The people who make Chiba Soy Sauce

Chiba Soy Sauce has around 180 employees.

There are husband-and-wife couples who work at Chiba Soy Sauce, and parent-child pairs as well.

Among these, there are cases where there is a line of Chiba Soy Sauce workers extending over three generations.

In one case, the husband makes soy sauce, and the wife inspects the quality of the product.

Perhaps this husband is checked for quality by his wife even when he is at home.

Chiba Soy Sauce has large brewing barrels that have been continuously in use for over 160 years.

The mellow, high grade product that is Shimousa Soy Sauce is produced from nothing more than carefully selected whole soybeans, wheat, and salt, through the skills of our brewers and the subtle work of the yeasts that inhabit the barrels.
