Virginia's home for all things koji.
Break the mold and discover a new world of flavor!
Who we are
We're Koji House: a Virginia-based foodie collective putting modern spins on generationally proven Japanese traditions with seldom-seen ingredients like koji, sake kasu, and more!
We're on a mission to bring niche ingredients, ideas, and cultural staples to the mainstream through collaboration, innovation, and fermentation to honor Japanese tradition and enable the further exploration of this vast culinary world.
