Marukyu-Koyamaen started to cultivate and manufacture tea in the village of Uji and Ogura in Kyoto in late 1600 led by their founder, Kyujiro Koyama. Over the last 400 years, Koyamaen have devoted themselves to producing the highest quality tea generation after generation. Koyamaen are one of the oldest established tea manufacturers in Uji; they supply their high-quality tea to many prestigious temples, shrines, and tea ceremony houses. Koyamaen have acquired a number of notable awards at the annual National Tea Competition in Japan. Since 1962, Koyamaen have won the highly-coveted first place award 21 times. Whilst preserving tradition, Koyamaen promote technologically innovative production techniques. In recent years, Koyamaen have been focusing on developing new products such as their patented Mizutate Ousu in which Matcha tea can be made with cold water.
