Founded in 1872 by Maeno Yasukichi, Maruyasu Chagyō has been producing teas from around Shiga Prefecture, including their own tea from their hometown of Tsuchiyama, as well as from the famous growing region of Asamiya. While teas from these regions are often blended and sold as "Ujicha", Maruyasu celebrates the often overlooked teas of Shiga Prefecture.
