Japanese tea producers have formally applied for Geographical Indication (GI) status for matcha, aiming to legally protect the powdered green tea as a product uniquely linked to Japan. The application, submitted to Japan’s Ministry of Agriculture, underscores efforts to preserve the authenticity of matcha amid rising global demand and the proliferation of imitations.

Geographical Indication status designates certain products as originating from a specific place, where their qualities or reputation are fundamentally tied to that location. This designation functions as a form of intellectual property, ensuring that names like Champagne or Roquefort can only be used for products made in their rightful regions. For matcha, GI recognition would mean that only matcha grown and harvested in Japan could be marketed as Japanese matcha, regardless of any blending or processing that might occur elsewhere.

The move reflects concerns among Japanese tea growers and merchants over the impact of the global matcha trend. In recent years, matcha has surged in popularity worldwide, not only as a traditional beverage but also as an ingredient in a wide range of drinks and food products. This widespread usage has prompted an increase in tea cultivation outside Japan to meet international demand, leading to questions about authenticity and quality.

The Japan Tea Central Public Interest Incorporated Association, representing the interests of domestic growers, stated that the GI mark would help consumers make informed choices by clearly identifying genuine Japanese matcha. The association emphasized the need to maintain the integrity of traditional Japanese tea, especially given the challenges posed by foreign-produced alternatives marketed under the same name.

If approved, the GI status will safeguard Japan’s matcha producers against overseas manufacturers who cultivate and sell matcha under the Japanese label, ensuring that the tea’s heritage and high standards remain closely tied to its country of origin. This step aligns with broader international efforts to protect regional products and prevent dilution of brand identity in global markets.
