Marukin was founded in 1908. It still retains much of its original appearance since the opening and the soy sauce is made in the same traditional, old fashioned way.There is a long charred cedar fence that runs along the street about 150m, called "Shouyu Gura Douri" (Soy Sauce Brewery Street), and at the end of the fence just on the corner is Marukin Soy Sauce No.4 Brewery which is the called the Moromi warehouse. Inside the brewery, there are 4 moromi barrel sideways and a line of 153 barrels that is100m long. Preparation of moromi starts around the middle of January every year and collect the soy sauce by squeezing it in early December.
