Marukyu Koyamaen is one of the most prestigious tea makers in Japan, having been producing matcha tea since 1704. Having developed the original production system, they now use a combination of modern and traditional processes to maintain as many historic elements as possible. They don’t grind matcha tea manually anymore, but they do use traditional stones. Supplying top tea ceremony schools, high ranking shrines and temples, and top hotels, they’ve won numerous tea competition awards.
