Highlights

• Exceptional 15-koji ratio — more rice koji than most Shinshu miso, creating natural sweetness that rounds and balances the salt

Producer's Story

Sukyu Shoten has been fermenting miso in the mountain city of Komoro, Nagano, for approximately 350 years — making it one of the oldest continuously operating miso houses in Japan. Their flagship brand, Yamabuki, draws its name from the golden mountain rose that blooms each spring along Nagano's rivers. In 2026, their miso tasting set earned a Gold Award at the Japan Food Selection, affirming what generations of Japanese families have long known.

Flavor Profile

Yamabuki Koji Miso opens with a gentle, rice-forward sweetness — the unmistakable character of a high-koji Shinshu miso. The salt is present but soft, drawn back by the natural sugars of the rice fermentation. Underneath, a clean soybean umami lingers, making each spoonful feel satisfying without being heavy. It is the kind of miso you reach for every day.

Cooking Ideas

Classic miso soup with silken tofu and wakame; a miso-butter sauce stirred into pasta or spread over grilled corn; a quick miso glaze brushed onto salmon before broiling; whisked with rice vinegar and sesame oil into a dressing for grain bowls or roasted vegetables.
