Control by numbers and brew with 5 senses

In the stillness of the brewery, you can hear the sound of the growing moromi (mash of unmatured soy sauce).

The soy sauce brewing process is based on the importance of "brewing with all 5 senses": eyes (seeing), ears (hearing), nose (smelling), mouth (tasting), and hands (touching).

They keep a detailed record of numerical analysis and brew with all 5 senses.

 Moromi that is fermentation and maturation stages in soy sauce production is controlled using a stir stick, and any scattered moromi is wiped up each time.

It is easy to put into words that it is kept clean, but normally, splashes from the stirring of the various ingredients of soy sauce would adhere to the walls, but this is not the case at all.

Once a month, on a cleaning day, the ceiling, which must be at least 3 meters high, is also kept completely white all over.

The inside of the tubs are also wiped down every time.

The wiping process takes longer than the stirring.
They have been doing this for a long time and it has become a matter of course.

50 years of records are kept

They manage each process numerically, from the preparation stage as well as when shipping out products.

50 years of records are kept.
The staff members are so nervous without the numbers that numerical control has become a part of their DNA. 

Commitment to raw materials and attachment to Local

They put the value on the term "local production for local consumption" which means "to eat locally grown food locally.
Their commitment is to provide you with handmade soy sauce made from carefully selected local ingredients with the utmost care.
