Corporate Profile

In1900s, When Zenichiro Tomita planted tea trees in Nishio area, the largest Matcha production area, Nanzan-en’s history was started. Even after start of Matcha manufacturing operation, we still maintain our own private farms and have “integrated manufacturing system”, covering from tea farm to final product. Nowadays, we  are one of a few Matcha manufacturers having private farm in Japan.

Matcha is not only used for drinking, but also used for ingredients for any kind of foods. Use application of Matcha became widespread in these years. We try to step up efforts to food safety and quality of our products. We have installed  HACCP compliant Matcha factory in 2007 and have received certification of ISO 22000 (Food safety management systems) in 2009. On the other hand, Matcha is still being manufactured by traditional stone mills. It may look old-fashioned, however that is best way to create top quality Matcha. We are creating Matcha products under fusion of tradition and latest technology.

Nanzan-en realizes the potential of Matcha and contributes to assist in customer’s product development, human health, and maintaining traditional culture of Matcha.
