Loved for 27 years, our signature “Amaka-Tare” sauce is now even more delicious with the savory depth of kombu dashi.





What Is “Kyushu Honjikomi”?
「九州本仕込み」とは?
For 27 years, Kyushu Honjikomi has been a household favorite.
Made with a base of Kyushu-style sweet soy sauce, our “Amaka” sauce has been refined again and again so that everyone—from children to adults—can enjoy it every day without ever getting tired of it.
Even after its launch, we’ve never stopped improving the recipe — all to keep earning that one word from our customers: “Delicious.”
With this latest update, we’ve deepened its umami and richness with kombu dashi, creating a flavor that makes you think from the very first bite: “This is exactly what I was looking for.”

I really love this natto. I’ve tried many different kinds, but the softness and flavor of this one are unlike any other—it’s truly delicious.
I eat it every morning and feel good. I live alone, so it's a little lonely to eat alone, but I'm eating the same natto as my family living far away, so I can do my best!
I’ve been eating Marukin natto since I was young. The texture of the soybeans is so soft, and it tastes absolutely delicious.
When my friend from Tokyo came to visit, I served them Marukin Natto, and they were so impressed, saying, “It’s delicious!”
Marukin Natto is truly “the pride of Kyushu.”
I absolutely love natto! Marukin Natto is the best. The softness of the soybeans and the white stringiness are unlike any other! I can't go a day without having at least one.
I’m writing this email because the Kyushu Honshigomi Natto was so incredibly delicious with an amazing texture.Please continue the great work! I truly appreciate it.
I absolutely love Kyushu Honjikomi Natto! The lid is made of plastic, which is eco-friendly and great!
About sauce
I’ve been eating natto every day without fail since I was young. Among all the options out there, Marukin Foods’ Amakatari is the most delicious.
After returning home from Aomori, where I got married, I was impressed by the taste, which was completely different from the natto with mustard that I had been eating there for 3 years!
When I eat Honjikomi Natto, my daughter is always nearby, tasting the sauce.
