Seasonings Soy Sauce Ambient Established export

Kamebishi, founded 1753, is the last brewery in Japan still using the labor-intensive 'mushiro koji' (straw-mat koji) cultivation method. Its flagship saishikomi (twice-brewed/re-fermented) shoyu is aged about three years in wooden vats for an intensely deep, sweet-umami profile prized for sashimi and finishing. The maker also produces a celebrated soy-sauce-infused Belgian chocolate. Distributed to Europe and the US through fine-food channels.
