Teraoka Shoyu was founded in 1928 in the historic soy sauce region of Choshi, Japan, by master brewer Kichibei Teraoka. For nearly a century, the family has perfected a single mission: to create the purest, most versatile umami base for the modern kitchen. This Tsuyu formula was developed in response to home cooks seeking restaurant-quality depth without the time-consuming process of making dashi from scratch. We use only three core ingredients: first-press soy sauce aged in 100-year-old cedar barrels, bonito flakes from Kagoshima's single-day catch, and kombu kelp hand-harvested from the cold Hokkaido seas. Every batch is certified by the Japan Agricultural Standard (JAS) and brewed in a JFS-C (Japan Food Safety) certified facility. It has been the top-selling premium tsuyu in its category on Japanese e-commerce platforms for three consecutive years, chosen by over 500,000 households for its authentic, no-compromise flavor.

Teraoka Authentic Japanese Tsuyu Sauce is a premium umami base crafted from a traditional blend of ingredients that serve specific culinary purposes. The primary components include soy sauce, which provides a savory, salty foundation and acts as a flavor enhancer; mirin, a sweet rice wine that adds subtle sweetness and balances the saltiness while contributing to a glossy finish; and dashi, a broth typically made from kombu (kelp) and katsuobushi (dried bonito flakes), which delivers the essential umami depth characteristic of Japanese cuisine. Additionally, sugar is often included to round out the flavors and create a harmonious taste profile. These ingredients work synergistically to offer users a versatile sauce that simplifies the preparation of dishes like noodle soups, tempura dipping sauces, and marinades, ensuring an authentic Japanese flavor with minimal effort. The inclusion of natural umami sources like dashi not only enhances the overall taste but also provides a rich, satisfying mouthfeel, making it a convenient and high-quality option for both home cooks and culinary enthusiasts seeking to elevate their meals with traditional Japanese essence.
