Family owned and operated since 1888, Aiya is the largest producer of premium Japanese Matcha green tea. Based in Nishio, Japan, Aiya oversees all phases of the Matcha production process, from seed to bowl, and is committed to providing high-quality organic and conventional Matcha to the world. Aiya America supports the North American market by supplying Matcha powder in bulk to manufacturers, wholesale quantities to small businesses and cafés, and Aiya Matcha branded products to retail customers.
The bulk of Aiya's Matcha is grown and produced in Nishio, the heart of Aichi Prefecture, Japan. A historic tea cultivating region dating back to the 1200's, Nishio’s stable climate, fresh pristine river waters, fertile soil, and remoteness from urban development foster tea leaves that are more resiliently green and full of nutrients. Currently, Aiya holds over 80% of the exclusive harvesting rights to Nishio’s tea plantations.
An important distinction between Aiya’s organic Matcha and conventional Matcha is the location of the organic tea fields. Our nutrient-rich organic Matcha is sourced from the island of Kyushu. Key farming location in this region is Kagoshima. Located on the southern edge of Japan, Kagoshima is an optimal location for growing organic teas because of its vast fields, mineral-rich volcanic soil, and remoteness from the city.
With a spotless product recall record of over 130 years, Aiya continually strives to improve product quality. Each step of the production process is thoroughly monitored and documented, and extensive internal and third-party laboratory inspections are conducted to ensure that the final product conforms to Aiya’s stringent standards prior to shipment. As part of its commitment to transparency, Aiya undergoes annual third-party audits and holds multiple international certifications for its pure Matcha green tea. These certifications include: GFSI (FSSC 22000 by Bureau Veritas), AIB (Superior), JAS Organic by OMIC, NOP Organic by QAI, Halal, Kosher, Gluten-Free, and Non-GMO Project Verified.
