi is predominantly volcanic, which provides good drainage.

There are also regions rich in minerals, making these soil conditions well-suited for grape cultivation.

Grape varieties originating from America such as 'Niagara' for white wine and 'Concord' for red wine are commonly grown, but in recent years, international and unique Japanese grape varieties have also begun to be cultivated.
