The main ingredients in the sauce are soybeans, wheat, salt and water. We carefully select the best soybeans for making the soy sauce and continue to use traditional techniques to produce a superior product.
Dashi (Japanese Bonito broth)
The key factor in a dashi is good quality dried bonito flakes. We mainly use top-quality dried bonito flakes made from bonito caught in Makurazaki for our dashi extract.
We are always on the lookout for the best ingredients. We carefully select the natural flavors and pursue processing techniques that bring out the natural flavor of the ingredients.
Carefully selected bonito flakes from Makurazaki
The city of Makurazaki in Kagoshima Prefecture has a 300-year old history of producing bonito flakes and boasts the largest production of bonito flakes in Japan. Here, we use a traditional manufacturing method called "Satsuma-style" and use dried bonito flakes that have been smoked for a long time.
Bonito flakes are shaved before being used in-house
At Nibishi, we always buy our bonito unshaved and store them in a temperature-controlled refrigerator. This is because bonito’s aroma is lost over time when it is shaved. When we make our own dashi, we use flakes that are shaved at our own factory.
Importance placed on using thick shaving
By shaving the dried bonito thicker than the dried bonito flakes available in the market, we are able to produce a stronger dashi that is free from any unpleasant tastes and suits the taste of locals in Kyushu.
The "first" dashi extracted in-house
At Nibishi, every time we make soup, we actually extract the dashi in the same way that we used to use at home. Moreover, we place great importance on using only the refined and transparent "first dashi."
Blessed by the purity of the Kiyotaki Valley.
Water is also an important part of the soy sauce making process.
Water accounts for less than 70% of the ingredients of soy sauce. It cannot be ignored.
At Nibishi, we source groundwater from the Daikon river which originates in the Kiyotaki valley, at the foot of the Inunaki mountain range. After aeration, the water is passed through a filtration and adsorption system and an ion-exchange resin system where it is converted into soft water suitable for food production and then used in our products.
A world of flavors created by live koji.
Making koji is the most important process when making miso and soy sauce.
Good raw materials, right amount of time, and expert craftsmanship are all needed to produce good koji and delicious brewed products.
Rice, barley and other raw materials are suitably processed and placed in the koji making room. The koji is then incubated for three days, taking great care to create the optimum environment in terms of humidity and temperature to produce high quality koji and delicious miso.
Our flagship product "Satogokoro Awasekoji" is made by mixing rice and barley evenly at the koji making stage, leaving the koji grains to improve the appearance and flavor of the finished product.
