A traditionally brewed Japanese soy sauce made in the spirit of Kanazawa’s long-established soy-making heritage, which dates back to the 15th century. 

Crafted from whole soybeans, it delivers greater depth and body, sitting somewhere between classic koikuchi and lighter usukuchi styles.

Often described as umakuchi, meaning “deliciously mellow”, this style is known for its natural sweetness and pronounced umami.

Naogen uses just four locally sourced ingredients: whole soybeans, wheat, sea salt and pure water drawn from Mount Haku. The sauce is slowly fermented for a full year in cedar barrels, allowing it to develop a rounded, full-bodied character with impressive length on the palate.

Rich, savoury and beautifully balanced, this is an authentic Japanese soy sauce with depth and structure rather than simple saltiness.

Available in 120ml.

Also available from this producer: Naogen Ginger Soy Sauce and Naogen Yuzu Soy Sauce.

Store at room temperature and away from sunlight.

Once opened, refrigerate and consume within 3 months.
