We are a soy sauce manufacturer with a very long history of natural brewing in wooden vats, which has remained unchanged since our founding. Founded in Gunma in 1787, the company celebrated its 235th anniversary in 2022. We make our soy sauce using a process that has remained unchanged since the company was founded, fermenting it for approximately one to two years through natural brewing in cedar wood barrels. While most major soy sauce companies prepare soy sauce in stainless steel tanks in about six months, our soy sauce is naturally brewed and aged for a long time in wooden tubs that have been in use for over 100 years. This gives our soy sauce a very deep taste and aroma, and allows you to fully appreciate the quality of the ingredients. In addition, of the approximately 720,000㎘ of soy sauce produced in a year, only about 1% is made using wooden vats.
