Aichi’s Matcha Heritage and Growing Landscape

Aichi Prefecture stands as Japan’s second-largest matcha producer, with Nishio city alone accounting for 20-30% of the country’s total matcha supply. While the prefecture ranks 11th in overall tea production with about 744 tons annually, it’s dedicated almost exclusively to matcha—roughly 90% of output goes toward powdered tea, much of it destined for food-grade applications. This specialization dates back to the 13th century when shade-growing techniques first took root in the region, establishing a foundation that continues to shape modern production.

The Nishio Advantage

Nishio city dominates Aichi’s tea landscape thanks to a combination of favorable conditions. The area sits at approximately 600 meters elevation, where volcanic terrain creates nutrient-rich, clay-heavy soils perfect for tea cultivation. Humid air from the Yahagi River maintains consistent moisture levels, while the mild climate supports year-round growth cycles. These geographic factors contribute to Nishio matcha’s signature profile: a smooth, mellow flavor with pronounced umami and minimal bitterness. The region’s producers cultivate proven varieties including Yabukita for balanced flavor, Okumidori for mellowness, and Samidori for unique taste characteristics.

Traditional Methods Meet Modern Challenges

Aichi’s tea farmers maintain cultivation practices refined over centuries. Shade-growing remains standard, with tea plants covered 20-30 days before harvest to boost chlorophyll and amino acid content. Many farms use natural fertilizers like wood chips and peanut bran to enrich soil without synthetic inputs. Ishikawa Seicha earned distinction as Japan’s first JAS-certified organic matcha farm, setting a standard others now follow. Hand-picking still occurs at quality-focused operations, though larger producers have mechanized to meet demand. The thing is, demand currently outpaces supply, creating shortages that strain the industry. An aging farmer population and declining numbers of new growers threaten future capacity.

Key Players and Production Focus

Several notable producers anchor Aichi’s matcha sector. Aiya Matcha operates as one of Nishio’s largest exporters, handling grinding and distribution on a commercial scale. Hekien Tea Junpei in Toyota City has won recognition for award-winning quality through traditional cultivation methods. The Nishio Matcha Museum promotes regional tea culture while educating visitors about production processes. Here’s what sets Aichi apart from other regions:

• Uji in Kyoto maintains an 800-year heritage and commands premium prices for ceremonial-grade matcha
• Nishio produces volume at competitive prices while maintaining smooth, sweet flavor profiles
• Shizuoka focuses primarily on sencha with smaller matcha operations

Most Aichi matcha enters food manufacturing channels rather than ceremonial markets, though high-quality ceremonial grades do exist. This positioning makes the region vital for matcha lattes, baked goods, and culinary applications. As organic production grows and international demand increases, Aichi’s role in supplying accessible, quality matcha continues to expand despite workforce challenges.
