Yamaki Jozo

Established in 1902, Yamaki Jozo is a family run business that places importance on preserving nature. More than 80% of soy sauce produced in Japan is made with imported defatted soybean grits, and of the 20% that uses whole soybeans, less than 2% uses Japanese soy beans. Yamaki is one of the very few soy sauce breweries that uses whole Japanese soy beans.
They stick to natural and traditional methods for production, which means they brew their soy sauce according to the season instead of all year round.
