Ryutsu Service Co., Ltd. was established in 1989 as the green tea processing division of Hattori Seicha, founded in 1905. After acquiring agricultural lands, we continued this far to a fully integrated production, including cultivation, tea processing, manufacturing, and sales.
Tea and coffee production, manufacture, and wholesale distribution. Bagging, bottling, canning, agriculture, and solar business. We are developing new Gyokuro, Matcha, and new tea varieties to change the declining tea industry. Following the motto “producing and selling our own,” we are not only answering the domestic demand but also enlarging our market abroad.
