Vankoji Founder, Tonami, began selling Shiokoji in 2013 at the Nikeii Japanese culture center. She discovered Shiokoji while making her own koji (a powdery fungus grown on rice) for home made miso-paste. After reading about shiokoji’s popularity back in her homeland, Tonami decided to introduce it to local Japanese.
Since 2013, Vankoji has been producing and selling Shiokoji and other koji based seasonings at craft fairs and festivals.
Every year, sales has grown as more and more people from different nationalities enjoy this product in their every day cooking.
