Marukyu Koyamaen

Marukyu Koyamaen's history dates back to the Genroku era, when the first-generation Koyama Kujiro established a tea garden. Four generations later, the family began retailing their tea, and by the eighth generation, they expanded their distribution nationwide. With over 300 years of history, Marukyu Koyamaen remains committed to "tea-making with a focus on quality." They maintain strict standards for flavour and safety, overseeing the entire process from cultivation to production in-house. Consistently striving for excellence, they regularly participate in tea competitions and have been honoured numerous times with the prestigious Minister of Agriculture, Forestry and Fisheries Award.
