Message from the President


When I heard "dashi",

What comes to your mind?

Dashi can be made not only from dried foods such as kelp and bonito flakes, but also from meat, vegetables, seafood, and any other ingredients.

In addition to the dashi that is prepared with great effort, there is also “natural dashi” that comes from the cooking process.

At the Dashi Sommelier Academy, from various angles about "Dashi"

We have prepared a comprehensive curriculum.

What       What kind of food do you like?

Where     Where can I get the material? Which country's cuisine is it used in?



How       How can materials be made?


Dashi expert = Dashi professional,

cherish the word


We will continue to walk.
