Founded in 1902, in Saitama Prefecture, Japan, Yamaki Jozo is a family-run producer specializing in traditional, organic miso, soy sauce, and tofu. Known for using natural spring water and 100% Japanese-grown ingredients, the company emphasizes sustainable, chemical-free, and long-aged fermentation methods.
Around 40 years ago, current president Tomio Kitani transitioned the company to use 100% organic soybeans, inspired by natural farming methods and the organic direction has been at the forefront of its production philosophy at the company.
