In Koriyama, Horaiya Honten has been cultivating the art of koji, this essential fermented ingredient of Japanese cuisine. A legacy of Yutaro Yaginuma, the company makes its own koji thanks to traditional fermentation methods, refined generation after generation. Its ambition: to promote the culinary culture of koji throughout the world, through healthy and authentic products such as miso, sagohachi — pickles combining koji, salt and rice — or amazake, a sweet and naturally sweet drink.
