What is Gokuuma?
We’ve achieved a flavor that perfectly balances the umami of bonito flakes, kelp, and scallops with the sweetness of Kyushu soy sauce—combining classic ingredients for a taste that is both traditional and uniquely one-of-a-kind.

Driven by the desire to share Marukin Foods' proud natto with people across the country, we developed a unique sauce that reflects regional tastes. After many rounds of testing, we created a sauce with a perfectly balanced umami flavor using carefully selected ingredients.





*40 participants tasted the new product, Genki Natto – Supreme Kyushu Dashi Soy Sauce, and shared their feedback on how they felt about it.
Responses were gathered under the categories of "delicious," "not delicious," and "other," with the majority responding "delicious" (based on a Marukin Foods survey).
