Yuasa Soy Sauce Rosanjin is named after the famous Kitaoji Rosanjin and is released every year on March 23rd, Rosanjin's birthday, with a label bearing a serial number of the year that it was made for. It is a special soy sauce that is made using ingredients and production methods that are grown naturally without the use of any fertilizers or pesticides. When you pour the soy sauce onto a plate, the aroma is so fragrant that you'll think the soy sauce has been turned upside down, and it has a rich, umami flavor.
