FROM A SMALL TOWN
IN THE JAPANESE
MOUNTAINS

Dojo is brewed in a quiet mountain town in Japan, surrounded by forest, clean air, and natural spring water flowing down from the surrounding mountains.

THE PLACE + THE BREWER 土地と醸造家

120 YEARS.
FIVE GENERATIONS.
ONE MOUNTAIN TOWN.

At the foot of those mountains sits a fifth-generation family brewery founded in 1902. What began as a small koji-making operation has grown into more than a century of Japanese fermentation craft, with the same family still carrying the tradition forward today.

The brewery has spent generations refining one thing: how to turn a handful of simple ingredients into deeply flavorful soy sauce. They work slowly, use Japan-grown ingredients, and rely on the natural environment around them, including soft mountain spring water that flows directly to the brewery.

For Dojo, this is the point: great soy sauce starts long before it reaches the bottle. It starts with the place, the water, and the people who have spent generations learning the craft.

MEET MAMI + THE BREWERY 蔵の人々

THE PEOPLE
BEHIND THE
BARRELS.

Mami is the heart of our brewery, and you can taste her care in every bottle of DOJO.

She leads the craftspeople who work between the large wooden barrels, the way this family has for five generations. Nothing here is industrial: hands turn the koji, hands stir the moromi, and the people who make your soy sauce will happily feed you lunch afterwards.

THE FOUNDER 創業者

MEET CHAZ.

Chaz has always loved soy sauce. Maybe a little too much.

He put it on everything, but the bottles were messy, hard to control, and almost guaranteed to leave a stain. After spilling soy sauce on himself one too many times, he started wondering why such an essential ingredient had never been given a better bottle.

That question led to a much bigger discovery. Many of the soy sauces Chaz grew up with were produced in the United States for mass consumption, far removed from the patient brewing traditions that made Japanese soy sauce so special.

So he traveled across the world to Japan to experience the craft firsthand. There, he found a family-run, women-led brewery where soy sauce is slowly brewed with care, patience, and generations of knowledge.

Chaz created DOJO to bring that experience home: authentic Japanese soy sauce with deep, balanced flavor, packaged in a precision squeeze bottle that makes it easier and more fun to use.

What began with a spill became a mission to help America rediscover how soy sauce should taste.
