300 Years of History

Our founder, Kyujiro Koyama, began cultivating and processing tea in Ogura, Uji, Kyoto in approximately 1704. The Uji region is regarded as the premier producing area of the highest quality tea in Japan. Kyujiro Koyama’s work was the beginning of what was to become Marukyu Koyamaen. Successive generations made consistent improvements in all aspects of the cultivation and processing of tea, and hence Marukyu Koyamaen developed a reputation as a producer of superb quality matcha and other green teas. By the eighth generation, Motojiro Koyama, the company’s products were being marketed nationwide and in later years the company’s teas were being enjoyed worldwide.

Marukyu Koyamaen has refined its tea-producing capabilities over several generations by training employees to hone key skills and techniques, and effectively combining traditional know-how and modern technology. Our company maintains consistent high standards and superior quality from cultivation to the final product and has received awards in recognition of our efforts. The result is that Marukyu Koyamaen has gained a reputation for supplying superior quality tea that is highly esteemed, particularly in the traditional world of “Chanoyu”. We are proud that our company now ranks among the top producers of fine teas in Japan.
