Founder, Kyujiro Koyama began cultivating and processing tea in Ogura, Uji 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 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 world-wide.
