Rice vinegars brewed using traditional methods for legendary taste and mildness. History In the Tokugawa Era there was a saying that ”Masamune means Sake and Marukan means vinegar,”and as a guarantee of the unfailing quality of Marukan vinegar, the name of the company’s founder, Suya Kanzaburo (Yasuhisa) was written on every barrel of vinegar produced. Later the first character of that name, written like this was designed to the present trademark , and right up to the present day this trademark has continued to stand as a guarantee of our traditional skill and constant high qualityProducing rice vinegar with legedary taste and mildness takes time.
