Amanohashidate Winery is a chateau surrounded by the beautiful scenery of Amanohashidate, one of Japan's three most scenic views, and the Inland Sea, the Aso Sea. The winery's vineyard uses oyster shells collected from Amanohashidate and locally produced compost to grow grapes using methods similar to natural cultivation. Harvested grapes are produced by ripening them raw, without any heat sterilization, in order to preserve their flavor and fruitiness.
