Family owned since 1888, Aiya is the world's leading Matcha green tea producer, headquartered deep within the Aichi Prefecture in Nishio city, Japan, where the finest Matcha green tea has been grown for over 800 years. The bulk of Aiya's Matcha is grown in Nishio in the heart of Aichi Prefecture, Japan. A historic tea cultivating region dating back to the 1200s, 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 the Nishio tea plantations.
