When the Sato family began making soy sauce and miso as the San-Jirushi company in 1804, they started a legacy that still boldly endures. Eight generations have passed along the method of brewing high-quality Tamari from 100% of the finest soybeans resulting in more soy protein contained in the finished product, resulting in a milder taste and higher complexity of flavors in the sauce. It is said that Tamari is the origin of Japanese soy sauce.
