Matcha Growing Region

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.

Orgnanic Matcha Growing Region

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.
