The birthplace of soy sauce

The small coastal Japanese town of Yuasa is known as the birthplace of soy sauce. Fermented sauces made using soybeans had been around for centuries in China, but a Buddhist monk who settled in Japan in the 13th century started making soy sauce “as we know it”.

Using the abundance of clear, spring water from the town of Yuasa he began producing a type of miso that he had learned about on his travels that had been used to preserve vegetables. A byproduct from this process — a liquid that collected in the barrels of the miso paste — was soy sauce.

More than 750 years later, factories in Yuasa still produce soy sauce using traditional methods.
