Marukyu Koyamaen is one of Japan’s most respected producers of green tea and matcha, headquartered in Uji, Kyoto Prefecture, a region internationally renowned for its premium tea heritage. The company’s origins trace back to around 1704, when Kyujiro Koyama began cultivating and processing tea in the Ogura area, laying the foundation for what would become a centuries-old tea-making tradition.

Over more than 300 years, the Koyama family has refined its expertise in tea cultivation, leaf selection, and processing, establishing Marukyu Koyamaen as a benchmark name in high-quality Uji tea. The company is particularly celebrated for its matcha, produced from shade-grown tencha leaves that are carefully steamed, dried, and traditionally stone-milled into an exceptionally fine powder.

Its portfolio includes ceremonial-grade matcha, everyday drinking matcha, and specialized varieties intended for culinary applications and confectionery use. Beyond matcha, Marukyu Koyamaen also produces other classic Japanese green teas, including gyokuro, sencha, hojicha, and genmaicha.

The company combines deeply rooted traditional craftsmanship with modern quality control standards, maintaining consistency across its premium tea offerings. Thanks to its longstanding heritage and uncompromising focus on quality, Marukyu Koyamaen remains one of the most recognized and respected names in Japanese tea production.
