Past, present, and into the future – Yamaki katsuobushi bonito flakes and dashi broth.

Past, present, and into the future – Yamaki, the Katsuobushi & Dashi Company

 Yamaki was established as a kezuribushi (dried fish flakes and their mixture) manufacturer more than a century ago by Toyokichi Kido in Iyo city, Ehime, Japan. Since then, we have steadily grown while maintaining our devotion to provide the various values of Katsuobushi (boiled and dried-smoked skipjack tuna, also commonly known as Bonito) flakes and Dashi. We greatly appreciate that our journey would not have been possible without the warm support of all our customers and business partners.

 We have been continuously inspired and encouraged by our customers desire for “deliciousness” and have worked to enhance the spread of values of Katsuobushi and Dashi. We have developed a series of popular, long-loved products such as hana-katsuo (thinly shaved flakes of Katsuobushi), katsuo packs (Katsuobushi flakes in small packs), dashinomoto (flavor seasoning), "Men Tsuyu" (liquid concentrated Japanese noodle soup base), “Kappo Shirodashi” (Dashi based liquid seasoning), and nabetsuyu (liquid seasoning for Japanese hot-pot (nabe) cooking). Recently, along with retail market items, Yamaki has been proactively developing products for the food service and vendor industry and aggressively expanding overseas business opportunities. In addition to the taste and flavor values, Yamaki is seeking to spread and deliver the health values of Katsuobushi & Dashi to all people.

 As we head into the future, we will never lose sight of Yamaki’s key priorities. First, our social responsibilities as the Katsuobushi & Dashi Company. Secondly, our appreciation of nature and our commitment to promote and nourish a healthy environment for skipjack tuna. And lastly, but equally important, our credo of “Trust is the Foundation of Everything.” We, Yamaki members, will work together and provide the versatile values of Japanese originated Katsuobushi & Dashi to customers around the world. We will move forward to be the leading Katsuobushi & Dashi Company that contributes to the whole of society.
We look forward to your continuous and warmest support.
