Daitoku Shoyu was founded in 1899 in Tokushima Prefecture, Japan, with a single mission: to preserve the art of slow-brewed soy sauce in a world rushing toward shortcuts. The Tokiarubeshi Koikuchi was created for the home cook who feels modern, mass-produced sauces lack the soul and depth needed for authentic Japanese cooking. Every ingredient is sourced from certified organic Japanese farms to avoid the pesticide residues common in today's food supply. The formula is brewed in small batches for a full 18 months in 100-year-old cedar vats, a process certified by the Japan Organic & Natural Foods Association (JONA). This commitment has made it the top-ranked premium koikuchi soy sauce in Japan's natural food category for five consecutive years, chosen by chefs and families who refuse to compromise on flavor foundation.

Organic Daitoku Tokiarubeshi Dark Soy Sauce is crafted with a traditional Japanese recipe that includes organic soybeans, organic wheat, salt, and water. The organic soybeans serve as the primary protein source, undergoing fermentation to produce the sauce's rich umami flavor and deep color, while the organic wheat adds natural sweetness and aids in the fermentation process by providing carbohydrates for the koji mold. Salt acts as a natural preservative, controlling fermentation and enhancing the savory profile, and water is essential for dissolving ingredients and facilitating the brewing process. This combination results in a koikuchi-style soy sauce that offers a balanced, full-bodied taste with health benefits such as being free from artificial additives, gluten-free due to the fermentation breakdown of wheat proteins, and rich in amino acids and antioxidants from the organic ingredients, supporting overall wellness and culinary authenticity.
