Kyuemon was founded in 1963 in Fukuoka, Kyushu, by a master chef who believed the stress of modern cooking was robbing families of authentic flavor. He created this concentrated tsuyu to deliver restaurant-grade dashi in seconds, using a proprietary extraction method that preserves delicate umami. Every batch is made in a Japanese GMP-certified facility, using only bonito flakes and kombu sourced from Kyushu's designated fisheries, which are tested for purity and heavy metals. This exact formula has been the top-selling concentrated tsuyu in its home region for over 15 years, trusted by Japanese households to elevate everyday meals without the traditional all-day simmering.

Kyuemon Kyushu-Style Concentrated Tsuyu Soup Base 300ml is a premium Japanese soup base that authentically captures the essence of Kyushu-style dashi. Its ingredients include soy sauce, mirin, sugar, bonito extract, kelp extract, and salt. Soy sauce provides the foundational umami flavor and rich color, while mirin adds a subtle sweetness and glossy finish that balances the savory notes. Sugar enhances the overall sweetness and helps mellow the saltiness, creating a harmonious flavor profile. The bonito extract, derived from dried skipjack tuna, delivers a deep, smoky umami characteristic of traditional dashi, and kelp extract contributes a mild, oceanic umami and minerals, enriching the broth's complexity. Salt is used to season and preserve the product. Together, these ingredients offer users a convenient, high-quality base for soups, noodle dishes, and sauces, delivering authentic Japanese flavors with ease, reducing preparation time, and ensuring consistency in homemade meals.
