Nishio | A Land of Tencha

Nishio, Aichi Prefecture, is one of Japan’s key tencha-growing regions, one of Japan’s few regions with an unbroken, eight-century tradition of shade-grown tea. Nishio is producing 20% of the country’s supply and more than 90% of its tea fields are dedicated to tencha, grown in volcanic soil and nourished by the Yahagigawa River. Generations of farmers have perfected shading, steaming, drying, and grinding, yielding tencha with richness, balance, and a smooth finish. Nishio remains central to matcha production in Japan and beyond.
