It is the origin of Japanese taste. It is a magical seasoning that turns various dishes into Japanese cuisine just by using a little bit.
Yuasa in Wakayama is called the birthplace of Japanese soy sauce. About 750 years ago around 1254 in the Kamakura period, Shinchi Kakushin (Hotto Enmyo Kokushi) zen priest studied the manufacturing method of “licked miso” at Kinzanji Temple in China and spread its manufacturing method as Kinzanji-miso in Kokokuji Temple in Yura, next town to Yuasa.
The liquid on the bottom of the Kinzanji-miso barrels was so delicious, it was the start to making soy sauce from that hint and spread around the surrounding area. Since Yuasa was flourished and the water of Yuasa was good to make that miso, Yuasa became famous.
In the Edo period, 92 soy sauce breweries were lined in Yuasa and receiving the protection of the Tokugawa Kishu clan. Soy sauce from Yuasa was shipped to Osaka and Edo and became known all over Japan and people come to Yuasa to learn how to make soy sauce. The population of Yuasa was the second largest next to Wakayama city in the end of Edo period.
Now it became a popular tourist spot in Wakayama. You can visit the old historical town of Yuasa and enjoy the nostalgic atmosphere.
In the year Meiji 14 (1881), Ms. Sumi Shinko began selling her handmade Kinzanji-miso in Yuasa. She was very good at making it so she was called “the master of making Kinzanji-miso”.
We carry on Sumi’s tradition and flavor and now Toshio Shinko is the fifth generation. We work hard to make a delicious product using only domestic ingredients even sourcing our sugar and salt, and we don’t use any chemical preservatives or additives.
Our carefully chosen ingredients are more expensive, but we take our role as Wakayama’s representative seriously and are dedicated to bringing you the best product.
We offer the most varieties of Kinzanji-miso in Japan, including low salt, Yuzu, and extra vegetables, and we are always creating new varieties for your enjoyment.
‘Tamari’, the liquid that comes out of Kinzanji-miso during fermentation, is said to have been the first soy sauce.
Yuasa Soy Sauce’s ‘Kuyo Murasaki’, actual tamari from Kinzanji-miso, takes us back to that time with a product that gets rave reviews. This tamari was the beginning of our soy sauce production business, and led to the founding of YUASA SOY SAUCE Limited.
