Marukin Soy Sauce Museum
Since its establishment in 1907, Marukin Soy Sauce has been producing soy sauce with a flavor suited to the times while utilizing traditional methods in a natural brewery for more than 100 years. One of the buildings has opened to the public with a memorial commemorating the 80th anniversary of the company's founding in 1987. The gassho-zukuri building, the largest of its kind in Japan, is registered as a national tangible cultural property.
At the Marukin Soy Sauce Factory, you can get a glimpse into the traditional Japanese process of making soy sauce. Soybeans, wheat, and other ingredients are steamed, cooked, and made into koji, then mixed with salt water to ferment and mature. Only after pressing, blending, and other steps does the soy sauce develop its deep color and rich aroma. You can also appreciate the artisans’ many years of accumulated brewing expertise. Everything from the ratio of ingredients to the fermentation time affects the final flavor. After the tour, be sure to try the special soy sauce soft serve! It starts with a smooth, rich, milky flavor, followed by a subtle hint of soy sauce. The sweet and salty flavors are surprisingly harmonious, making this limited treat well worth trying while you’re here.
