Prior to 1804

The Sato family was conducting a business as a kaisen-donya (wholesaler in port) shipping cargo on the nearby rivers.


The Sato family established San-Jirushi in Mie, Japan, as a Tamari soy sauce and miso company. The three river design of their logo came from the three rivers in the area that they used for their cargo-vessels when they were a wholesaler in port.

San-Jirushi established San-J to begin selling their Tamari soy sauce in the US as an importer and their products were very well accepted in the natural market.


The San-J plant was built in Henrico, Virginia. It was the first Tamari brewing facility built in the U.S.


The first stage of the plant expansion was completed to meet increasing demand of San-J products.


Takashi Sato, an eighth generation member of the founding family, is president of San-J, continuing the exacting standards for brewing the world’s finest Tamari soy sauce.
